First, find Safety Glasses Chemistry your current prescription. I keep mine in the health file in my filing cabinet. If you can’t find your prescription, visit wherever you last longer had your eyes examined and demand a copy. 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.

Safety Glasses Chemistry Popularly » In the example above, these are abbreviated SPH. CYL. and AXIS. These three columns will have two rows, Right and Kept. Within the prescription above, this is simply abbreviated R and L. Many doctors instead use the latin abbreviations, that happen to be OD and OS. OD means right eyeball and OS means kept eye. Write down a quick backup of the six quantities or simply keep the prescription handy. These six critical quantities define how your lens will be carved. Any online eyewear retailer will require the input of these six numbers.

A slightly less critical number is your temple length. If you’re blessed, you’ll also visit a temple period and bridge size in your prescription. If not, don’t sweat it, you can number it out yourself. The temple duration describes the space of both bars that hook up the spectacles to your ears.

Now, take out some measuring tape (preferably the kind of tape used for appropriate clothes and sewing, as it’s very flexible) and measure an existing pair of spectacles that fit pleasantly. An average temple period for men is 135mm or 145mm. For females, 130mm to 140mm is standard. When your tape only has inches wide, measure to the nearest eighth or sixteenth and multiply that number by 25.4 to find the dimension in millimeters. Temple lengths are usually available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eye glasses stores, temple duration is shown within a frame description and is not customizable. Therefore, you will 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 type your own temple size.

Actually, temple size is not a huge deal. I have one pair of eyeglasses with 135mm temples and another with 140mm temples. Both pairs fit comfortably. If for some reason you can’t think of a temple measurement, don’t allow 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 woman. Chances are, this duration will fit perfectly.
