First, find Glass Analysis Reading
your present prescription. I keep mine in medical file in my own filing cabinet. If you can’t find your prescription, visit wherever you latest had your eyes examined and ask a copy. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription to you. You now need to make note 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.
Furthermore to these six volumes, there is one more critical number, the Pupillary Distance, or PD. This is a solution, in millimeters, of the area between your eyes. Glass Analysis Reading
Inside the example prescription above, you will see the Pupillary Distance of the patient is 62. Write down this amount also, it’s the seventh of your seven critical volumes.
A somewhat less critical amount is your temple duration. 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 body it out yourself. The temple duration describes the space of the two bars that hook up the eyeglasses to your ears. It is measured from where the 90-level curve from your lens structure to the side 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 your flex point and lens structure is not really a standard size.

Now, remove some measuring tape (ideally the sort of tape used for fitted clothes and sewing, as it’s very flexible) and evaluate an existing couple of spectacles that fit easily. The average temple size for men is 135mm or 145mm. For women, 130mm to 140mm is standard. When your tape only has ins, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to find the dimension in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eyeglasses stores, temple length is shown within a frame description which is not customizable. Therefore, you will need to discover a frame with a proper temple size. This occasionally varies if you are at a site focusing on designer spectacles, where you have the option to type your own temple size.
Truthfully, temple size is not a huge deal. I’ve one couple of glasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably. 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 guy and 135mm temples if you are a female. Chances are, this span will fit comfortably.
