» The goal of this article is to simply summarize what you need to do to buy your first pair of glasses online. I’ll not recommend particular suppliers, as you will get that info in a number of of my other articles and also browse the links on the right of the page. Purchasing eyewear online seems daunting at first. If you’re like me, purchasing and installing prescription glasses always appeared like a complex technique best left to professionals. 3m Prescription Safety Glasses Frames
The simple truth is, if you know your prescription and have your existing rx glasses very useful, it is actually quite simple to buy glasses online. 3M Safety CX7000 Gold

First, find 3m Prescription Safety Glasses Frames
your present prescription. I keep mine in the health file in my own filing cabinet. If you can’t find your prescription, visit wherever you last had your eye examined and demand a duplicate. Your optician, optometrist, or ophthalmologist is necessary by law to release your eyewear prescription to 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 quantities, there is one more critical quantity, the Pupillary Distance, or PD. That is a measure, in millimeters, of the space between your eyes. 3m Prescription Safety Glasses Frames
In the example prescription above, you’ll see the Pupillary Distance of the patient is 62. Jot down this quantity also, it’s the seventh of your seven critical figures.

A slightly less critical number is your temple size. If you’re lucky, you’ll also visit a temple period and bridge size in your prescription. If not, don’t sweat it, you can figure it out yourself. The temple duration describes the distance of the two bars that connect the eyeglasses to your ears. It is measured from where in fact the 90-degree curve from your zoom lens structure to the side bars (temples) begins to the very end of the temple, including 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 a standard size.

Now, remove some measuring tape (ideally the type of tape used for appropriate clothes and sewing, as it is very flexible) and assess an existing pair of glasses that fit comfortably. The average temple duration for men is 135mm or 145mm. For women, 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 way of measuring in millimeters. Temple measures are generally available in 5mm increments, such as 130, 135, 140, 145, etc. For the most part online spectacles stores, temple size is shown in just a frame description and it is not customizable. Therefore, you need to find a frame with an appropriate temple size. This occasionally varies if you are in a site focusing on designer glasses, where you have the choice to source your own temple size.

Seriously, temple size is not really a huge deal. I’ve one pair of spectacles with 135mm temples and another with 140mm temples. Both pairs fit pleasantly. 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. It’s likely that, this span will fit perfectly.
