First, find Reading Glasses Online Test
your current prescription. I keep mine in medical file in my own filing cabinet. If you cannot find your prescription, visit wherever you latest had your eye examined and ask for a copy. Your optician, optometrist, or ophthalmologist is required by law release a your eyewear prescription for 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 volumes, there is yet another critical number, the Pupillary Distance, or PD. That is a measure, in millimeters, of the space between your sight. Reading Glasses Online Test
In the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Jot down this quantity also, it is the seventh of your seven critical amounts.
A slightly less critical amount is your temple period. If you’re blessed, you’ll also visit a temple length and bridge size in your prescription. If not, don’t sweat it, you can number it out yourself. The temple size describes the distance of the two bars that hook up the eyeglasses to your ears. It is measured from where in fact the 90-degree curve from your zoom lens structure aside bars (temples) commences to the very end of the temple, including the curve. It isn’t assessed from the flex point of the temples, because the “stub” between the flex point and zoom lens structure is not a standard size.

Now, take out some measuring tape (ideally the kind of tape used for appropriate clothes and sewing, as it’s very flexible) and measure an existing couple of eyeglasses that fit comfortably. An average temple period for men is 135mm or 145mm. For women, 130mm to 140mm is standard. If the tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to have the measurement in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online glasses stores, temple span is shown in a frame description and it is not customizable. Therefore, you need to discover a frame with a proper temple size. This sometimes varies if you are at a site focusing on designer spectacles, where you have the choice to input your own temple size.
Frankly, temple size is not really a huge deal. I’ve one couple of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit pleasantly. 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 female. It’s likely that, this length will fit perfectly.
