Glasses size? are these authentic?

Question

I'm not familiar because i dont wear glasses but what does it mean when the glasses have a size on it because i tried buying frames online and they have different sizes. Here they are:http://www.amazon.com/Authentic-D-G-GABBANA-Eyeglasses/dp/B0016HVJ0G/ref=pd_sbs_a_4

do you think they are authentic?

Answer 1

Yeah they're nice!

Answer 2

All frames have the size written on them.

Most frames now only come in one specific size, but some frames still come in 2 or 3 sizes for different size heads.

That one is a 52-16...which means it will be 120 millimeters wide in total...so if you have a tiny face, they may be wide on you....

If you have someones glasses to measure the total width of first, it will give you a better idea how wide they will be.
