First, find Safety Reading Glasses your current prescription. I keep mine in medical file in my own filing cabinet. If you can’t find your prescription, visit wherever you previously had your eyes examined and demand a backup. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription to you. You now need to make note of a few critical bits 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, take out some measuring tape (preferably the kind of tape used for appropriate clothes and sewing, as it’s very flexible) and assess an existing couple of eyeglasses that fit perfectly. An average temple span for men is 135mm or 145mm. For women, 130mm to 140mm is standard. In case your tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to have the measurement in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eyeglasses stores, temple size is shown in a frame description which is not customizable. Therefore, you need to find a frame with a proper temple size.
Actually, temple size is not really a huge deal. I have one couple of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit easily. If for reasons uknown you can’t come up with a temple measurement, don’t let that stop you from making an eyewear purchase online. Instead, simply choose 140mm temples if you are a man and 135mm temples if you are a female. Chances are, this length will fit comfortably.
