Size guide

Frames come in a variety of sizes to suit a variety of face shapes. Eyeglass size measurements are primarily expressed as a series of 3 numbers.

1. Caliper - Measurement of the horizontal diameter of the lens at its widest point (usually between 48 and 58)

2. Bridge - Distance between the lenses (usually between 15 and 25). The higher the number, the greater the distance.

3. Temple - Temple length (usually between 135 and 150). If you've tried on glasses and noticed that the temples don't sit well, you should look for glasses with a temple length of at least 145 mm.
