First, find No Line Progressive Bifocal Reading Glasses
your current 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 eyes examined and require a duplicate. 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 pieces 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 the example prescription above, you will see the Pupillary Distance of the patient is 62. Jot down this quantity also, it is the seventh of your seven critical figures.
A slightly less critical quantity is your temple size. If you’re blessed, you’ll also visit a temple size and bridge size in your prescription. If not, don’t perspire it, you can shape it out yourself. The temple size describes the length of both bars that hook up the eyeglasses to your ears. It is measured from where the 90-degree curve from your zoom lens structure aside bars (temples) begins to the end of the temple, like the curve. It isn’t assessed 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 (preferably the kind of tape used for appropriate clothes and sewing, as it is very flexible) and evaluate an existing couple of glasses that fit pleasantly. The average temple span for men is 135mm or 145mm. For women, 130mm to 140mm is standard. When your tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to get the dimension in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eye glasses stores, temple period is shown in just a frame description and is also not customizable. Therefore, you need to find a frame with an appropriate temple size. This sometimes varies if you are in a site specializing in designer spectacles, where you have the choice to input your own temple size.
Seriously, temple size is not a huge deal. I’ve one couple of spectacles with 135mm temples and another with 140mm temples. Both pairs fit comfortably. 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 female. Chances are, this size will fit pleasantly.
