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

The glasses can be used for Driving.However the Diopters range is set at-3.0 to + 6.0 perhaps the strength you require is stronger than the range of the Diopters set for these glasses

This is a very complicated answer. I defer to this link.http://www.astroadventures.net/cohen/articles/Wear%20or%20Not%20to%20Wear%20Glasses.pdfWhether you wear glasses or not, each lens that you use requires that your eye be placed at an optimum distance from the lens. Wearing glasses prohibits one from getting one's eye close enough to enjoy the full field of view with some lenses but not others. The preferred method is to NOT wear glasses and each person must adjust the focus for the best clarity. If your wife has an astigmatism, you can switch to higher eye relief lens while wearing glasses or purchase Televue Dioptrx Astigmatism-Correcting Lenses while not wearing glasses.

Because of the difference I would suggest buying 1 pair in each of the diopters you need and swapping out the lenses. For me the difference was only 1 point so I went up a half. They've worked out great.

Actually the claimed eye relief is 17.5, which I find just about totally adequate for my use with glasses. So long as I take care and don't let them move around on my lenses, I can see the full field of view, which I haven't come close to seeing with any other optics in my life.

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 :)

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.

Go higher! under water there is less visibility, so anything that gives you the edge, I would go for... Anyway there is some eye adjustment at any point and at that level half a Dioptric is almost negligible (my unprofessional opinion)

Sorry, our lens only adjust single vision. If it is for snorkeling, bifocal/reader lenses are not necessary.

It depends on what your eyeglass prescription is. I spoke to my optometrist to see Whart general range is.

Nancy - Regarding using these for driving: While you may be able to dial in your correct number (in diopters, assuming it's -6 or less) the peripheral vision is limited. For this reason, if using for driving, you'd need to turn your head rather than your eyes, to see thing not directly in front of you. This is most likely the reason they're not recommended for driving. A safety risk . . . Hope this helps!

David, these glasses are 1.25x magnification. OPTX 20/20 does offer other magnifications if this isn't what you're looking for.

Yes - this pair allows for diopter adjustments, which you calibrate when you first use them out of the box (it may make focusing difficult for other eyes than your own, like when you lend your binos to someone else). I think the paperwork included has directions, and if not you can google how to do it :)

You just need to know what your basic prescription u s and order a lens close to that. It worked for me as nd I am very nearsighted.

I wear trifocals and the single lens correction worked just fine. I wasn't close enough to need the extra correction even when I was about 3 feet away.

These binoculars have a rather short eye relief distance. You can roll down the eye cup to compensate for this. Using with glasses might dimenish the field of view. If your vision is not too bad and relatively close in each eye, you should be able to use without glasses by focusing the left eye with the center focus wheel and using the diopter setting on the right lense to focus the right eye. If there is sporting goods store near, you might be able to find a pair to "test drive". It will be hard to beat Amazon's price. Hope this helps.

My son had the same issue. I bought one pair of each prescription and then took the pairs apart when they arrived to make two pairs of swim goggles for him. Worked great! I marked the higher prescription side with a dot of sharpy so he would know which way to put them on each time.
