your present prescription. I keep mine in the health file in my own filing cabinet. If you can’t find your prescription, visit wherever you latest had your sight examined and demand a backup. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription for you. You now need to be aware of a few critical pieces of information from your prescription (see example above–click to enlarge). Among other information, you should see three columns on your prescription–sphere, cylinder, and axis.

Now, remove some measuring tape (preferably the kind of tape used for appropriate clothes and sewing, as it’s very flexible) and measure an existing pair of spectacles that fit pleasantly. An average temple length for men is 135mm or 145mm. For ladies, 130mm to 140mm is standard. In case your tape only has in ., measure to the nearest eighth or sixteenth and multiply that number by 25.4 to have the way of measuring in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eyeglasses stores, temple length is shown in a frame description and is not customizable. Therefore, you need to discover a frame with an appropriate temple size. This sometimes varies if you are at a site specializing in designer eyeglasses, where you have the option to input your own temple size.
Honestly, temple size is not really a huge deal. I have one pair of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably.

Instead, simply choose 140mm temples if you are a man and 135mm temples if you are a female. It’s likely that, this size will fit perfectly.
