First, find Progressive Lens Reading Glasses
your current prescription. I keep mine in the health file in my own filing cabinet. If you can’t find your prescription, visit wherever you lastly had your eye examined and ask for a backup. Your optician, optometrist, or ophthalmologist is required by law release a your eyewear prescription for you. You now need to make note 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.
Furthermore to these six quantities, there is yet another critical amount, the Pupillary Distance, or PD. This is a measure, in millimeters, of the area between your eye. Progressive Lens Reading Glasses
In the example prescription above, you’ll see the Pupillary Distance of the individual is 62. Jot down this number also, it’s the seventh of your seven critical quantities.
A slightly less critical amount is your temple duration. If you’re lucky, you’ll also see a temple span and bridge size in your prescription. If not, don’t sweat it, you can shape it out yourself. The temple span describes the length of both bars that hook up the eyeglasses to your ears. It is measured from where the 90-level curve from your zoom lens structure aside bars (temples) starts to the very end of the temple, including the curve. It isn’t 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, take out some measuring tape (ideally the sort of tape used for fitted clothes and sewing, as it’s very flexible) and assess an existing pair of glasses that fit comfortably. The average temple size for men is 135mm or 145mm. For females, 130mm to 140mm is standard. If the tape only has in ., measure to the nearest eighth or sixteenth and multiply that number by 25.4 to receive the way of measuring in millimeters. Temple lengths are generally available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eye glasses stores, temple size is shown inside a frame description which is 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 eyeglasses, where you have the option to input your own temple size.
Seriously, temple size is not a huge deal. I have one pair of spectacles with 135mm temples and another with 140mm temples. Both pairs fit easily. 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 guy and 135mm temples if you are a female. It’s likely that, this span will fit easily.
