First, find Reading Glasses 3.0
your present prescription. I keep mine in the health file in my own filing cabinet. If you can’t find your prescription, visit wherever you earlier had your eye examined and ask for a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law to release 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 volumes, there is one more critical amount, the Pupillary Distance, or PD. This is a measure, in millimeters, of the area between your eyes. Reading Glasses 3.0
Inside the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Write down this amount also, it is the seventh of your seven critical amounts.
A somewhat less critical number is your temple period. If you’re lucky, you’ll also visit a temple length and bridge size in your prescription. If not, don’t sweat it, you can figure it out yourself. The temple duration describes the distance of both bars that connect the eyeglasses to your ears. It is measured from where the 90-degree curve from your lens structure aside bars (temples) starts to the end of the temple, like the curve. It is not assessed from the flex point of the temples, because the “stub” between the flex point and zoom lens structure is not a standard size.

Now, remove 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 glasses that fit perfectly. The average temple span for men is 135mm or 145mm. For women, 130mm to 140mm is standard. If your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to have the measurement in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online spectacles stores, temple size is shown within the frame description and is not customizable. Therefore, you will need to discover a frame with a proper temple size. This occasionally varies if you are in a site specializing in designer spectacles, where you have the option to source your own temple size.
Frankly, temple size is not a huge deal. I’ve one couple of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit easily. 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 man and 135mm temples if you are a female. Chances are, this size will fit easily.
