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

look for the size of a particular glass in the product description (on Amazon of course). you will see numbers like this 55-18-145 55(mm) will represent the lens width 18(mm) will represent the bridge width 145(mm) will represent the overall length of the arm these 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.

I purchased these last year and they are great! i recommend upgrading the memory card as it fills up quick!. As far as the size, I'd say they are standard adult goggles. I wore the 1 size fits all Scotts before this and they fit about the same.

Measure or look up the outside diameter of your scope. Then look up your size on this Butler chart. http://www.butler-creek.com/productsImages/charts/flip_scope_chart.html

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.

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.

I am not sure, but I would hesitate to buy something untried when one has either a smaller or a larger fit than is standard for such things. Obviously, one can tighten the strap. I have a big head and wide face and they fit me and my eyeglasses well. So with that perspective, if they offer it in a small size, I would go for something that offers sizing. Hope that helps.

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..

With a tape measure. That is obvious. Then you find the sizing chart which is usually on the web page with the hat. dont forget to scroll down because you will see sizing charts for pants shirts shoes etc. You can also wrap a string around your head and mark it with tape or a pen then roll it out and measure it flat with a ruler. If you can't find a sizing chart then go to another web site that has a sizing chart.

The size you need depends on the size of your nose, in particular how wide the bridge of your nose is and the width of your nostrils. You don 't have to measure, just look. If your not sure buy a small pack of laege ones and try them. I also recomend buying the Tan , not the clear. The clear ones don 't stick very well.

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.

not that I can tell. I've been swimming for about 8 years (gone through maybe 10-12 pairs of goggles) and I found that these fit great for my face :-)
