First, find Optical Quality Reading Glasses
your current prescription. I keep mine in the health file in my filing cabinet. If you cannot find your prescription, visit wherever you last longer had your eyes examined and request a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law to release your eyewear prescription to you. You now need to be aware 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 numbers, there is yet another critical amount, the Pupillary Distance, or PD. This is a measure, in millimeters, of the area between your eye. Optical Quality Reading Glasses
Within the example prescription above, you will see the Pupillary Distance of the individual is 62. Write down this number also, it is the seventh of your seven critical figures.
A relatively less critical quantity is your temple span. If you’re lucky, you’ll also see a temple size and bridge size in your prescription. If not, don’t sweating it, you can shape it out yourself. The temple span describes the distance of both bars that connect the eyeglasses to your ears. It really is measured from where in fact the 90-degree curve from your lens structure to the side bars (temples) commences to the end of the temple, like the curve. It is not assessed from the flex point of the temples, because the “stub” between your flex point and lens structure is not really a standard size.

Now, remove some measuring tape (preferably the type of tape used for appropriate clothes and sewing, as it’s very flexible) and measure an existing pair of spectacles that fit comfortably. The average temple period for men is 135mm or 145mm. For women, 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 receive the measurement in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online glasses stores, temple size is shown inside 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 at a site focusing on designer spectacles, where you have the option to source your own temple size.
Frankly, temple size is not really a huge deal. I’ve one couple of glasses with 135mm temples and another with 140mm temples. Both pairs fit pleasantly. If for reasons uknown 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 man and 135mm temples if you are a woman. Chances are, this length will fit perfectly.
