First, find Reading Glasses 2.50
your current prescription. I keep mine in the health file in my own filing cabinet. If you can’t find your prescription, visit wherever you previously had your eyes examined and obtain a copy. Your optician, optometrist, or ophthalmologist is necessary by law release a your eyewear prescription for you. You now need to be aware 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.
In addition to these six numbers, there is one more critical number, the Pupillary Distance, or PD. This is a measure, in millimeters, of the space between your eye. Reading Glasses 2.50
In the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Jot down this amount also, it is the seventh of your seven critical numbers.
A relatively less critical number is your temple size. If you’re lucky, you’ll also visit a temple span and bridge size in your prescription. If not, don’t sweating it, you can determine it out yourself. The temple span describes the length of both bars that hook up the eyeglasses to your ears. It is measured from where the 90-degree curve from your zoom lens structure aside bars (temples) commences 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 the flex point and lens structure is not a standard size.

Now, take out some measuring tape (preferably the type of tape used for fitted clothes and sewing, as it is very flexible) and assess an existing couple of spectacles that fit comfortably. An average temple period for men is 135mm or 145mm. For ladies, 130mm to 140mm is standard. In case your tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to find the dimension in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eye glasses stores, temple duration is shown in just a frame description and is also not customizable. Therefore, you need to find a frame with an appropriate temple size. This sometimes varies if you are at a site focusing on designer eyeglasses, where you have the option to input your own temple size.
Honestly, temple size is not really 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 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 woman. Chances are, this span will fit comfortably.
