First, find Bifocal Sunglasses Reading Glasses your present prescription. I keep mine in the health file in my own filing cabinet. If you cannot find your prescription, visit wherever you earlier had your sight examined and ask for a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law to release your eyewear prescription to you.

Write down a quick backup of the six figures or simply keep your prescription handy. These six critical numbers define how your lens will be carved. Any online eyewear retailer will require the input of these six numbers.

Now, remove some measuring tape (ideally the sort of tape used for fitted clothes and sewing, as it is very flexible) and measure an existing pair of spectacles that fit perfectly. The average temple span for men is 135mm or 145mm. For women, 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 receive the dimension in millimeters. Temple measures are usually available in 5mm increments, such as 130, 135, 140, 145, etc. At most online eye glasses stores, temple duration is shown in a frame description which is not customizable. Therefore, you 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 type your own temple size.

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 size will fit comfortably.
