Eye glass measurements??
I was wondering, there are three numbers on my glasses. They are 48 19 135

What do these numbers stand for.

I want to by a pair of glasses online because I only need magnifiers because my eyes get strained so much when I read.

I have already been to an eye doctor so I knoe everything I need to know abot what level of glasses I need.

I really need help with this!

Judy B is quite right but it%26#039;s important to add that it only really specifies the fit of that particular frame. It%26#039;s no assurance that, if one with those numbers fits you, any other one with the same numbers will, too.

It%26#039;s quirk of the measurement system, but another frame with the same numbers could be a very different fit on your face.
The numbers, especially the first two, are more for helping with ordering the frame and fitting lenses to it, rather than being the equivalent of a shoe or dress size.
