What is the material of presbyopic glasses frame

Metal materials: The metal materials used for spectacle frames are divided into three categories: copper alloys, nickel alloys and precious metals. It is required to have certain hardness, softness, elasticity, abrasion resistance, corrosion resistance, light weight, luster and good color and so on. Therefore, the metal materials used to make spectacle frames are almost all alloys or used after metal surface processing.

Natural materials: The natural materials used to make spectacle frames include tortoiseshell, special wood, and animal head horns. Generally, wooden spectacle frames and horn frames are rare, and tortoiseshell spectacle frames are common.

Mixed materials: The mixed frame is exquisite and beautiful in shape, giving people a sense of elegance. Because the outer plastic is in close contact with the inner metal material, it is not easy to burn, which increases the strength of the frame.

What kind of frame is good for reading glasses

Under normal circumstances, the material of reading glasses should be made of metal, because only spectacle frames of this material are better than those of ordinary materials, and have stronger corrosion resistance and stronger impact resistance. Generally, the frame material cannot be selected from substances that are allergic to the skin, otherwise it will feel very uncomfortable when worn on the body, especially the reading glasses are designed for the elderly, and the body of the elderly is relatively young. It is relatively fragile, so when choosing a material, you should choose a material that is not allergic to the skin, otherwise the consequences will be unimaginable.

How to choose the lenses of reading glasses

It is best to use resin for the lenses of reading glasses. This material can effectively resist ultraviolet, infrared, and other things. When wearing it, it will also have a certain degree of fatigue resistance to your eyes, otherwise it will be used. After a while, there will be a certain sense of fatigue, and even if the quality is not good, other diseases may occur. In the end, there is no way to cure it. Therefore, the resin lens is much better than ordinary lenses. The refractive index of this lens It is also quite high. Glasses experts recommend that the elderly should use high magnification reading glasses, varifocal reading glasses, photochromic reading glasses and other bifocal reading glasses clear on top.
