First, find Reading Glasses Less Than 1.0
your current prescription. I keep mine in medical file in my filing cabinet. If you can’t find your prescription, visit wherever you previously had your eyes examined and request a backup. 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 statistics, there is one more critical quantity, the Pupillary Distance, or PD. This is a measure, in millimeters, of the space between your eyes. Reading Glasses Less Than 1.0
In the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Write down this number also, it’s the seventh of your seven critical quantities.
A somewhat less critical number is your temple duration. If you’re blessed, you’ll also visit a temple length and bridge size in your prescription. If not, don’t sweating it, you can shape it out yourself. The temple span describes the space of the two bars that hook up the spectacles to your ears. It is measured from where in fact the 90-level curve from your zoom lens structure aside bars (temples) begins to the very 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 zoom lens structure is not really a standard size.

Now, take out some measuring tape (ideally the kind of tape used for fitting clothes and sewing, as it is very flexible) and measure an existing couple of eyeglasses that fit comfortably. The average temple span for men is 135mm or 145mm. For females, 130mm to 140mm is standard. In case your tape only has ins, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to get the measurement in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple length is shown in just a frame description and is also not customizable. Therefore, you will need to discover a frame with a proper temple size. This sometimes varies if you are in a site focusing on designer spectacles, where you have the choice to type your own temple size.
Frankly, temple size is not really a huge deal. I’ve one couple of glasses 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 guy and 135mm temples if you are a woman. Chances are, this size will fit perfectly.
