your current prescription. I keep mine in medical file in my own filing cabinet. If you can’t find your prescription, visit wherever you lastly had your eye examined and request a duplicate.

Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eye glasses stores, temple period is shown within the frame description which is not customizable.

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