When you buy glasses online, the right size of your eyeglasses is especially important . Because you can not get a chance to try on the frames in a online store, but if you want to make sure the eyeglasses will fit for comfort and looks, should know the best size for your face. In the local spectacle store, you can look at the measurement information which is printed on the inside of one of the temples or on the bridge. And you don’t have to try on too many eyeglasses before you have known your size.
The size information is typically formed a set of three numbers which can be measurement with millimeters. For example, frames those are size 53-18-140. The first number 53 is the horizontal width of frames. The second number 18 is the distance between lenses which are also called the bridge length, and the third number 140 is the length of the temples. Another smaller frame like 50-17-138.
