First, find Polycarbonate Reading Glasses
your current prescription. I keep mine in the health file in my own filing cabinet. If you cannot find your prescription, visit wherever you earlier had your eyes examined and request a duplicate. 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 figures, there is yet another critical number, the Pupillary Distance, or PD. That is a measure, in millimeters, of the space between your sight. Polycarbonate Reading Glasses
Within the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Jot down this quantity also, it is the seventh of your seven critical figures.

A somewhat less critical number is your temple span. If you’re blessed, you’ll also visit a temple size and bridge size in your prescription. If not, don’t sweat it, you can number it out yourself. The temple size describes the length of the two bars that hook up the glasses to your ears. It is measured from where the 90-degree curve from your lens structure aside bars (temples) begins to the end of the temple, including 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 fitting clothes and sewing, as it is very flexible) and evaluate an existing pair of spectacles that fit easily. The average temple size for men is 135mm or 145mm. For girls, 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 find the dimension in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eyeglasses stores, temple length is shown within the frame description and it is not customizable. Therefore, you need to find a frame with a proper temple size. This sometimes varies if you are at a site specializing in designer spectacles, where you have the choice to input your own temple size.

Honestly, temple size is not really a huge deal. I’ve one pair of spectacles 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 allow that stop you from making an eyewear purchase online. Instead, simply choose 140mm temples if you are a man and 135mm temples if you are a female. It’s likely that, this duration will fit perfectly.
