your current prescription. I keep mine in medical file in my filing cabinet. If you can’t find your prescription, visit wherever you previously had your eyes examined and ask for a backup. Your optician, optometrist, or ophthalmologist is necessary by law release a your eyewear prescription for you.

Now, remove some measuring tape (preferably the kind of tape used for fitting clothes and sewing, as it’s very flexible) and evaluate an existing couple of glasses that fit pleasantly. The average temple duration for men is 135mm or 145mm. For females, 130mm to 140mm is standard. When your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to obtain the way of measuring in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. At most online glasses stores, temple size is shown within the frame description and is also not customizable. Therefore, you need to discover a frame with an appropriate temple size. This occasionally varies if you are in a site specializing in designer glasses, where you have the choice to input your own temple size.
Genuinely, temple size is not a huge deal. I have one pair of glasses with 135mm temples and another with 140mm temples. Both pairs fit pleasantly. If for some reason you can’t think of a temple measurement, don’t allow that stop you from making an eyewear purchase online. Instead, simply choose 140mm temples if you are a guy and 135mm temples if you are a female. Chances are, this length will fit pleasantly.
