If my regular glasses dose is -3.5 on the left and -3 on the right. What diopter should i get for the goggles?

i would get the -3 that way you don't cause disorientation, because water as is does have refraction, so i would go with the lowest diopter.

Honestly there isn't a big deal between -3.50 and -3.00 and you can get either one and you will see grate. But if you are still not satisfied go for 2 pairs of one -3.00 and -3.50 and just switch lenses and this way you have to pairs with perfect match

My daughter's prescription is -7.0 in one eye and -7.25 in the other. I purchased the -7.0 for her and they work great. For you I bet that the 9 would be better as you are already very nearly there at -8.75.

I usually just dip the whole goggle underwater, then shake the water off, lens will be decent enough, no misty. Good luck.

These have eye cups that twist and click out to 3 positions. The eye relief is 15mm, which is decent for most eyeglass wearers. I don't wear glasses and have the eye cups clicked all the way out. They are very comfortable and allow perfect viewing through the eyepiece lenses. There is, of course, a diopter adjustment if your eyes are not equal either.

You need to know your glasses prescription. If you're nearsighted, (need correction for distance sight your rx will be a negative number. The lenses come in 0.5 increments. For example I have a -3.75 correction. Since it is in between correction options I ordered a -3.50. (If your in between order the lesser strength). If you are far sighted the correction will be a +.(ie reading glasses). Hope that helps.

As it happens, I'm blind in my left eye. I've found these binoculars to be great. I don't know if one can adjust one side differently than the other, though.

Prescription glasses? I wear -8.5 correction (very nearsighted). The glasses are those small "reading glasses" style which are tough with this style of mask. To make the mask work properly you have to carefully fit the mask then adjust the glasses along the internal mask. The trick is to get the glasses to sit on the internal mask while adjusting them outside on your ears. Doing so I was able to get into an eighteen inch high crawlspace then laying on my side remove a dead groundhog that was a week and half decayed. I had no trouble with seal or seeing. I have to emphasize - you have to work with the internal mask and your glasses to make this function. It's not a "plug and play" operation. So, yes you can use this mask with prescription glasses but it's not a trivial process. When you get it right the mask works properly and you can see. No fogging either.

I have not had a problem with it. I think it depends on your style of shooting and placement of your weapon. I find these goggles not to hinder my field of vision.

I remove my glasses for all binoculars. I just adjust/focus the binoculars for what I need. These did well for my wife and I.

Actually, I normally wear trifocals. I use the monocular without my glasses, no problem. If I leave my glasses on I can't get my eye close enough to the eye piece.

When you snorkel, you wouldn't be using your bifocal lens. You should order the lens that you need for distance sight.

I would go down with a prescription because you would not want to feel dizzy because it is too powerful for your eyes. These did not work well for my daughter for competitive swim though. They leaked, just an FYI

Our advice if you're interested in something along these lines? Go to the Gunnar Optik site and create a pair of glasses with the features you want, and check out the price. Then go to a local optometrist and see if they can beat the price with the same set of features. Buy whichever is cheaper. If you cant afford either try the Gamma Rays

Hi JJ, I highly doubt that you could change these to prescription lenses... the goggles seem more like a cool toy rather than something of good quality.. Hope this helps :)

If you pull out the viewfinder you'll find a small dial. That's the diopter adjustment. It's great when you go from glasses to no glasses. Before you set it make sure you've actually had the camera properly focused on something first.

I use goggles that I also ordered from amazon.. There's quiet a but if space for upper face protection.. Most goggles (glasses would easily work) should work fine with these... The lower face protection is pretty big though (goes all the way behind your ears).. I'm 16 and I have to get it just right to play airsoft comfortably.

This is my secon d pair of glasses and they fit over my nose piece and are so very very helpful driving when it is dark and also during the day if it is gloomy. I have 2 sizes and they both are wonderful. I have tri focals and they are fine no problem with them at all.
