First, find Reading Glasses With Contacts
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 require a duplicate. Your optician, optometrist, or ophthalmologist is required by law to release your eyewear prescription to 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 figures, there is yet another critical number, the Pupillary Distance, or PD. That is a measure, in millimeters, of the area between your eye. Reading Glasses With Contacts
In the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Write down this amount also, it is the seventh of your seven critical quantities.
A slightly less critical amount is your temple length. If you’re lucky, you’ll also visit a temple duration and bridge size in your prescription. If not, don’t sweating it, you can figure it out yourself. The temple span describes the length of both bars that connect the eyeglasses to your ears. It is measured from where the 90-level curve from your zoom 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 the flex point and lens structure is not a standard size.

Now, take out some measuring tape (ideally the sort of tape used for appropriate clothes and sewing, as it is very flexible) and measure an existing pair of spectacles that fit perfectly. An average temple size for men is 135mm or 145mm. For females, 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 receive the dimension in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online glasses stores, temple period is shown inside a frame description and is not customizable. Therefore, you will need to discover a frame with a proper temple size. This sometimes varies if you are at a site focusing on designer eyeglasses, where you have the choice to source your own temple size.
Genuinely, 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 woman. Chances are, this span will fit comfortably.
