First, find Ultra Lightweight Reading Glasses
your current prescription. I keep mine in medical file in my own filing cabinet. If you can’t find your prescription, visit wherever you last had your eyes examined and ask for a duplicate. Your optician, optometrist, or ophthalmologist is required 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.
Furthermore to these six numbers, there is yet another critical quantity, the Pupillary Distance, or PD. That is a solution, in millimeters, of the area between your sight. Ultra Lightweight Reading Glasses
In 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 numbers.
A somewhat less critical number is your temple duration. If you’re blessed, you’ll also see a temple length and bridge size in your prescription. If not, don’t sweat it, you can determine 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 in fact the 90-level curve from your lens structure aside bars (temples) begins to the end of the temple, including the curve. It is not 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, take out some measuring tape (preferably the type of tape used for appropriate clothes and sewing, as it is very flexible) and assess an existing couple of spectacles that fit perfectly. An average temple period for men is 135mm or 145mm. For women, 130mm to 140mm is standard. If your tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to obtain the dimension in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple size is shown in a frame description and it is not customizable. Therefore, you will need to find a frame with an appropriate temple size. This sometimes varies if you are at a site focusing on designer glasses, where you have the choice to source your own temple size.
Frankly, temple size is not a huge deal. I have one couple of glasses with 135mm temples and another with 140mm temples. Both pairs fit perfectly. 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 female. It’s likely that, this length will fit pleasantly.
