First, find Reading Glasses For Computers
your current prescription. I keep mine in the health file in my filing cabinet. If you cannot find your prescription, visit wherever you previously had your eye examined and request a backup. Your optician, optometrist, or ophthalmologist is necessary by law to release 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 amount, the Pupillary Distance, or PD. That is a measure, in millimeters, of the area between your eye. Reading Glasses For Computers
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 number is your temple size. If you’re lucky, you’ll also see a temple span and bridge size in your prescription. If not, don’t sweat it, you can amount it out yourself. The temple period describes the length of the two bars that connect the eyeglasses to your ears. It is measured from where in fact the 90-level curve from your zoom lens structure to the side bars (temples) starts 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 a standard size.

Now, take out some measuring tape (ideally the type of tape used for appropriate clothes and sewing, as it’s very flexible) and measure an existing pair of glasses that fit comfortably. An average temple span for men is 135mm or 145mm. For women, 130mm to 140mm is standard. When your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive 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 span is shown in just a frame description and is also not customizable. Therefore, you will need to discover a frame with an appropriate temple size. This sometimes varies if you are in a site specializing in designer spectacles, where you have the choice to type your own temple size.
Frankly, temple size is not really a huge deal. I’ve one pair of eyeglasses 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 guy and 135mm temples if you are a female. It’s likely that, this span will fit pleasantly.
