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

Lily - I bought them and never used them. They are junk. You'd be way better off investing in a precision set of adjustable glasses like Superfocus.

These should fit over glasses and depending on your prescription, these do have separate focus adjustments.

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.

I wear glasses and have no problem with eye relief. I like the twist activated eyecup adjustment: when not actively using the binocs I keep them elevated to protect the ocular lenses. I don't believe in lens caps.

That's the method we used when buying my daughter's goggles. She ended up with -3.625 (R) and -4.25 (L) so we split the difference with a -4 prescription. She says they work well enough for her, and she has to be read a white board to get her workout during swim practice.

The larger lenses are dark green and are difficult to look through in poorly lit areas. The smaller ones areclear magnifiers. You can always change the lenses with any you might find or have cut thiugh that fit welders goggles.

Sorry, I can't help. They help my mother over her prescription reading glasses, but she does not have progressive lenses. Good luck. Great idea, Amazon!

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

Being sincere, I'm not sure if that prescription will fit on the glasses but mine are 1.85-1.65 and they do. You should consult a proffesional and ask him if it worth the risk because they change the way you do sports.

Try and buy one from Amazon that has a magnifier built in to the bottom half, they work great and are available in many optic strengths, the glasses are to close to your face, though at work we have glasses which do fit over regular glasses, hope this helps you, have a great and safe day.

I have bifocals too and they work fine for me. Haven't had a problem. They seem to fit over the lenses with enough room to spare. However, I think that would depend on the size or your prescription glasses. If they are larger in size, the goggles might cause the trouble you mentioned. Good luck. I bought 5 pairs of these.

This chart on the Bolle site is very helpful: http://www.bolle.com/technologies/goggles/

Pull the eye piece out at far as it will go. The dioptric is on the left hand side near the bottom of the eye piece. It's very small and hard to find and hard to to get your finger in there to make the adjustment.

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.

They do have a 2.5 and 3.0, but they are all bifocal. The upper part of the lenses are plain, no correction.

Typically, those that wear glasses need at least 15mm of eye relief in binoculars. Some mid-size binoculars will offer upwards of 19-20mm. Generally, the rule of thumb is more is better, as the eye cups are adjustable and able to fine tune better to fit/focus a wider range of glasses. Having a larger eye relief means that your view through the binoculars will not diminish because your eye is so far back from the viewing lens with glasses on. This particular model offer 16mm of eye relief which makes it a good choice for those that wear glasses. Good luck!
