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

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.

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

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.

Yes, there is a diopter adjustment that works quite well. I use reading 2+ reading glasses and with the adjustment the EVF image is perfectly clear.

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.

I would buy the Aqua Sphere Eagle glasses. You buy the goggles with clear lenses and then order the corrective lenses needed for each eye. You pop out the clear lenses and then pop in the corrective lenses. They work great. Check it out on Amazon.

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.)

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

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.

Contact Splaqua. I have a smaller deviation in my correction , and in this situation it is suggested to go with the lower number. I know that Splaqua, and probably others, will help with getting the proper correction for each eye in circumstances that call for it.

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.

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.

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.

There's no diopter adjustment so make sure your eyes are a normal 20/20 vision.

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

goggles dont come in sizes but in styles. Its wathever feel more conmfortable to you, the adjustment is done thru the strap. If you are talking about prescription it is usually what your glasses prescription is if its different on both eyes go with the lowest prescription. otherwise you will feel disoriented.
