Narrow (small faces) = 40-48 lens width
Medium (average) = 49-54mm lend Width

For RX-able Models
 the "optical standard" measurement is given. This number is also inscribed on the inner temples of the glasses. There are three sets of numbers:
1. The first number listed gives the width of each of the lenses.
2. The second is the bridge, which is the distance between the lenses.
3. The third is the length of the temple arms.

You can check your pupillary distance easily by looking in a mirror using the folding method:
