TAC lenses and resin lenses

The sun is shining outside, so don’t forget to use sunscreen when you go out in spring. Sunscreen is only exclusive to summer. It starts from spring. Alibaba Glasses Wholesale.com has compiled a classification of sunglasses and their characteristics for you. Helpful when shopping for sunglasses.

Anti-reflective protective lens, this kind of lens is coated with a thin layer of magnesium fluoride on the surface to prevent strong light reflection, so that you can see things more clearly without interference from strong light.

Colored lenses, called "dyed lenses", are the addition of some chemical substances during the lens manufacturing process to make the lenses appear colored to absorb light of specific wavelengths.

Tinted lenses, which have the same effect as colored lenses, but are made in a different way by applying color to the surface of the lens.

Polarized lenses, in order to filter the glare of the sun in the same direction on the water, land or snow, add a special coating vertically upward to the lenses, which are called polarized lenses.

Photochromic lenses, also known as "photosensitive lenses." Because silver halide chemicals are added to the lens, the originally transparent and colorless lens will become a colored lens for protection when exposed to strong light.

Glass lens has excellent optical performance and is also the best optical material. However, ordinary glass lenses are easy to break, have relatively weak impact resistance, and are not very safe.

Resin lenses have the characteristics of high temperature resistance. The most notable feature of resin lenses is that they are light in weight, strong in impact resistance, high in safety but easy to wear and scratch.

The impact resistance and crack resistance of PC lenses are stronger than those of resin lenses. The weight is particularly light, and the coloring is also good. The disadvantage is that the wear resistance is poor and the optical system is unstable.

TAC material lens, TAC is processed by solvent casting film, which has acid and alkali resistance and light and thin texture with high cost performance, but its wear resistance is extremely poor and its optical properties are not stable.

Nylon lenses have good elasticity, good optical performance, and strong impact resistance, and are mainly used for goggles. But the wear resistance is poor, and the production cost is relatively high.

Light-colored sunglasses are actually a fashion variant of sun visors. Although their blocking effect on sunlight is smaller than that of sun visors, their fundamental purpose is to play a decorative role.

The sun visor is used to block the sun. In summer, you should use the sun visor to protect your eyes and reduce the fatigue caused by the self-regulation of the eyes and the damage caused by strong light stimulation.

Special sunglasses are an enhanced version of ordinary sunshade glasses. Its indicators are higher than ordinary sunglasses, and it has a greater function of blocking strong light. Generally, it has different requirements for special occasions. It is often used for beaches, skiing, mountain climbing and Outdoor sports such as golf where the sun is strong and require a good view.

Brown sunglasses are recognized as the best lens color, which can absorb almost 100% of ultraviolet and infrared rays; and the soft tone makes the vision comfortable and makes the eyes not easy to fatigue.

Gray series, can completely absorb infrared rays and most of ultraviolet rays, and will not change the original color of the scene. Mild and natural colors are quite popular lens choices.

The green system can absorb all infrared rays and 99% of ultraviolet rays, and the cyan and red in the light can also be blocked, but sometimes the color of the scene will be changed after passing through the green lens.

Yellow lenses can absorb almost 100% of ultraviolet rays and most of the blue light. After absorbing the blue light, the scene you see will be clearer.

The red sunglasses lenses are better at blocking light with shorter wavelengths, while other protection effects are lower than the other three colors.
