How to clean a new contact lens case？

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.
What is an aspheric lens?
Strictly speaking, any lens with a refractive surface that is not a sphere is an aspheric lens, including ordinary astigmatism lens, progressive multi-focal lens, Aspheric apical lens, etc. But customarily, our daily aspheric lens refers to the Aspheric apical lens. From the center of the lens to the periphery, the radius of curvature increases (the surface of the lens flattens out).
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.
Do You Need Long Distance Glasses?
If you are struggling to see things at a distance, you may need a pair of glasses for distance to correct your vision. The symptoms of myopia might include sitting closer to the TV, headaches or eye strain, or rubbing your eyes more than usual. And you can click here to know more symptoms.
If you are over 40 and currently wear glasses for distance vision, you might need to update your lenses at some point to cater for presbyopia, which is an age-related condition whereby your close-up vision can begin to deteriorate.
So, the glasses for distance would be very important for those people who have nearsightedness. If the eye doctor advised you to wear glasses for myopia, you need single vision lenses. This means the lens has one dioptric power throughout, optimized for distance in this case. If you have developed presbyopia, you may need to wear a pair of varifocal glasses to correct your vision.
Gold round frame eyeglasses
Round metal frames have become a hot trend in the last two years, and the pop culture of metal glasses has become unstoppable. A round frame divides a big frame and a small frame, and a small round frame is more delicate. But the requirement for facial features is very high, and the big round frame is more lively and lovely.
But for glasses, in addition, to become fashion accessories, it is very important that they should be commensurate with their temperament, personality. Small round frames are more suitable for small faces and are more delicate, while larger faces will look larger and rounder.
