Know the lens and coatings
You also need to decide what lens material and which lens coatings, if any, you want. Are polycarbonate, high-index or regular plastic lenses best for you? Do you need ultraviolet(UV) coating? What about an anti-reflective coating? Is a tint a good idea? Here is an instruction about the lens and coatings noxglass.com provides, and you can choose the lens and/or coatings you need.
Understand your prescription and PD especially
We have prepared an article about how to read the eyeglass prescription, you may need a reading.
And here is another important question of buying eyeglasses online, PD (pupillary distance) measurement.
PD is the distance between the centre of one pupil to the centre of the other pupil. Prescription glasses are made so that the distance between the optical centers of the glasses' lenses, is the same as your PD.
For your convenience, noxglass.com prepared an instruction about how to measure your pd by yourself or by your friend.
And please also keep in mind, PD is a part of your eyeglasses prescription, the optician have the obligation to provide the PD together with other parts of your prescription.
Get the eyeglasses fit for you
The way that eyeglasses fit your face and head is another important issue. Frames that are too large or too small not only is uncomfortable, but you also can get a headache if you're not looking through the optical centers of the lenses.
You should know there are numbers on each eyeglass frame to indicate the size, in 52-18-135 format, the first number 52 means the lend width is 52mm, is the widest length of the place for the lens, and 18mm is the bridge length, it's the part just above your nose, and 135mm is the temple length, or somewhere else calls it arm or leg. So, you must have a pair of eyeglasses which you feel the best fit, remember the numbers on the temple, and when you place order online, you can search for the exact or similar size, to ensure the fit of the glasses frame.
And, another method is to choose the bendable frame, or those frames with spring hinge. Now in the market, there are various kinds of bendable frames, their changing range is much larger than the original plastic or stainless steel frames, such as memory titanium frames, TR90 frames, and jelly frames. You can also choose the glasses frame with spring hinges, spring hinge is a spare part ensuring the frame temple can be fold both inside and outside, and when the face width is larger than the total width of the glasses frame, the spring inside can help face to bear some pressure.
So, above are the concerns of purchasing eyeglasses online, and the solution we recommended. Considering purchasing eyeglasses online often is less expensive and may be more convenient, if you already know which frames you want to purchase and have measurements taken by an optical professional, it can be a delight to sit down at the keyboard to order your new eyeglasses and wait for them to knock the door.
