- Temple Length: This is the length of the arms of the glasses, from the hinge to the end that rests behind your ears. Proper temple length ensures the glasses stay in place and do not slide down.

Measuring your PD can seem tricky, but it’s straightforward with the right approach. Here’s a step-by-step method to get an accurate PD measurement:
