Scientists made a prototype contact lens and glasses system that enables you to zoom in on a specific thing to 2.8 times magnification. The lenses perform the zooming, while the glasses allow you to shift between normal and magnified sight. At this time, the lens' technical engineers, a group with members from California and Switzerland, are developing it for those who have age related macular degeneration , which happens to be the number one reason for eyesight loss in Americans older than 60. The technical engineers are actually preparing to begin a clinical experiment in November, the BBC said.
The U.S. Defense Advanced Research Projects Agency (DARPA) funded the groundwork, recommending that the U.S. government is eying super vision of soldiers in the near future. But, it really must be better to create something for macular degeneration first, since it's better to come up with a possible remedy for eyesight loss compared to it is to improve on healthy eyesight, the BBC said. The lens is composed of concentric regions. The center region allows light through normally, for regular eyesight. Whereas, the corners of the lens are purposely designed to reflect light as well as magnify it. The final lens is 1.17 millimeters at the thickest region around the corners and it's manufactured from the similar hard plastic as first-generation contact lenses, the technical engineers explained in a paper they published in the journal Optics Express.
The glasses function by adding or taking out a polarized light filter onto their lenses. With the filter on, light would travel to the normal region of the lens. Without the filter, light would go to the magnifying region rather.

Optics are a universal attachment in Call of Duty: Modern Warfare 2. This means that once you unlock an optic, it will be available for use on every other gun in the game, except for Launcher and Melee weapons, of course. Out of the wide selection of optics present in Modern Warfare 2, we have listed the best ones for all ranges that you need to unlock first.
Best Optics to use in Call of Duty Modern Warfare 2
Cronen Mini Pro
This is a perfect optic for close-quarters combat that you can equip on an AR, SMG, Handgun, or any other weapon of your choice. While there are several other close-range scopes in the game, the blue-dot Cronen Mini Pro offers the cleanest view of all. Other good alternatives are the SZ Sigma-IV yellow dot optic and the Cronen Mini Red Dot.
DF105 Reflex Sight
This red-dot optic offers a clear vision similar to the Cronen Mini Pro but with a slightly bigger magnification than the latter.
The Schlager 4x is a 3.4x zoom optic that you can use on your ARs for mid to long-range engagements.
VLK 4.0 Optic
The iconic VLK optic offers a slightly larger magnification of 4x but has thicker bezels than the Schlager scope.
FORGE TAC Delta 4
Moving on to the larger zoom optics for Marksman Rifles and Sniper Rifles, the first on our list is the FORGE TAC Delta 4. This optic offers a 5.5x magnification and an immensely clean reticle.
Luca Bandera Scope
This is a clean, hybrid optic offering 3.7x and 8x zoom levels, which you can switch between. One downside of this optic is that there are no mildots on the crosshairs, which makes it comparatively difficult to adjust for bullet drop.
SP-X 80 6.6x
The SP-X 80 is the perfect long-range Sniper Rifle scope with a clutter-free reticle and mildots that you can utilize to study the bullet drop if necessary. This optic is togglable between 6.6x and 11x magnification.
FTAC Locus SP
A great competitor to the SP-X 80 optic, the FTAC Locus SP offers 7x and 11x zoom levels. Since the magnification on both these optics is very similar, you can choose between them depending on which reticle you prefer more.
Finally, the Drexsom Prime-90 is a great Sniper scope for players who like to use a thermal optic. It offers 7.5x magnification and is one of the cleanest thermal scopes in MW2.
Stay tuned to Pro Game Guides for more Call of Duty: Modern Warfare 2 content. In the meantime, head over to our article on How to unlock all MCPR-300 Attachments in MW2.

The position of a point in space can be computed from two views using triangulation:
Of course, to get a reasonably accurate 3D reconstruction (modulo scale) we need the parameters of the stereo pair (focal lengths and relative position and orientation of the cameras). Otherwise the estimated 3D points may suffer unacceptable projective deformation.
One of the most wonderful results of multiview geometry is that the calibration parameters can be inferred automatically just from the views of a small number of arbitrary 3D points (in unknown positions).
The easyVision example program "demostereo" illustrates this idea using two webcams. The interest point can be detected by a simple heuristic on the hsv color space. And a good estimation of position and velocity is obtained by a Kalman filter. First we adjust the parameters of the region detector and check that the tracker works:
If the point "stops", it is stored. When the set of points produces a promising estimation of the stereo geometry, the camera parameters are updated in the 3D view:
Subsequent estimations should be progressively closer to a similar reconstruction.
Now we can register points in the desired positions. For example, here we mark something like a box:
Note that auto-calibration from a single fundamental matrix is possible here because the camera model has only one internal unknown parameter, the focal distance.
This program shows in a very attractive way the basis of stereo vision. And this kind of 3D point capture method can also be useful in some applications.


Shooting doesn’t always happen in perfect lighting conditions, especially if you’re a big game hunter. To make an ethical shot on an animal when the sun is beginning to rise, or just about to set, takes a special kind of scope. After all, you can’t hit what you can’t see.
The best low light scope will provide bright, clear images, even when the sun begins to fade. However, knowing which scope to choose can be hard, especially when you’re shopping under the bright fluorescent lights of a showroom floor.

What Makes a Good Low Light Scope?
When it comes to low light performance, not all scopes are created equal. Here are a few key features that help some scopes seem brighter in murky light.
The job of the objective lens is to let light into the scope. It works in much the same way that a window lets light into a room. Generally speaking, a room with larger windows will be brighter than one with small windows. The same is true of a scope with a larger objective lens. In the world of riflescopes, the larger the objective lens, the brighter the images will be (usually).
However, the objective lens doesn’t do all that work alone. Other features come into play that help the objective lens do its job. A scope with a small 44mm objective may be brighter than one with a massive 55mm objective lens, especially if that smaller scope is made with premium glass and multiple anti-reflective coatings.
A massive objective lens can be a hindrance in the field. A riflescope with a large objective lens will be heavy and bulky, which can be a major hindrance when hunting thick woods or remote backcountry locations. The key to successful shooting is to choose a scope with an objective lens that is large enough to provide a bright sight picture, but not so large that it inhibits your ability to move in the woods.
Anti-reflection coatings work like magic when it comes to brightness. The right coatings can almost double the scope’s brightness, and unlike large objective lenses, lens coatings add zero weight or bulk to your optic.
These thin coatings are made from rare earth minerals and reduce reflection through wave phase cancellation. If that sounds complicated and “science-y” that’s because it is.
Here is a basic explanation of how anti-reflective coatings work for us non-sciency shooters.
When light hits glass, only about 96 percent of it passes through. The other 4 percent gets bounced around off the surface. While 4 percent may not sound like a whole lot, consider the fact that some scopes have 6 to 10 glass lenses. You lose at least 4 percent each time the light hits a piece of glass. It doesn’t take a mathematical genius to realize you can lose a lot of light as it makes its way through those glass surfaces before it reaches your eye.
Each layer of anti-reflective coating can cut the amount of light that bounces off the glass by half. Multiple layers can reduce reflective light loss to less than 1/10th of a percent. For the best low light performance, you’ll want an optic with fully multi-coated lenses.
Higher magnification levels can make a scope appear brighter. When you look at a distant object through a scope, the magnified image will appear brighter than it does when you look at it with the naked eye. However, this isn’t the scope working magic. If you moved closer to an object in dim light, it would naturally appear brighter due to your physical proximity. The scope works the same way by taking you visually closer to the object rather than physically closer.

UV light is a very common culprit in degradation of plastics as these photons have enough energy to cause problems if they are absorbed by the polymer. E = h c/l so shorter wavelengths have higher energy. So the shorter the wavelength, the better, right?
Unfortunately this is also not correct for two reasons. First, the shorter wavelengths become increasingly rarer on the surface of the earth thanks to all the ozone up high. So going with lots of really short wavelength is unrealistic. But secondly, different plastics react differently to the spectra. A plot of degradation rate vs. wavelength will show a peak and it is seldom at the shortest wavelengths. This plot is known as the activation spectra (see Andrady's article for a good review) and is key to running good tests. Polypropylene for example, has a peak at about 350 nm, much higher than other plastics.
UPDATE: The formula for energy has been corrected. I was so excited to get the HTML right that I ignored the content.

Modern lasers are better in speed and accuracy than older ones, so results are far superior than the early years of refractive surgery (1990-2000). We currently use the state-of-the-art Concerto (Wavelight) excimer laser, which is one of the fastest and most modern laser available worldwide. With high frequency (500Hz) and excellent eye-movement tracker, it has unparalleled results even in high amounts of refractive errors.
What are refractive errors?
In myopia (short-sightness), incoming rays of light are focused in front of the retina (the sensitive layer inside the eye like the film in the camera), resulting in dim vision for distance without glasses or contact lenses. In hyperopia (long-sightness), incoming rays of light are focused behind the retina, resulting in dim vision for near and frequently for distance, depending on the amount of error. In astigmatism the cornea (the surface transparent layer of the eye) has unequal curvatures (instead of being like a football, it rather has the form of a rugby ball) resulting in dim vision in all distances. In all kinds of laser refractive surgery, the excimer laser is used to reshape the surface of the eye (the cornea), in order to eliminate any refractive error, so that vision is clear without glasses or contact lenses.
There are three main conditions to be met if you are considering refractive surgery:
Which are the options in laser refractive surgery?
In ASA (advanced surface ablation) the surgery is carried on the surface of the cornea. Initially the superficial layer (epithelium) is removed without any cutting (rather lifting) and then the laser is applied. The main difference between ASA and LASIK is that in ASA there is no cut on the cornea but the refractive laser is the same. Problems previously related with surface techniques (regression, haze, pain) are usually no longer an issue with advanced surface ablation.
In LASIK (laser in situ keratomileusis) the surgery is carried on approximately in 1/4 the depth of the cornea. Initially a femtosecond laser cuts a thin superficial flap (like a laser blade). Then the flap is lifted and the excimer laser is applied on the cornea. The thin flap is repositioned at the end of the treatment and stays in place without any sutures.
The choice of the method of refractive surgery depends on the amount of the refractive error, the thickness of the cornea and personal preference. In LASIK there is faster visual rehabilitation and less pain, whereas in ASA there is some pain for the first two days and fluctuation of vision for a few days, mainly because of the time for the surface to heal (a special contact lens is used for three days). On the other hand in ASA there is no cut on the cornea. Eventually both techniques have comparable long term results as shown in large studies. Dr George Kampougeris will discuss the appropriate technique for you during your consultation.
In monovision one eye is corrected to zero and the other is left slightly myopic in purpose (-1 or -1.5). Thus the brain subconsciously uses one eye for distance and the other eye for near (the low myopic eye). It is a good choice for people who dislike wearing presbyopic glasses after the age of 45. Not all people are suitable for monovision. There is a special test for monovision success, which will be done during your consultation.

Macular degeneration is a common eye disease among elderly people. When people have macular degeneration, they will have some loss in their central vision. So the most important thing to do is to find out the way to save their existing vision. Macular degeneration will offer the very help they need. The following will give some introduction on macular degeneration devices in order to help people to benefit more from them.
When people are at their 40's or 50's, the macula, which is located in the center of the retina and in charge of the detail vision, will become weak. Therefore, people will have difficult in reading, playing cards, driving or other daily tasks. If macular degeneration is not treated in time, there will be more vision loss. Macular degeneration devices are used to maximize people's remaining vision by the use of specially designed eyeglasses, computer programs and other technologies. With the help of those macular degeneration devices, people's low vision can be improved to some extent, and they are able to enjoy reading or some daily tasks.
Bifocal reading glass is one of macular degeneration devices. With the help of bifocal reading glasses, people can see clearly no matter far away or close up as this kind of glass can change people's vision field. Therefore, bifocal reading glasses are very popular among aged people worldwide.
Do you know there will be miniature telescopes on the eyeglass lenses? Yes, a miniature telescope can be placed behind or on top of the lens, so in this way, people can have two options. One is to look through the regular lens and benefit from the eye glass prescription, the other is to look through the telescopic lens to see detailed information clearly as there is an ultra magnification.
And for people who have macular degeneration but need to use computers, they can have specially designed monitor for help, as the monitor can magnify the front size and enable people to see clearly. Besides, there is also software for macular degeneration devices, which can transfer our sound into text. We can speak to the computer microphone, and then the sound will be transferred into text on the screen. Moreover, even people with no vision, they can also benefit from the program which can turn the test into Braille documents online.
Closed circuit television is also proved to be an effective macular degeneration device. We can put the right page under camera, and then the image will appear on our television screen, so that people can read and see them clearly.
Thanks for the great help given by macular degeneration devices. No matter what need you have caused by low vision due to macular degeneration, you can always find a satisfied macular degeneration device to satisfy your needs.


Definition of Contact Image Sensor
A Contact Image Sensor (CIS) is a type of semiconductor-based image sensor used predominantly in scanning devices, such as document and barcode scanners. CIS technology consists of a compact, energy-efficient linear array of light-sensitive elements or photodiodes that detect the reflected light from an object being scanned. As the object is placed in close proximity to the CIS, it ensures high-resolution, sharp images with minimal aberrations.
The phonetics of the keyword “Contact Image Sensor” can be represented as:/ˈkɒn.tækt ˈɪm.ɪdʒ ˈsɛn.sər/In the International Phonetic Alphabet (IPA), where:- /ˈkɒn.tækt/ represents “contact”- /ˈɪm.ɪdʒ/ represents “image”- /ˈsɛn.sər/ represents “sensor”
- Contact Image Sensors (CIS) are compact and low-cost sensors that offer high-resolution scanning for document and image processing.
- CIS technology uses an array of Red, Green, and Blue (RGB) LEDs for illumination, providing better color reproduction while consuming less energy compared to traditional CCD sensors.
- Due to their small size, CIS modules are commonly integrated into portable devices such as scanners, copiers, and multifunction printers, contributing to a compact and lightweight design.
Importance of Contact Image Sensor
Contact Image Sensor (CIS) is a vital technology term in the world of imaging and scanning, as it refers to a type of sensor that captures an object’s image effectively by being in direct contact or extremely close proximity to it.
Boasting a compact structure and lower power consumption compared to its counterparts such as CCD or CMOS sensors, CIS technology has been widely adopted in various applications such as document scanners, barcode readers, and copiers.
Its significance lies in its ability to deliver high-quality images without distortion, while leveraging its small form factor, which enables the development of portable and space-efficient devices.
In summary, the importance of the Contact Image Sensor is underscored by its unique features that contribute to the performance, reliability, and practicality of numerous imaging and scanning products.
A Contact Image Sensor (CIS) is a crucial component in modern imaging technology, primarily used in scanning devices such as flatbed scanners, barcode scanners, and multifunctional printers. The purpose of a CIS is to convert optical information from a document or object into digital data, allowing for easy storage, manipulation, and transmission of images. This technology is employed for various applications, ranging from document scanning in an office environment to identifying product information in retail settings.
In essence, the Contact Image Sensor has transformed the way we interact with physical documents, enabling efficient digitalization and streamlining of work processes. To achieve this, the Contact Image Sensor utilizes an array of microscopic light sensors, which are carefully positioned in close proximity to the surface being scanned. These sensors are highly sensitive to light and are able to capture even the smallest variations in color, contrast, and shape in the scanned object.
As the scanning device moves along the surface, the CIS records the incoming light from the object and converts it into electrical signals, accurately preserving the original image’s details. By employing sophisticated image processing algorithms, the digital data gathered by the CIS can be further refined and optimized to reflect the highest possible image quality. Ultimately, the Contact Image Sensor has emerged as an indispensable element of modern imaging technology, offering unparalleled precision and accuracy in capturing and processing visual information.
Examples of Contact Image Sensor
Contact Image Sensors (CIS) are widely used in various real-world applications due to their compact size, low power consumption, and ability to capture high-resolution images. Here are three real-world examples of Contact Image Sensor technology:
Scanners: CIS technology is commonly utilized in flatbed scanners, portable document scanners, and all-in-one printers. They are positioned right below the surface of the scanning glass and generate digital images from scanned documents, photos, or objects. The LED lights in these scanners provide illumination, while the CIS array captures the reflected light to create a digital image.
Bar Code Readers: Handheld and stationary barcode readers often employ CIS technology for scanning barcodes on various items, products, or documents. These barcode readers use a combination of LEDs and CIS arrays to capture the barcode pattern, which is then decoded by the device’s internal software to retrieve the information stored in the code.
Sheet-fed scanners: Many sheet-fed scanners use Contact Image Sensors for fast, high-resolution document scanning. These scanners automatically pull documents one at a time through the scanning mechanism, where the CIS array captures images as the document moves past it. They are especially useful in busy office environments, where large volumes of documents need to be converted to a digital format.
Contact Image Sensor FAQ
What is a Contact Image Sensor (CIS)?
A Contact Image Sensor (CIS) is an imaging device commonly used in scanners, copiers, and other imaging equipment. It consists of an array of photodiodes and light-emitting diodes (LEDs) positioned in close proximity to the object being scanned, resulting in high-quality, clear image reproduction with minimal distortion.
How does a Contact Image Sensor work?
A CIS works by using an array of photodiodes and LEDs to scan the surface of an object, typically a document, line by line. The LEDs emit light, illuminating the object, and the photodiodes then capture the reflected light to create a digital image. The image data is then transferred to a processing unit, which converts it into a digital format for storage, display, or transmission.
What are the advantages of using a Contact Image Sensor over other imaging devices?
Contact Image Sensors have several advantages over other imaging devices, such as Charge-Coupled Devices (CCDs). Some of the key benefits include a smaller form factor, lower power consumption, and reduced manufacturing costs. CIS technology also usually results in better image quality in terms of geometric distortion and optical aberrations, as the sensors are placed directly in contact with the document being scanned.
What are the main applications of Contact Image Sensors?
Contact Image Sensors are commonly used in several imaging applications, including document scanners, flatbed scanners, facsimile machines (fax), copiers, barcode readers, and some digital cameras. They are particularly well-suited for portable and low-power devices due to their small size and energy efficiency.
How can a Contact Image Sensor’s image quality be improved?
The image quality of a Contact Image Sensor can be improved by using high-quality photodiodes and LEDs, as well as by optimizing the sensor’s design, such as the positioning of the diodes and LEDs. Additionally, the performance of a CIS can be enhanced by using image processing algorithms to correct for distortion and noise that may be introduced during the scanning process.

The leading edge for 300,000 years of human vision technology
Traditional vision testing uses black and white static images. It fails to account for the fact that acuity is actually a matrix response of the Red, Green, and Blue cone photoreceptors in your eyes. The retinal neural ganglia function as biological circuit board, and are chromatically sensitive to light to stabilize, and emphasize, seeing red at far distances and green at near distances. Static-letter black and white image testing fails to account for Red-Focused Chromatic Vision (RFCV) and its related near-vision symptoms affecting acuity such as dyslexia, migraines, and other chromatic-responsive visual problems.
There are 100 cone (color perceiving) photoreceptors for every optic nerve fiber. The neural layers of the retina “process” the responses of the photoreceptors much like a circuit board with the emphasis on patterns of motion and proximity. Those neural ganglia are also chromatically sensitive and emphasize seeing red at distances and green for near vision.
ViewChroma™ lenses restore chromatic balance to overcome the symptoms inherent in Red-Focused Chromatic Vision (RFCV).

3D Scanning / Photogrammetry
3D scanning involves collecting overlapping high-resolution still images processed by powerful computers using a method called photogrammetry. The result is a 3D model with a level of detail far superior to other documentation methods such as Multi Beam Echo Sounder (MBES) and Side Scan Sonar (SSS). The 3D model can be viewed from any angle or view, which offers an outstanding overview and basis for assessments.
Ocean Discovery is today a leader in 3D scanning and underwater photogrammetry. Initially, the method was mainly used in marine archaeology. The most famous marine archaeological documentation carried out by the company is the Mars shipwreck , which sank in a naval battle off Öland in 1564. Nowadays, the method is used in a variety of applications and since 2018 the company has scanned 6 wrecks for the Swedish Maritime and Water Authority in the work to document and clean up environmentally hazardous wrecks. 3D scanning is also used for port inspections, bridge foundations, pipelines and all sorts of underwater constructions.
Ocean Discovery uses exclusively remotely control underwater robots (ROV) equipped with advanced still cameras and powerful strobes. This means cost-effectiveness and is safer than using divers. The ROV can operate down to a depth of 500m and together with survey vessels with dynamic positioning, the ROV can operate without anchoring.
3D scanning opens up new opportunities in disaster investigations and marine archaeology where the new technology can provide an overall picture of the entire wreck site as well as detailed studies of damage and technical details with the possibility of precise measurement within a few millimeters margin.
Ocean Discovery also produces computer-generated images (CGI) based on photogrammetry to media, museums and the film industry.
ROV with high resolution camera for photogrammetry
Orthographic images are a composite image in bird's eye view of all images that created the 3D model. Depending on the size of the project, it can be thousands of images that together form a single ultra-high-resolution image. The images can be generated in GeoTiff format so they can be opened in GIS programs where measurements and evaluations can be performed. With the help of underwater positioning equipment (USBL), the orthographic image can also be referenced geographically, thus it is possible to position each point in the image.
Detailed elevation maps
Detailed elevation maps (DEM) mean that each point in the image is assigned a color depending on the depth. The result is an image where every small difference in height is clearly visible and you get an immediate overview. DEM image can be opened in on the market available GIS programs.
3D Scanning of ports and submerged pipes
3D scanning is useful as an inspection method for all kinds of underwater structures. During port inspections, the sheet piling can be inspected quickly and efficiently and damage measured, assessed and positioned. The position of submerged pipes, and displaced weights with free span as a result can be accurately measured in the 3D image. The examinations can be supplemented with thickness measurement with ultrasound.


Have you ever walked into a restaurant with super bright lighting and felt that the space felt "off"? If the answer is yes, you aren't wrong! To first understand why this feeling occurs, let's understand the basics of what light temperature is.
So what is color temperature anyway?
As a review, color temperature (Correlated Color Temperature, or CCT, in lighting tech jargon) is essentially a gauge of how yellow or blue the color of light emitted from a light bulb appears.
It’s measured in the Kelvin unit. Most light temperatures are found between 2200 (warm light) Kelvin degrees and 6500 (cool light) Kelvin degrees.
Warm light sources, such as incandescent bulbs, have a low color temperature (2200-3000K) and feature more light in the red/ orange/ yellow range.
When you think of a warm color temperature, think of the warm, inviting light of a fire in the fireplace or a nice high-end restaurant with classy dim lighting.
Cool light sources, such as some HID or fluorescent lamps, have a high color temperature (>4000K) and feature more light in the blue range.
When you think of a cool color temperature, think of the crisp white or blue light of school hallways or hospitals.
Affects on Productivity
Recent studies looked at the effect of color temperature on visual acuity in schoolchildren.
Optometrists conducted vision and reading tests for children under 3 different scenarios:
SS00K (white) light at normal light level
3500K (warm white) light at normal light level
SS00K light at half the level of the first two scenarios.

Glass has this wonderful ability of being able to alter things. Solely by changing the thickness of the glass different optical phenomena and optical effects occur. The piece 'World upside down' show convergence through a convex lens. The term convex denotes a surface like the outside of a ball or sphere and convergence is the bending of light rays towards each other by a convex lens. Both the lens and the window should be made of the same type of glass to ensure the same coefficient of thermal expansion.
World upside down
When looking at this picture at least three convex lenses are involved. In the human eye (1), in the glass (2), and in the camera (3) that captured the photo. They all have the ability to turn the world upside down. Images of the world, as we see it (provided no extra lens is involved) enter the human eye inverted. In a camera the images are also captured upside down on the film, and when using a large format camera the photographer even previews the images inverted. That the images are captured upside down on the film does not matter; nothing could be easier than turning a negative. The lens in my glass piece below works accordingly. We humans have an advantage; our brain turns the images around for us. In my piece, the centre image actually hits the retina (the light-sensitive tissue lining the inner surface of the eye) right side up. In this case, it is the viewer's brain that turns the world up side down.

Night Vision Infrared Stealth Binoculars
Spynet surveillance goggles
Spy toys get more advanced as technology moves from the secret military sector into civilian uses. With these night vision binoculars, the aspiring spy or detective can utilize infrared surveillance technology to see up to fifty feet in total darkness. The system requires batteries as infrared light is sent into the space, which sensors in the goggles then pick up and transmit to the eyes and visual information. It is a full binocular display allowing both eyes to work together with the technology to see at night.
Evolution of Night Vision Binoculars
The development of night vision binoculars can be traced back to the mid-20th century, closely tied to military applications during and after World War II. Initial night vision devices were large, cumbersome, and required an external infrared light source to illuminate targets. These first-generation devices, although revolutionary at the time, had limited range and resolution.
By the 1970s, the technology had advanced to the second generation, featuring the Micro Channel Plate (MCP) for the first time. MCPs amplified the available light more efficiently, enabling a more crisp and bright image, without the need for external infrared illuminators. These binoculars became smaller, more effective, and began to find applications beyond the military, such as in wildlife observation and law enforcement.
Third-generation night vision binoculars, which emerged in the 1990s, introduced gallium arsenide for photocathodes, offering even better resolution and sensitivity. These high-performance devices could work in extremely low-light conditions and offered excellent image quality.
The fourth and current generation removed the ion film barrier from the MCP, increasing the life of the device and providing an even clearer image. These units are not only used by elite military forces but have become increasingly popular for civilian use, including hunting, wildlife observation, and even astronomy.
Civilian Use and Technological Innovations
As the technology became more accessible and affordable, night vision binoculars started becoming popular among civilians for various applications. Today, innovations continue with the integration of digital displays, recording capabilities, and even WiFi for real-time sharing.
The journey of night vision binoculars from bulky, military-only equipment to compact, highly-efficient devices accessible to the general public is a testament to the rapid advancements in optics and electronics.


Nothing beats a fishing escapade in the sunset or on a hot sunny afternoon. However, despite the perfect weather, you are likely to experience vision problems due to the light reflection on the water. That is why we recommend having a pair of sunglasses and, to be clear, polarized glasses. Costa 580g and 580p glasses are made for all outdoor activities. This way, you can be assured that you will not miss a single catch due to blurred vision. In this article, we will be differentiating the two lenses, so you have an easy time choosing and making a purchasing decision.
More About Costa 580g
Costa 580g lenses were designed for people who are always outdoor. Eyes require much protection, and sometimes sunglasses do not meet our requirements. This is where Costa580 glass lenses come in. They are highly durable due to their nylon construction and rust-resistant hinges.
They manage light by offering protection against ultraviolet light and absorbing HEV light known to cause degeneration, cataracts, and other eye problems. Additionally, they block the harsh yellow light to help boost the amount of greens, blues and reds.
The lenses are scratch-resistant owing to the C-WALL molecular bond. Moreover, they are 20% thinner and 22% lighter than polarized glasses, making them the lightest and most durable lenses. They are perfect for anyone as they come with a rectangular frame to fit any face shape plus, they provide sufficient airflow preventing excessive sweating.
- Filter out harsh yellow light
- They are light
- Sits securely on your head
- Provides clear vision
- Comfortable frame
- With dim light, the lenses create a double vision
- The rubber on the glass is not very durable
More About Costa 580P
Costa 580p sunglasses, just like 580g, do not compromise on quality and durability. P stands for polycarbonate and is meant to provide a high clarity so you can enjoy your time in open waters and offshore. They are made with a bio-based nylon frame material that is durable, tough, and comfortable.
The lenses provide ultralight protection and absorb the harmful HEV light. They are lightweight so that you can wear them all day, and they come with an encapsulated mirror between the glass layers that makes them scratch-resistant. To ensure their safety, they come with a costa case cleaning cloth. Additionally, they offer a limited warranty so you can have them repaired by professionals in the possibility of damages.
- Carry case for increased safety
- Durable materials
- Frame blocks light from the side
- The lens is excellent at blocking light
- Feel comfortable
- The frames are thinner than previous models
- The lenses feel small for some users
Costa 580g vs. 580p : What’s the Difference
Costa 580g and 580p are some of the best lenses you can get for your fishing escapades. They are durable, comfortable, and effectively protect your eyes from excess light. However, the two vary slightly, and here we are going to be looking at their differences.
The first difference is in the lens material. Costa 580g consists of glass lenses, while Costa 580p consists of plastic lenses.
Due to their difference in lens materials, Costa 580g is less prone to scratches as it’s made of glass. However, it is more likely to break it handled recklessly. On the contrary, Costa 580p has plastic lenses; hence it’s likely to get scratches but less likely to face breakages.
Costa 580p lenses are light due to the plastic material. On the other hand, Costa 5890g lenses are a little heavier due to the glass material.
Costa 580g lenses have an encapsulated mirror between their glass layers, making them scratchproof. On the other hand, Costa 580p lenses only come with a C-Wall molecular bond for increased scratch resistance.
Costa 580g vs. 580p : Head to Head Comparison Table
It doesn’t matter whether you are going out surfing, fishing, or kayaking. Owning Costa lenses will help keep your eyes safe. However, choosing between Costa 580g and Costa 580p can be confusing. Firstly, we understand that these lenses are made for all your outdoor activities with the utmost expertise. However, between the two, I would go for Costa 580g since I prefer glass more as it’s less prone to scratches and the comfort that comes with these products. However, this does not mean Costa 580p lenses are any bad. The Costa 580p best suits people who prefer plastic and lighter lenses.
