First, find 3 Reading Glasses
your present prescription. I keep mine in medical file in my own filing cabinet. If you can’t find your prescription, visit wherever you last had your sight examined and ask for a duplicate. Your optician, optometrist, or ophthalmologist is required by law release a your eyewear prescription for 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 one more critical amount, the Pupillary Distance, or PD. That is a measure, in millimeters, of the area between your eye. 3 Reading Glasses
In 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 quantities.
A relatively less critical number is your temple span. If you’re lucky, you’ll also visit a temple span and bridge size in your prescription. If not, don’t perspire it, you can figure it out yourself. The temple duration describes the space of the two bars that connect the eyeglasses to your ears. It is measured from where the 90-level curve from your lens structure to the side bars (temples) commences to the end of the temple, including the curve. It is not measured from the flex point of the temples, because the “stub” between the flex point and zoom lens structure is not really a standard size.

Now, take out some measuring tape (ideally the kind of tape used for fitted clothes and sewing, as it is very flexible) and measure an existing couple of spectacles that fit pleasantly. The average temple duration for men is 135mm or 145mm. For ladies, 130mm to 140mm is standard. Should your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to find the measurement in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online glasses stores, temple span is shown inside a frame description which is not customizable. Therefore, you need to find a frame with a proper temple size. This occasionally varies if you are in a site focusing on designer glasses, where you have the option to type your own temple size.
Actually, temple size is not a huge deal. I’ve one pair of spectacles with 135mm temples and another with 140mm temples. Both pairs fit easily. 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 man and 135mm temples if you are a female. Chances are, this period will fit comfortably.
