First, find Glass Lens Reading Glasses
your current prescription. I keep mine in medical file in my filing cabinet. If you cannot find your prescription, visit wherever you last had your sight 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 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.
In addition to these six figures, there is yet another critical number, the Pupillary Distance, or PD. This is a measure, in millimeters, of the area between your eyes. Glass Lens Reading Glasses
Inside the example prescription above, you will see the Pupillary Distance of the patient is 62. Jot down this amount also, it’s the seventh of your seven critical figures.
A slightly less critical number is your temple span. If you’re lucky, you’ll also see a temple duration and bridge size in your prescription. If not, don’t perspire it, you can number it out yourself. The temple span describes the length 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 very end of the temple, including the curve. It isn’t measured from the flex point of the temples, because the “stub” between the flex point and lens structure is not a standard size.

Now, remove some measuring tape (ideally the kind of tape used for fitting clothes and sewing, as it’s very flexible) and assess an existing pair of eyeglasses that fit easily. An average temple duration for men is 135mm or 145mm. For girls, 130mm to 140mm is standard. If the tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the dimension in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online glasses stores, temple length is shown within the frame description and is also not customizable. Therefore, you need to discover a frame with an appropriate temple size. This occasionally varies if you are in a site focusing on designer glasses, where you have the option to source your own temple size.
Actually, temple size is not really a huge deal. I have one pair of spectacles with 135mm temples and another with 140mm temples. Both pairs fit easily. If for some reason you can’t think of 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 woman. Chances are, this period will fit comfortably.
