First, find 1.0 Reading Glasses
your present prescription. I keep mine in the health file in my filing cabinet. If you cannot find your prescription, visit wherever you last 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 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.
Furthermore to these six amounts, there is yet another critical quantity, the Pupillary Distance, or PD. That is a solution, in millimeters, of the space between your eyes. 1.0 Reading Glasses
In the example prescription above, you will see the Pupillary Distance of the individual is 62. Jot down this amount also, it’s the seventh of your seven critical amounts.
A somewhat less critical amount is your temple length. If you’re lucky, you’ll also see a temple length and bridge size in your prescription. If not, don’t perspire it, you can figure it out yourself. The temple length describes the distance of both bars that hook up the spectacles to your ears. It is measured from where the 90-level curve from your lens structure to the side bars (temples) starts to the very end of the temple, like the curve. It is not measured from the flex point of the temples, because the “stub” between your flex point and zoom lens structure is not a standard size.

Now, take out some measuring tape (preferably the type of tape used for appropriate clothes and sewing, as it’s very flexible) and assess an existing pair of eyeglasses that fit easily. An average temple length for men is 135mm or 145mm. For girls, 130mm to 140mm is standard. If your tape only has in ., measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the way of measuring in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eye glasses stores, temple duration is shown in a frame description and is not customizable. Therefore, you will need to discover a frame with an appropriate temple size. This sometimes varies if you are at a site focusing on designer eyeglasses, where you have the choice to source your own temple size.
Frankly, 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 perfectly. If for some reason you can’t think of 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. Chances are, this size will fit perfectly.
