First, find Half Lense Reading Glasses
your present prescription. I keep mine in medical file in my own filing cabinet. If you cannot find your prescription, visit wherever you earlier had your sight examined and obtain a copy. 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 quantities, there is one more critical amount, the Pupillary Distance, or PD. That is a solution, in millimeters, of the area between your eyes. Half Lense Reading Glasses
Within the example prescription above, you will see the Pupillary Distance of the patient is 62. Write down this amount also, it is the seventh of your seven critical statistics.
A somewhat less critical number is your temple duration. If you’re lucky, you’ll also visit a temple duration and bridge size in your prescription. If not, don’t perspire it, you can body it out yourself. The temple duration describes the length of both bars that connect the glasses to your ears. It is measured from where the 90-degree curve from your lens structure to the side bars (temples) begins to the very end of the temple, like the curve. It is not assessed 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 (ideally the type of tape used for fitting clothes and sewing, as it is very flexible) and assess an existing couple of glasses that fit easily. An average temple duration for men is 135mm or 145mm. For females, 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 measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eyeglasses stores, temple span is shown inside a frame description and is not customizable. Therefore, you will need to find a frame with a proper temple size. This occasionally varies if you are at a site specializing in designer eyeglasses, where you have the choice to source your own temple size.
Actually, temple size is not really a huge deal. I have one couple of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably. If for reasons uknown 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 guy and 135mm temples if you are a female. It’s likely that, this size will fit perfectly.
