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

What I did was, using a set of metric vernier calipers measure the outside diameter of bothe the Ocular lens (eyepiece) and the objective lens. Then using the Butler creek measurement table, chose the size as close too or slightly smaller than that measurement. I too had issues with finding what I needed and I did have to surf about a bit, but I finally found a table that had all of scope cap sizes and measurements. 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.

check the scope's spec. sheet it should have the diameters of the lenses on it.

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 measured the width of my skull by placing my forehand on a ruler, then putting my head between my hands. It is difficult to take an accurate measurement. I kept getting different numbers. My best guess is my skull is 6 inches wide. The sunglasses fit perfectly. They are snug, but not tight. They are supposed to be snug. If your skull is 0.25 inches wider than mine, I would not recommend the sunglasses.

Your lens should say what distance it is accross the lens (diameter) or you can measure it.

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

No there is not a sizing chart. The glasses are adjustable on the side arms up by the lens, but that is it. Hope this helps.

If you are using a glove at present that should be your glove size. If you aren't using a glove, go to the Bionic Glove website and they will give you directions on how to get your correct size.

The goggles have adjustable straps. They can fit anyone. Unless you have a really large head...or your placing the goggles on a part of your body that doesn't use goggles.

The goggles only come in one size, but they are adjustable. I looked at my boxes of contact lenses (they had the prescription information on the sides) to decide what level of correction I needed for the goggles. The goggles are great; I can see well under the water, which is great when doing laps in the pool. They also arrived very quickly from the company. I highly recommend them.

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.
