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.

They are adult size with different nose pieces to make a more custom size. If you mean correction strength ask your eye doctor. My son is nearsighted, he needs a negative correction I got him -2.0

I wondered the same thing. Even called Speedo directly and they said they had no idea what AC was. My child really wanted the rainbow goggles which only came in size AC, so I took a chance and ordered them. They are the same as One Size. I also ordered a second pair that was listed as One Size. It does say AC on both labels. I will post photos.

Thank you. I have '80s size glasses. If goggles fit, then these should fit too.

The goggles are definitely REGULAR fit (not SMALL fit) as they were purchased for my husband (he is 6 ft. and 235 pounds) and they fit him well. Hope this helps.

You must measure the scope eyepiece diameter with a caliper or micrometer, the order the right size cover on Amazon. Do the same for the other end of the scope, if you need that cover also. The inside diameter of each cover will be shown on the page. Do not order a smaller one as it cannot be stretched to fit a large diameter scope.

measure the eye piece with a tape. measure then look up what kind of cover you want they use the numbers for the different size of eye piece.

look for the size of a particular glass in the product description (on Amazon of course). you will see numbers like this 55-18-14555(mm) will represent the lens width18(mm) will represent the bridge width145(mm) will represent the overall length of the armthese numbers change with the models - GR003, 004, and 001, etc. I took a pair of sunglasses that fit me well on the brigde of my nose and the arms length and measured them. Prescription glasses may have the measurements on the arms already. Google how to properly measure for glass frames and then find your match of Gamma Ray. The Gr001-C1 matched mine, although I think I got the bridge a mm larger just in case. look for the size of a particular glass in the product description (on Amazon of course). you will see numbers like this 55-18-14555(mm) will represent the lens width18(mm) will represent the bridge width145(mm) will represent the overall length of the armthese numbers change with the models - GR003, 004, and 001, etc. I took a pair of sunglasses that fit me well on the brigde of my nose and the arms length and measured them.

You most likely want to get them junior size goggles. We think these would most likely be too big for them.

Take a flexible measuring tape and measure around the palm of your hand, just inside the web of your thumb. That's how I did it and it fit perfectly.

Like you, I don't know what the difference is. I can tell you that my measurement is 21 1/4 " circumference where the goggles fit and these goggles fit just fine. I have a small head these goggles fit me just fine. I hope this helps..

Style of glasses and size - I can't tell you exactly, but visit a store where there is a display, hold your glasses against the display and you will find the recommended size/style for your prescription glasses.
