The truth is, if you understand your prescription and have your existing rx glasses useful, it is actually quite simple to acquire glasses online.

First, find Reading Glasses Clip On
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 eyes examined and ask for a copy. Your optician, optometrist, or ophthalmologist is required by law to release 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 number, the Pupillary Distance, or PD. That is a measure, in millimeters, of the space between your sight. Reading Glasses Clip On
In the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Jot down this number also, it is the seventh of your seven critical amounts.
A somewhat less critical quantity is your temple size. If you’re lucky, you’ll also see a temple duration and bridge size in your prescription. If not, don’t perspire it, you can shape it out yourself. The temple period describes the length of the two bars that hook up 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 very end of the temple, like the curve. It is not measured from the flex point of the temples, because the “stub” between your flex point and zoom lens structure is not really a standard size.

Now, remove some measuring tape (preferably the type of tape used for fitting clothes and sewing, as it is very flexible) and evaluate an existing couple of spectacles that fit perfectly. An average temple duration for men is 135mm or 145mm. For ladies, 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 find the measurement in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. At most online spectacles stores, temple duration is shown within a frame description which is not customizable. Therefore, you need to find a frame with an appropriate temple size. This occasionally varies if you are in a site specializing in designer eyeglasses, where you have the choice to type your own temple size.
Truthfully, temple size is not really a huge deal. I have one couple of glasses with 135mm temples and another with 140mm temples. Both pairs fit easily. If for reasons uknown you can’t think of 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 easily.
