The first step in collecting training data for machine vision is to design your image acquisition system. The images you acquire for training and inference may be negatively impacted by a poorly designed imaging solution. On the other hand, a well-designed image acquisition system will boost your model’s accuracy and sensitivity. In this article, we explain how to design an image acquisition system solution with machine vision examples.
We will cover the following key factors for creating quality images needed for training your model.
- Field of View
- Depth of Field
- Color vs black and white
After collecting a set of images you may find that some are not optimal. Instead of discarding them and starting over you may be able to reuse them with some post-processing to alter the image. Then use the edited image for training. The result of completing this step is a set of quality images used for training your system.
Collecting Sample Data
As a first step we want to capture many samples showing the target object clearly in the image. Then we evaluate the images for how clearly they show the target object. This shortens the processing time for iterating through the data set, We want to build a lab environment to quickly test different factors that will affect the quality of photographic images.
One of the image solutions we designed was for detecting leaks in air compressors. They were pressurized and submerged into a tank of water. This created bubbles coming from any leaks. In this article we’ll use this example to discuss various aspects that affect the imaging solution.
Let’s start by discussing the factors that affect the quality of your images.
Environmental Factors Affecting Image Quality
The previous section discussed camera settings controlling the exposure. In the next section we’ll discuss factors that are outside of the camera. These are the environmental factors.
Lighting is critical for successful imaging. If after adjusting the three exposure settings you do not have enough available light, then you have to look to the lighting equipment. Proper lighting is specific to the nature of the image analysis and depends on the specific environment and object(s) being captured. Lighting can highlight desired aspects or diminish unwanted ones. You will need to experiment to find the optimal lighting for your needs.
There’s a number of different lighting options such as direct, backlight, or diffused light.
- Direct light would be used to reveal the surface and create sharp shadows. Depending on the angle of the light to the angle of the camera, known as the angle of incidence, direct light can be used to enhance edges and texture.
- Backlight can highlight edges and separate an object from the background. Taken to the extreme, backlight can create a silhouette to reveal the object’s outline with no detail of its surface.
- Diffused light, or scattered light, reduces shadows. This would be effective for removing unwanted shadow textures that can interfere with capturing details on the object’s surface.
A dedicated article of lighting is needed to cover this topic adequately. Here we’ll cover just one example of how lighting affects image quality. In our leak detection, proper lighting would highlight the bubbles and help separate them from the background. Below is a comparison of images under different lighting conditions.
Inside a photography studio, you typically see subjects in front of a pure white or black background. This hides distractions and separates the subject. This sample principle applies to machine-based visual inspection. We want a distraction-free background. Then human workers, as well as the AI models, can give their attention to the important areas and therefore more likely to catch defects.
In our air compressor example the back of the inspection tank was a glass wall. That allowed inspectors to see the back of the compressor, but this also created a problem.
The glass wall reflected anything in front of the tank, such as lights, people, and other bright objects in the room. These unwanted objects in the image distracted the model. In the image below you can see the reflection of two tubes.
A simple fix was to add a black background. This prevented the reflections. Additionally this increased contrast and that helped to highlight the bubbles.
Look at the image below. You can easily find the small bubbles when using a black background. Now look back at the image above and notice how much harder it is to spot the bubbles.
Field of View
The lens focal length and image sensor size determine the physical area of the subject that can be captured. In other words, how wide of a shot can be obtained. Wider lenses and large sensors can capture a larger field of view. Increasing the distance from the subject to the camera can increase your field of view.
The image’s resolution will be determined by the size of the camera sensor and the field of view. Higher resolution can increase the accuracy of the subject.
In our example we need to capture an image of sufficient resolution that includes the entire air compressor and some distance above it for the rising bubbles.
Control Exposure With Camera Settings
The amount of light captured by a camera’s sensor is referred to as the exposure. There are just three factors that determine the exposure. If one factor is too low, we can increase it by trading that for another. The three main camera settings controlling exposure are:
- Shutter speed – adjusts the amount of time the sensor gathers light
- Aperture – adjusts the amount of light that passes through the lens
- Sensor sensitivity – adjusts the sensor’s sensitivity to light, measured as ISO
Each factor also affects different qualities of image capture. This is another dimension of the art of photography. Unlike art, machine vision isn’t about creativity. The goal is to obtain the best quality image. Here’s the trade off to consider when adjusting the exposure.
- Shutter speed – faster speeds are needed to freeze motion but reduces the amount of light reaching the sensor
- Aperture – wider settings will increase the amount of light on the sensor but reduces the depth of field
- Sensor sensitivity – higher levels of sensitivity will increase noise
If you need to increase the shutter speed, or exposure time, then to compensate for the lost amount of light you need to increase one or both of the other factors. You have to find the right balance of all three for the best image.
With low levels of light, we can extend the exposure time, or shutter speed. This comes with a tradeoff.. You may have seen photos of fast moving objects such as a race car using a long exposure time, or slow shutter speed. The object looks smeared in the image. This effect is called motion blur. While this might look exciting for photos of cars during a race, it’s bad for machine vision.
In the following examples of a spinning pinwheel, each of which are spinning at the same speed. The exposure time ranges from slow to fast. The amount of the light coming into the camera is kept the same by adjusting the aperture and camera’s sensitivity. As you can see the faster exposure time appears to freeze the motion, producing a sharp image.
Different exposure times of object in motion
The lens’s aperture controls the depth of field, or DOF. This is the distance from the nearest to the furthest object that is sharp in the photo. Objects outside of the DOF will be less sharp. Increasing the DOF reduces the amount of available light reaching the sensor.
The ideal setting is one that has all the target objects within the DOF, but no more. This way we can optimize the amount of light in the exposure. We increase the DOF by reducing the aperture size. This lowers the amount of light in the exposure. To compensate for this we can increase the sensitivity at the sensor, the ISO setting.
In our example of detecting rising air bubbles, increasing the DOF makes our model more accurate at detecting any bubbles rising from the front or back of the compressor.
The sensitivity to light in a camera can be adjusted. This is the ISO value. Higher values mean higher sensitivity. But higher sensitivity comes at a cost. It introduces digital noise. These are unwanted artifacts in the image. You adjust the ISO in relation to shutter speed and aperture settings. Just be cautious you are not allowing noise in the images to affect your model.
Color or Monochrome
There is one more camera setting that might be a consideration. Monochrome, or black and white, images have the advantage of being more efficient at capturing lower levels of light. If color is part of your image analysis, such as spotting a red object, then obviously you have no choice but to capture in color.
Low levels of light can introduce color artifacts of digital noise and chromatic aberration. Using monochrome images we get increased brightness with less noise.
Reusing Images for Training
If we’ve changed camera settings or the environment, after training our models we need to retrain. However, don’t throw away the old data! You may be able to reuse those images. For example, if the originals were in color and you’re switching to monochrome, convert the originals to grayscale. There are many software applications for photographers that will make this conversion easy and perform it on a folder of images in one batch.
Once the old images are converted they can be reused in model training, probably with lower weights during backpropagation. This old data, as generated in various production settings, is very good for data augmentation and makes the output model more robust.
Build a Test Environment
In addition to the background and lighting, there are other factors that could affect visual inspection tasks. In our example this would include water condition and air quality. Experimenting with those factors in a real production environment may be time-consuming and may not be feasible.
We recommend that you set up a lab that mimics the production environment and run controlled experiments. Test both qualitative or quantitative evaluations. Then, once you find a better environment setting, generalize and apply it to the production environment. This method will help you quickly iterate without disturbing the production environment.
In this article, we discussed the key factors that will affect machine vision. We explained the basic controls that determine exposure and how to improve the physical environment.
You may wonder why so much effort should be spent setting up an imaging solution. Through our experience, we have found that an optimal camera configuration has a critical impact on the project’s overall success.
We’ve encountered scenarios when in the middle of our model iteration, we would find our model’s performance negatively impacted by the input imaging quality. This meant going back and readjusting cameras and/or the environment. Every time we make such a change, the data distribution changes. This in turn forces us to collect new data and retrain the model. This process is costly.
Therefore, we strongly recommend that you spend more effort in the beginning of the AI project. Tune the camera and environment through multiple experiments. Better images means there’s less chance of having to start over.
- Quality of images needed in model training is controlled with lighting, background, and camera settings.
- Experiment to determine the best image acquisition solution.
- You may be able to reuse existing images with post-processing.

What is UV radiation?
UV rays are high energetic, electromagnetic rays, occurring in the natural spectrum of the sun.
For UV disinfection the bactericidal UVC range (200 - 280 nm) is used and here the specific wavelength of 254 nm. The absorption maximum of microorganisms lies at this wave length, from which results the germicidal effect.
In addition, the UV radiation can also be used to reduce TOC (total organic carbon). The energy-rich UVC radiation is made use of in the wave length range of between 200 – 280 nm and, contrary to disinfection, also of the VUV (vacuum UV) in the interval of 100 – 200 nm.
In several fields of industry, ozone is increasingly being used for disinfection and cold sanitisation purposes of ultrapure water storage and distribution systems. Before using the water in processes, the ozone has to be destroyed. In this case the destruction of residual ozone by UV is the ideal process. However, only lamps with a wavelength of 254 nm were used.


A review of Fiber optical parametric amplifiers is presented. Theoretical framework necessary to understand fiber nonlinearities are provided with emphasis on Four – wave mixing, a nonlinear phenomena that transfers energy from a strong pump wave to two waves, a signal wave and a generated idler wave. Fiber optical parametric amplifiers (FOPA) are based on Four–wave-mixing (FWM). FOPA have the prospects of use in several applications of optical communication systems. They can be used for linear signal amplification, wavelength conversion, all – optical signal sampling etc. Such amplifiers exhibits lower noise figures with feasibility to achieve 0 – dB noise figure and they have the ability to operate over arbitrarily centered and wide wavelength ranges. FOPA are certainly enablers to increase overall capabilities of wavelength – division – multiplexed (WDM) optical communication systems.

It is a well known fact that light can have an impact on the conduction of some types of diodes. LEDs have been used as photodiodes in certain circuits.
I theorized that light could be used possibly control the clipping point and/or the knee of the diode conduction curve. A quick search through my parts bin yielded some glass 1N4148 silicon diodes and a few clear 1N34a germanium diodes, which were perfect for the experiment.
I arranged a selected diode on a breadboard with a red LED positioned to illuminate the glass body of the diode. A small black opaque 35mm film can was used as a cover to shield the setup from ambient light. The LED could be activated from outside the film can shield by applying power to the breadboard.
With the LED off, I measured the forward voltage (Vf) of the silicon diode at 550mv. Then I powered up the LED and measured the Vf… still 550mv.
Next I put the germanium 1N34a into place in front of the LED. It measured 265mv with the LED off and 265mv with the LED on. So far, it’s a bust.
I tried both diodes with a bright yellow LED, then a green one and finally a really bright blue LED. In no case did the Vf change from the 550mv and 265mv values! I switched meters and measured the Vf with a different meter and then with a diode tester. No change.
Bottom line is that light does not seem to have any influence on the conduction of the diode.
Not all good ideas work out

Apple has filed a patent (number 20130039508) with the U.S. Patent & Trademark Office for an image capturing device having continuous image capture. It involves cameras, handheld electronic devices and, well, other electronic devices.
Here’s Apple’s background and summary of the invention: “These image capturing devices typically use a preview resolution for capturing a preview image of a scene. Subsequently, a user provides an input to take a photograph. The device switches from preview resolution to full resolution prior to capturing an image. Switching from preview to full resolution causes a time lag, which may lead to user frustration. Also, camera shake during the time when a user presses a button or touches a touchscreen can degrade image quality.
“Methods, devices, and systems for continuous image capturing are described herein. In one embodiment, a method can include continuously capturing images with an image capturing device. The method can include storing a predetermined number of the sequence of images in a buffer. The device can receive a user request to capture an image. The method can automatically select one of the buffered images based on one or more parameters.
“For example, the selection may be based on an exposure time of one of the buffered images and optionally an image quality parameter (e.g., image contrast). Alternatively, the selection may be based only on the image quality parameter. The sequence of images can be captured just prior to or concurrently with receiving the user request. The method can include automatically displaying the selected image on the display of the image capturing device. These operations can be initiated after the device enters an image capturing mode or other mode.
“For example, the device may have many functions and capabilities (e.g., the device may be a smart phone or personal digital assistant (PDA) which can send and receive emails, allow surfing of the internet, create documents, and also act as a camera), and a user can place the device into camera mode in order to cause it to begin these continuous operations. In an embodiment, the device is not continuously performing these operations when it is not in camera mode.
“In an embodiment, the continuously captured images can be captured in full resolution. The sequence of images can be advantageously captured just prior to the device receiving the user request for the photograph to avoid camera shake associated with the user request (e.g., pressing a shutter button, touching a touchscreen). One of the sequence of images can be automatically selected and displayed in full resolution in response to receiving the user request.

Sky-Watcher was launched in 1999 featuring a modest line of Newtonian and refractor style of optical tubes with limited distribution in Europe and Asia. Founder David Shen got his start in the telescope industry as a polishing technician and observed that the industry had a demand for more intuitive, user-friendly products. In 2000, Sky-Watcher released their first series of Dobsonian telescopes, and two years later answered the rising popularity of digital SLRs with their first version of the famed German Equatorial Mount, the EQ6. Today, with a full product line that includes Dobsonians, APO refractors, EQ mounts, and photography products, Sky-Watcher has grown into the most popular telescope brand worldwide.
Although small, the Sky-Watcher USA team of Jeff, Kevin and Alex form a motley crew dedicated to providing you with the best quality astronomical & photography gear at the best possible price.

Project Title: SocialFilm
Sponsor: Austrian Research Promotion Agency (FFG),
Industrial Partner: emotion3D
Duration: 5 months (July 2017 – November 2017)
AbstractCurrent smart phones and digital cameras allow users to create high-quality images easily without the need for professional expertise, e.g., in the field of photography. Based on fully automatic image analysis (for example, detection of closed eyes, automatic white balance, etc.), the device supports the user in taking pictues. In contrast, the creation of good short videos with the smart phone is still not easy to accomplish for the amateur users, since good camera movement puts significantly higher demands on them. To overcome this issue, emotion3D is working on a fully automated software tool to support users in the video production process on smart phones. This tool analyzes the quality of the video during recording, using intelligent image analysis (such as Optical Flow or Visual Odometry) and IMU sensors. It can identify and alert the user about aesthetic mistakes, e.g., poor camera direction or scene composition.


There are three main uses of outdoor lighting:
- Increase safety and security
- Extend the use of outdoor areas
- Enhance the appearance of the home
As will all lighting, outdoor lighting has benefited from the application of light emitting diode (LED) alternatives to incandescent, compact fluorescent (CFL), and various high intensity discharge (HID) forms like mercury vapor, halogen, and sodium.
LEDs are an ideal outdoor light source because they have significantly longer lifespans (up to 10 years), use substantially less energy, can have their light pattern carefully controlled to prevent light pollution on neighboring areas, have excellent color rendition, and perform well in colder temperatures.


Researchers from the Nanyang Technological University in Singapore and the University of Leeds in the UK have developed a new type of laser technology that will revolutionize the manufacturing of lasers.
The research in electrically driven topological lasers lasted two years and conducted by a team of physicists and engineers from NTU Singapore and material scientists from the University of Leeds.
Which included Professor Qi Jie Wang, Associate Professor Baile Zhang, Associate Professor Yi Dong Chong, DrYongquan Zeng, Professor Giles Davies, Professor Edmund Linfield, and Dr Lianhe Li.
The goals of this research were to combat current laser manufacturing flaws by exploring the topological states of matterâleading to the creation of the first electrically-driven topological laser.
Basis of the Research
The concept for a topological laser comes from the theoretical discoveries of topological phases of matter done by scientists D. J. Thouless, F. D. M. Haldane and J. M. Kosterlitz in the 1980s, for which they were awarded a Nobel Prize in Physics in 2016.
Even though topological phases are a recent concept in the physics of condensed matter, as theyâre emerging as the potential basis of future technologies in the fields of optics, photonics, and quantum computing.
Topological phases of matter imply that materials called topological insulators (which are materials that have insulating properties in their interior but have a highly conductive surface), exhibit topological features allowing particular particles (such as photons and electrons) flowing within the material to round corners and circumvent manufacturing flaws without scattering.

Manufacturing Defects in Semiconductor Lasers
Today, much of our technology depends on electrically-driven semiconductor lasers. Devices based on these lasers utilize light to read, write, transmit and receive data to perform a specific function.
Everyday devices that use semiconductor lasers include barcode scanners, laser printers and laser disk readers. Lasers are also commonly used in research, manufacturing and in medical fields.
Nevertheless, these types of lasers exhibit manufacturing flaws that leave many produced batches with unusable laser modules due to the imperfections that arise in manufacturing and packaging. This happens because laser light scatters when it encounters defects in the material itâs traveling through.
Such a problem is unavoidable when it comes to conventional semiconductor lasers due to their design and manufacturing processes.
The First Electrically-Driven Topological Laser
To combat the problems that arise in laser manufacturing, the team from NTU and Leeds applied the scientific phenomenon of topological phases of matter to a practical electronic device.
The team developed a new laser design that incorporated a valley photonic crystal which is a photonic analogue to the topological material known as a two-dimensional valleytronic insulator.
Like regular semiconductor lasers, this laser is fabricated out of a semiconductor wafer, with the key difference being the design of its structure. The topological laserâs microstructure is comprised of quasi-hexagonal holes, drilled into the semiconductor wafer and arranged in a triangular lattice, making it highly compact.
Light passing through the microstructure of the topological laser is capable of propagating within the lattice in a unidirectional matter. Rounding the sharp edges of the triangles without reflection accumulating light energy and forming a laser beam.
This occurs thanks to the photonic topological material used to manufacture the laser module.
A notable characteristic of this laser is that it emits light at terahertz frequencies, which on the electromagnetic spectrum; found between microwaves and infrared radiation.

Not the First Topological Laser
This laser is not the first topological laser, but the first electrically driven topological laser. Researchers from the Technion - Israel Institute of Technology and the University of Central Florida in the USA developed an optically driven topological laser in 2018 by using multiple optical resonators achieving the effect of laser light rounding corners without scattering.
The problem with conventional implementation of the laser was its size, due to the multiple modules it was comprised of, as well as its reliance on another laser (a semiconductor one), to power it.
Emerging Technologies Based on the Research Findings
Even though this type of technology is in its very early stages it shows a lot of promise. The field of optics and photonics is essential in current and future technology and can potentially benefit a lot from topological lasers.
To begin with, this technology can potentially eliminate a lot of wasteful manufacturing practices and reduce the amount of defected laser modules.
Moreover, due to the terahertz frequencies of the light outputted by the laser, it might find new uses in sensor technology, computing and high-speed optical and wireless data transfer. Which includes areas such as quantum computing, Li-Fi communications, LIDAR and similar technologies.
All in all, as new research is conducted and this technology gets funding, we might see topological lasers become the basis of our future communication and computing devices.


Our long-pulse NdYAG laser produces a wavelength of 1064nm, ideal for several applications, including vascular treatments, hair removal, and skin rejuvenation.
This Coolglide laser was developed in the U.S. by world leading laser company Cutera.
Coolglide can treat small and larger, reticular, vessels in the legs, without the need for compression afterwards. Our 1064nm NdYAG laser also targets deeply enough to bypass the epidermis (top layer) and destroy hair follicles.
Unlike many other lasers and IPL, the 1064nm laser is one of the only lasers that is safe for treating black skin for hair removal. The short pulse width setting with this laser allows us to deliver laser energy to heat the skin to tighten pores, reduce redness, and smooth skin.
Laser Genesis, a relaxing laser facial, treats the skin in this way by firing thousands of laser pulses into the skin with no pain or discomfort.


In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually collect radiation only within a specific bandwidth.
Thermal infrared radiation also has a maximum emission wavelength, which is inversely proportional to the absolute temperature of object, in accordance with Wien's displacement law.
These letters are commonly understood in reference to atmospheric windows and appear, for instance, in the titles of many papers.
Near-infrared is the region closest in wavelength to the radiation detectable by the human eye.
Infrared spectroscopy examines absorption and transmission of photons in the infrared range.
Infrared radiation is used in industrial, scientific, and medical applications.
Sunlight, at an effective temperature of 5,780 kelvins, is composed of near thermal-spectrum radiation that is slightly more than half infrared.
At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level.
Of these natural thermal radiation processes only lightning and natural fires are hot enough to produce much visible energy, and fires produce far more infrared than visible-light energy.
Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.
Thermal-infrared imaging is used extensively for military and civilian purposes.
Slightly more than half of the total energy from the Sun was eventually found to arrive on Earth in the form of infrared.
The balance between absorbed and emitted infrared radiation has a critical effect on Earth's climate.
The three regions are used for observation of different temperature ranges, and hence different environments in space.

Sunglasses That Help Your Eyes as Well as Your Look
Children are particularly weak to eye harm from UV rays. The lens inside their eyes remains to be clear and their pupils are wider than in adults, which permits extra damaging rays to achieve the retina the place visible photos must focus if we’re to see them. Once the retina is broken, visible impairment is more likely to be everlasting.
Here’s what to contemplate when selecting lenses that may shield your eyes from the hazards of UV overexposure.
All sun shades, even these bought at greenback shops, ought to now include full (400 mm) UV safety, though costlier lenses present higher visible readability. The shade of the lens doesn’t matter, although gentle tints are usually not as efficient for folks whose eyes are very delicate to vivid gentle. If the label says UV 400, chances are high it’s true or very near it.
[Wirecutter’s suggestions for affordable sun shades.]
Michael Stoff, the optician-proprietor at Eye Shoppe on 7 in Brooklyn, the place I’ve purchased all my new glasses, advised me that the polycarbonate materials of most sunglass lenses and lenses made from glass naturally blocks UV rays, however UV safety needs to be added to plastic lenses. If unsure concerning the UV safety afforded by your present glasses, ask an optician who has a spectrometer to examine them.
Ideally, each common eyeglasses and sun shades ought to have anti-reflective coatings on either side of the lens, which is why I spent a bit of additional to get Crizal lenses that shield my eyes from UV gentle coming from behind me in addition to from the entrance.
I additionally bought photochromic lenses — greatest identified on this nation because the model Transitions — in all glasses I’d put on outdoor. They have wonderful UV safety, Mr. Stoff mentioned. When uncovered to UV, even on hazy days, the lenses darken, then clear in a minute or so once you go indoors. The newest model of Transitions lenses, referred to as Gen eight, launched July 10, supply the perfect safety, he mentioned.
However, photochromic lenses don’t darken in a automobile as a result of windshield glass blocks UV gentle. And they don’t get as darkish as dark-tinted sun shades so might not work nicely sufficient for eyes very delicate to daylight. But should you put on contact lenses, now you can get photochromic contacts, marketed by Acuvue since March.

What Is A Laser?
A laser is a device that produces a very strong and focused beam of light. One little known fact is that our surgical laser produces a beam that is even more powerful than a similar-sized beam leaving the surface of the sun!
Years of experience in human and veterinary medicine went into the design of the Aesculight lasers, which were made specifically to provide superior care for pets. Ask your veterinarian about CO2 laser surgery.
Why Pet Laser Surgery?
Traditional surgery with a scalpel or scissors can bruise or crush soft tissue, while a powerful, concentrated laser beam has the unique ability to instantly vaporize or “erase” unhealthy tissue, as well as make incisions. The laser minimizes pain, swelling, and bleeding often associated with surgery. The beam simultaneously kills any bacteria in its path (i.e. bactericidal effect). In addition, during CO2 laser surgery, only an intense beam of laser light touches the tissue, which reduces the risk of potential post-operative infection even more. While cutting, ablating or coagulating tissue, the laser seals capillaries, small blood vessels, lymphatics, and nerve endings (i.e. it has hemostatic, antiedemic and analgesic effects). Sealed nerve endings mean more comfort for the patient after surgery, and sealed lymph nodes mean less swelling post-operatively. The surgeon can adjust the size and power of the laser beam to achieve the desired degree of control over the tissue removal process, and the laser is equally adept at incisions, excisions, and ablations.

Some have spent months preparing where they'll watch the total solar eclipse on Aug. 21, but many haven't considered how they'll safely view it.
To not risk permanent eye damage, solar eclipse glasses are necessary.
"Your retinas can get damaged by the sun's rays," College of Idaho Associate Professor of Physics Katie Devine said. "You may not actually even know it at the time it's happening. You may wake up the next morning and start seeing spots, so you can possible permanently damage your eyes by looking at a partial total eclipse."
Those viewing from the Treasure Valley need to keep eclipse glasses on during the entire duration of the event, but those in the path of totality have a small window of time when they can safely remove their glasses.
"During totality is the only time that it's safe to look at the eclipse without safety wear," Devine said.
Devine said you'll know when you're in that safe zone when none of the sun is visible and your view is totally dark.
If you already have eclipse glasses, check to make sure they're dark enough and meet the American Astronomical Society's safety suggestions. Your glasses should be labeled "ISO 12312-2".
"If you put your eyewear on and you can see anything through it, it's not dark enough," Devine said. "The only thing you should be able to see is the sun."
That means most of your homemade solutions, such as a pair of sunglasses, won't be enough to protect your eyes.
"The thing about eclipse glasses is they not only block the visible light, which is the stuff you can see, but they also block ultraviolet light," Devine said.
Parents can also make sure their children are protected by practicing safe viewing procedures.
Devine says you should look away from the eclipse during totality to remove your glasses and look down again before putting them back on. That way, you won't be tempted to remove them before totality is achieved.

These custom made filters allow photographers to take UV (blacklight) images using common flashes and a bit of black electric tape. These filters allow film speeds as low as 100 for close up work and exposure speeds as high as 1/400th of a second when used with higher ISOs.
A few points about these filters:
- Seconds are generally caused by errors in the kiln temperature or errors when applying the blacklight glass powder to the base. This creates filters that are thicker and block some UV light along with visible light. Oddly, it can also create tiny holes in the blacklight glass that enhances photos by adding a touch of visible light.
-High end flashes are not recommended as they generally have internal filters or coatings that absorb the UV light before it leaves the flash. These can be removed, but the cost is likely to be far higher than buying a basic off brand flash.
-The best way to mount the filter to your flash is to use black electric tape. Place the filter on the flash head and use four short strips about 1/16th of an inch over the edge of each filter to hold it to the flash and block any white light from existing the flash.. Then wrap a fifth strip around the head of the flash to finish the attachment.
-Absolute dark is not required to use these filters for most photo sessions. Enough ambient light to use your auto focus will generally not interfere with the black light exposure.
-Experimentation has shown us that the best starting setting seems to be 1/200 of a second at f6.3 and 400 ISO.
-TTL metering does not work with black light. You will need to experiment with manual settings.


SynergEyes contact lenses are hybrid contact lenses, or lenses made of both "hard" and "soft" materials. The outer rim of a SynergEyes contact lens (called the "soft skirt") offers all-day comfort and prevents debris from collecting under the lens. The inner area of the lens is rigid yet breathable, promoting eye health while providing clear, crisp vision for wearers with astigmatism, nearsightedness and farsightedness. SynergEyes contact lenses also address less common eye problems such as keratoconus, corneal ecstasia and pellucid marginal degeneration.
The rigid center of the lenses utilizes the natural layer of tears existing between the anterior surface of the eyeball lens and the cornea to neutralize blurry vision attributed to astigmatism. All-soft contact lenses cannot provide the kind of high-definition, crystal-clear vision provided by SynergEyes hybrid lenses. Complemented by the ability of the "soft skirt" to stabilize positioning of lenses on the eyes, SynergEyes is also the perfect vision solution for athletes who worry about their contact lenses becoming dislodged during rigorous activity. In addition, wearers of SynergEyes benefit from not dealing with "toric lens rotation", which causes blurring of vision in wearers of traditional hard or soft contact lenses.
Silicone hydrogel contact lenses allow beneficial amounts of oxygen to circulate through the lens and into the cornea, making SynergEyes the perfect choice for those who wear their contacts for long periods. All contact lenses contribute to a condition called hypoxia, or a significant reduction in oxygen supply to various parts of the body. When the cornea cannot access adequate levels of fresh oxygen, corneal swelling, reddened eyes, blurry vision and burning occurs, along with an increased risk of suffering eye infections.
Additional benefits of increased oxygen supply to the cornea include:
Initially, our eye doctor will recommend wearing your SynergEyes contact lenses for no more than six hours for the first four days and then eight hours on day five. If it feels like something is irritating your eyes while wearing SynergEyes contact lenses, always remove, clean and rinse the lens with appropriate solutions. At your follow-up visit, report any issues you may be having with the lenses to us. During this visit, we will evaluate the comfort level and fit of the lenses and examines your vision acuity as well.

Quality – These H10 LED’s feature 16 high power 5 watt CREE chips; Perfect for replacing your factory dull incandescent fog lamps in your car or truck, giving you 360 degrees of light. The LumaWerx™ LW80 is the brightest plug-and-play H10 LED bulb on the market today.
Bright – With a whopping 80 watts of output per bulb, these bulbs make excellent replacements to your factory fog lights. These bulbs are perfect to go into virtually any fog light housing because they produce very little heat with a crisp, pure white light output or amber which is great for fog lamp applications.
Ease – 100% plug-and-play; no splicing or cutting into your factory wiring harness. While producing a massive 80 watts of output and only drawing a fraction of a standard bulb, rest assured you wont be producing nearly as much heat so no worries about melting wiring or housings with these plug and play LED bulbs.
