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

I don't wear glasses, but I used to (got lasik 5 years back and very happy with it!) So I'm very familiar with this problem. And yeah, I don't think these would seal with most glasses. Probably you should stick to the 2-part masks (safety glasses that fit over prescription glasses, plus a half-mask.) I know there also exist prescription safety goggles. My friend has some and he loves them. Depending on your prescription, they might be an option for you (I was too blind, so they didn't work for me.)

The 1.25, 1.50, 2.0, etc refers to the strength of the glasses----the "prescription strength". The higher the number, the stronger the prescription. Someone who only needs reading glasses might only require a 1.50. Someone who can't see well without glasses would require a higher number. I would suggest you go some where like a Dollar General store and try on several different strengths of their over the counter glasses so you will know what works best for you. As for the "size" of the glasses....they kind of telescope in and out in such a way that you can adjust their size by about 4" total. Doesn't sound like much, but that's enough to accommodate most people's head size. Hope this helps! The 1.25, 1.50, 2.0, etc refers to the strength of the glasses----the "prescription strength".

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

Yes, somebody here said +.2 or something like that.It is minor but present; makes screen seem just a little bit bigger.You can get them as prescription lenses if you need more.

I was looking at these and changed to a 10 x 50 Celestron " Up Close G2" . They were only $31.16 shipping a d i would by another pair tomorrow if need be. Crisp wide almost 3D vision. Check those out before spending your hard earned bucks.

That equation is correct... it is called spherical equivalent. With a -3.00 sphere and -3.25 cylinder, your spherical equivalent is -4.50. Keep in mind this will give you pretty decent vision - good enough to see at a reasonable distance, but this will not be equal to a full spectacle prescription. I am an optometrist.

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.

Her is two thoughts, 1st you can use a minus 1 and that may give you the rsange you want but I took the 2nd way which I purchased a -2, that way I can use the plus adjustment to get the proper adjust. Don't to purchase an eye cup for the corrective lens.

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!

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.

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 :)

Apologies for this late response. I wear glasses and have no trouble using these binocs. I would recommend them.

The goggles only come with a negative value which is for near-sighted. Mine were totally useless, terrible distortion, I could not use them and was given bad information by customer service. When I complained, iI was treated rudely. They offered no positive numbers for far-sighted

Depends on what your prescription is. The camera has a built in -3.0 to +1.0 diopter adjustment. You want to buy the one that will allow you to match your prescription. E.g. If you wear +2 prescription, get the +2 and dial it down by 1. You would only need the - if you have to go further than the -3 that is built in. However, I have found that I do not use the diopter. When I have my glasses off, the images on the LCD are blurry. So I shoot with my glasses or contacts, so I can still view the images on the LCD. Hope this helps you decide. Chris

If you have a DLP projector or Mitsubishi 3D TV(post 2010), the left/right polarity of the glasses can be adjusted by accessing the menu and accessing "3D Mode." There you will find your 3D options. I have a Mits 65738 and my settings are "automatic" - "standard" - "dlp-link" - they work perfectly.

You can choose between 60, 90 and 120 deg angles in the menu. Even the 120 isn't really fish eyed where as normal fish eye lenses distort around the edges. Hope this helps.
