How to Choose Reading Glasses?
Find the right power. When choosing reading glasses, finding the right power would be the most important thing. All reading glasses will have signs or stickers indicating their power. In most cases, they will range from +1 to +4 diopter, in increments of +0.25. So, when choosing reading glasses, try the lowest power first.
Test-drive the glasses. If you have brought reading material with you, try reading it at a comfortable length. If you hold the material too far out to be able to read it, you should increase the power. Keep testing the differences powers until can read clearly at the distance that’s more comfortable for you.

Anti-reflection Coating
Anti-reflection Coating, known as reflective coating and antireflection film, is called anti-reflection coating in English, or AR Coating for short. Initially, anti-reflection coating technology was used in the sights of weapons. It was only after the war that the technique was used to improve the performance of eyeglasses. Another problem occurs when taking pictures because the lens's surface is relatively reflective. The resulting photos don't show the eyes of friends who wear glasses. This problem is solved by plating anti-reflection film.

The Pros of Transitions Lenses
First, we will show you the advantages of the transition lenses.
Transition lenses or photochromic glasses are quite cost-effective. With the transition lenses, you don’t have to buy two pairs of glasses: prescription glasses or normal glasses and you do not need to switch them frequently. So, they are also convenient and bring you great convenience.
Carrying two pairs of glasses means that you are much more likely to lose or misplace either of them. Having only one pair of glasses can limit the risk of losing glasses.

Refractive index of spectacle lens
It is generally believed that the higher the refractive index, the better the spectacle lens. Such spectacle lenses are relatively thin, and of course, the price is a bit expensive. When the refractive index increases, the direction of the light entering the lens will change greatly, the focus will move to the lens, the focal length will be smaller, and the diopter will become larger. In order to keep the diopter unchanged, it is necessary to reduce the curvature of the lens, that is, to reduce the curvature of the mirror surface, so that the thickness of the lens can be reduced. This is why the larger the refractive index, the thinner the lens is. Under the same premise of other things, the larger the refractive index, the thinner the lens, the lighter and more beautiful the lens, and the higher the price, but the larger the refractive index is not the better.
