First, find Reading Glass Strength Chart
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 eyes examined and obtain a copy. Your optician, optometrist, or ophthalmologist is necessary 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 numbers, there is one more critical quantity, the Pupillary Distance, or PD. This is a solution, in millimeters, of the area between your sight. Reading Glass Strength Chart
Within the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Jot down this amount also, it is 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 sweating it, you can body it out yourself.

It is measured from where in fact the 90-degree curve from your zoom lens structure to the side bars (temples) starts to the very end of the temple, including the curve.

Now, remove some measuring tape (preferably the kind of tape used for fitted clothes and sewing, as it’s very flexible) and assess an existing pair of eyeglasses that fit easily. The average temple period for men is 135mm or 145mm. For girls, 130mm to 140mm is standard. Should your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to obtain the dimension in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple size is shown within the frame description and is also not customizable. Therefore, you need to discover a frame with an appropriate temple size. This sometimes varies if you are in a site focusing on designer glasses, where you have the choice to type your own temple size.
Frankly, temple size is not a huge deal. I’ve one pair of eyeglasses 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 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 duration will fit comfortably.
