What material is better for the lenses of sunglasses?

Sunglasses, like glasses, are mainly composed of two parts. The difference is the material of the frame and the material of the lens. As far as the frame is concerned, there is no particular difference. The difference between the two lies in the material of the lens. What are the materials of sunglasses lenses, and what materials are better?

Generally speaking, the lens materials of sunglasses can be divided into three categories - glass lens materials, resin lens materials, and PC lens materials.

Glass lens material is the best optical material, but because ordinary glass lenses are relatively easy to break, for those who like outdoor sports, the safety performance is not high, so they are basically not used in sunglasses.

Nowadays, the most common lens material for sunglasses is resin lenses. Resin is a chemical substance with a phenolic structure, which is characterized by light weight, high temperature resistance, impact resistance, and can effectively block ultraviolet rays. It should be said that this is a relatively excellent sunglasses lens material, and the polarized lenses made of this material will make us see things more clearly.

There is also a sunglass lens called the PC sheet on the market. This lens has excellent impact resistance and is not easy to break. It is a material suitable for the manufacture of sports sunglass lenses. It should be said that the performance of the PC sheet is better than that of the resin lens, of course, its price is higher.

Brown lenses can filter out a small amount of blue light, improve visual contrast and clarity, and are better worn in conditions of severe air pollution or a lot of fog. Generally, it can block the reflected light of the smooth and bright surface, and the wearer can still see the fine parts clearly, which is the ideal choice for the driver.

Grey lens material

Grey lens sunglasses filter nearly equal amounts of sunlight and filter out 98% of both infrared and ultraviolet rays. Wearing sunglasses with gray lenses, the original color of the scene will not be changed by the lenses, and it can greatly limit the blocking of strong light. When you are outdoors in summer, wear gray lens sunglasses, which not only pulls the wind and blocks light, but also sees the beauty of the primary color.
