How to buy glasses that have quality assurance online?

First of all, you need to find a good eyewear online store and determine if there is any discount information. Big glasses usually have preferential information, and there are certain preferential activities. Lenses are very important to us, so the best quality is good. The price can be considered as the average level because low-level lenses are best not to prevent damage to our eyes. The frame is not that important, and it is only used to support the lens. Choose a pair of good-quality glasses for this combination. Optometry is closely related to the quality of the glasses. If it's not accurate, your glasses must be substandard. If your optometry data is good, you will get a real pair of glasses. You need to make sure your optometric data is accurate, which is a process you must go through when wearing glasses online.


The advantages of contact lenses

Contact lenses are worn directly over the eye. Contact lenses are tightly attached to the surface of the eye and can always follow the eye, so you can maintain the same open field of vision like a normal person. You can participate in sports and outdoor activities without worrying about your glasses falling off or breaking. You can even use colored contact lenses to change the color of your eyes. Some girls, in particular, can make their eyes look bigger and more beautiful with the help of various color contacts.



If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.

However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.

In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.

Design principle of progressive multifocal lens

For the same piece of the lens, the top is used to see far, the bottom is used to see close. The upper and lower degrees are different.

There is not a sudden change in the distance degree fixed above the lens to the near degree fixed below the lens, but a gradual transition between the two through gradual changes in refractive power, which has special benefits over common bifocals or trifocal lenses.

There are three processes for resin-changing lenses.

The incorporation method, known as bulk polymerization, is similar to the method of glass lens, that is, one or more photochromic dyes are directly incorporated into the polymer monomer of the substrate for bulk polymerization, and the lens formed after curing will change color. Discoloration dye is completely integrated into the resin lens substrate, so the lens made of color persistence is very good.

The uniformity of discoloration and the depth of color after discoloration are highly related to the thickness of the lens. Because the thickness of the lenses at all levels is different, there will be a color difference between the depth of discoloration and the uniformity, and the uneven phenomenon of high brightness is more obvious.

The film type is known as the coating method. It is the chromatic resin lens by coating or dipping in a layer of chromatic dye on the base of the resin lens. Because the coating covers the surface of the lens, the color uniformity is good. The coating, which is only about 0.05mm thick, does not provide enough molecules to make the lens dark enough, so the color is relatively less dark, and the discoloration lasts slightly longer.

Infiltration, known as the penetration method, is to use the principle of penetration, through the thermal diffusion method to make the color dye permeate the surface of the resin lens sheet material, with diffusion depth up to 0.15~0.20mm. The lens has a constant color change characteristic. There will be no inconsistency between the center and the surrounding color as the luminosity gets darker. The color-changing resin lens made by infiltration type has the benefits of uniform color-changing, small color difference, fast and thorough color-fading, which is the mainstream of color-changing technology at present.
