First, find Rx Reading Glasses
your current prescription. I keep mine in medical file in my own filing cabinet. If you cannot find your prescription, visit wherever you last had your sight examined and require a backup. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription for you. You now need to make note 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 amounts, there is yet another critical quantity, the Pupillary Distance, or PD. That is a measure, in millimeters, of the area between your eyes. Rx Reading Glasses
Within the example prescription above, you will see the Pupillary Distance of the patient is 62. Write down this quantity also, it’s the seventh of your seven critical amounts.

A relatively less critical quantity is your temple size. If you’re lucky, you’ll also visit a temple length and bridge size in your prescription. If not, don’t sweating it, you can shape it out yourself. The temple duration describes the space of both bars that connect the eyeglasses to your ears. It really is measured from where the 90-level curve from your lens structure to the side bars (temples) begins to the very end of the temple, like 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, remove some measuring tape (preferably the type of tape used for fitted clothes and sewing, as it is very flexible) and measure an existing couple of glasses that fit comfortably. An average temple span for men is 135mm or 145mm. For ladies, 130mm to 140mm is standard. When your tape only has inches, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to obtain the measurement in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online eye glasses stores, temple size is shown inside a frame description and is also not customizable. Therefore, you need to discover a frame with an appropriate temple size. This occasionally varies if you are at a site specializing in designer glasses, where you have the option to source your own temple size.

Honestly, temple size is not a huge deal. I’ve one couple of glasses 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 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. It’s likely that, this size will fit easily.
