First, find Bi Focal Reading Glasses
your present prescription. I keep mine in medical file in my filing cabinet. If you can’t find your prescription, visit wherever you previously had your sight examined and obtain a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law to release your eyewear prescription to you. You now need to make note 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 yet another critical quantity, the Pupillary Distance, or PD. That is a strategy, in millimeters, of the space between your eye. Bi Focal Reading Glasses
In the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Jot down this amount also, it’s the seventh of your seven critical figures.
A slightly less critical number is your temple duration. If you’re lucky, you’ll also visit a temple period and bridge size in your prescription. If not, don’t perspire it, you can shape it out yourself. The temple span describes the distance of both bars that connect the glasses to your ears. It really is measured from where the 90-degree curve from your zoom lens structure to the side bars (temples) begins to the end of the temple, like the curve. It isn’t measured from the flex point of the temples, because the “stub” between your flex point and lens structure is not a standard size.

Now, take out some measuring tape (ideally the kind of tape used for appropriate clothes and sewing, as it is very flexible) and measure an existing couple of glasses that fit pleasantly. An average temple period for men is 135mm or 145mm. For females, 130mm to 140mm is standard. If the tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the measurement in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online spectacles stores, temple size is shown inside a frame description which is not customizable. Therefore, you need to find a frame with a proper temple size. This sometimes varies if you are at a site specializing in designer eyeglasses, where you have the option to source your own temple size.
Actually, temple size is not a huge deal. I have 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 let 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 woman. Chances are, this duration will fit comfortably.
