your current prescription. I keep mine in the health file in my filing cabinet. If you cannot find your prescription, visit wherever you lastly had your sight examined and demand a backup. Your optician, optometrist, or ophthalmologist is necessary by law release a your eyewear prescription to 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 figures, there is yet another critical amount, the Pupillary Distance, or PD. That is a strategy, in millimeters, of the area between your eyes. Reading Glasses Prescription Strength
In the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Write down this quantity also, it’s the seventh of your seven critical figures.

Now, take out some measuring tape (preferably the kind of tape used for fitted clothes and sewing, as it is very flexible) and evaluate an existing couple of eyeglasses that fit comfortably. The average temple duration for men is 135mm or 145mm. For females, 130mm to 140mm is standard. Should your tape only has ins, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to obtain the dimension in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple size is shown in just a frame description and it is not customizable. Therefore, you will need to find a frame with an appropriate temple size. This occasionally varies if you are in a site focusing on designer spectacles, where you have the option to type your own temple size.
Honestly, temple size is not a huge deal. I have one pair 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 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 pleasantly.
