your current prescription. I keep mine in the health file in my filing cabinet. If you can’t find your prescription, visit wherever you lastly had your eyes examined and obtain a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law release a your eyewear prescription to you. You now need to be aware of a few critical bits of information from your prescription (see example above–click to enlarge).

Now, remove some measuring tape (preferably the sort of tape used for appropriate clothes and sewing, as it is very flexible) and assess an existing couple of spectacles that fit comfortably. An average temple span for men is 135mm or 145mm. For girls, 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 find the measurement in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online glasses stores, temple duration is shown within a frame description and it is not customizable. Therefore, you need to find a frame with an appropriate temple size. This occasionally varies if you are in a site focusing on designer eyeglasses, where you have the option to source your own temple size.
Genuinely, temple size is not really a huge deal. I’ve one pair of glasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably. If for some reason 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 guy and 135mm temples if you are a woman. It’s likely that, this length will fit easily.
