your current prescription. I keep mine in the health file in my filing cabinet. If you can’t find your prescription, visit wherever you last had your sight examined and demand a copy. 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). Among other information, you should see three columns on your prescription–sphere, cylinder, and axis.
In addition to these six amounts, there is one more critical amount, the Pupillary Distance, or PD. This is a strategy, in millimeters, of the space between your sight. High Power Magnifying Glass For Reading

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 ladies, 130mm to 140mm is standard. If the tape only has in ., measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the measurement in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple size is shown within a frame description and is not customizable. Therefore, you will need to find a frame with a proper temple size. This sometimes varies if you are in a site specializing in designer glasses, where you have the choice to source your own temple size.
Frankly, 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 easily. 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 woman. It’s likely that, this size will fit easily.
