Frame Size Numbers Explained

Reading the numbers

Common markings look like 52□18 with a temple length such as 140. The first number is horizontal lens/eye size; the bridge follows; temple length is separate. Units are millimeters.

Why optics care about size

Progressives need appropriate fitting height. Strong prescriptions interact with eye size for thickness. PD must be realizable inside the chosen frame without extreme decentration.
