your present prescription. I keep mine in medical file in my filing cabinet. If you can’t find your prescription, visit wherever you last longer had your eye examined and request a backup.

Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online spectacles stores, temple duration is shown within a frame description and is also not customizable. Therefore, you will need to discover a frame with a proper temple size. This occasionally varies if you are at a site specializing in designer spectacles, where you have the choice to type your own temple size.
Seriously, temple size is not really a huge deal. I’ve one pair of spectacles with 135mm temples and another with 140mm temples. Both pairs fit comfortably.

Instead, simply choose 140mm temples if you are a guy and 135mm temples if you are a female. Chances are, this size will fit perfectly.
