What are the most basic eyeglass lens materials?

It is said that the eyes are the windows to the soul, and the lenses are the life of a pair of glasses. If you have myopia, you cannot do without myopia glasses, but a pair of glasses cannot be without lenses. But what everyone doesn’t know is that there are many types of lenses, not just the epoxy resin lenses we know. So what materials are lenses made of? Which material is better? Let’s find out together.

​

1. What materials are eyeglass lenses made of?

1. Epoxy resin lens.

Epoxy resin lenses are a type of lens that is currently used more frequently. They are made of a compound with a phenolic resin structure. It is light, heat-resistant, impact-resistant and not easy to break. Even if it breaks, it has no corners. It is safe and can effectively block ultraviolet rays. It is loved by many people who wear glasses.

2. Glass lenses.

The image quality of laminated glass lenses is slightly higher than that of epoxy lenses. It is more scratch-resistant and abrasion-resistant than lenses made of other materials. The lenses are thinner, have better electronic optical properties, and are cheaper, but they are heavier and more fragile.

3. PC lens.

The chemical name of PC lens is polypropylene, which is a thermosetting material. PC lens is also called "space lens" and "universe lens". PC lenses are tough, not easy to crack, and resistant to collision, so they are also called safety lenses. They are also the lightest material currently used for eyeglass lenses, but they are relatively expensive. In terms of performance, PC sheets are stronger than epoxy resin sheets.

4.AC lenses.

PC lenses and AC lenses are both epoxy lenses, but their processing technology is different. The difference is that the former is harder and the latter is too soft. AC lenses have excellent toughness, light weight and high perspective. , good anti-fog performance.

5. Polarized lenses.

Generally used in sunglasses, it is an essential equipment for car owners and fishermen. It can filter out a lot of glare and avoid dazzling and dazzling. However, if the curvature of the lens itself cannot be optical In normal refractive conditions, the polarization effect is weakened, the image is effectively affected, and the durability is poor.

6. Nylon lens.

Nylon lenses are made of polyester. Nylon lenses have very high ductility, good optical quality, strong impact resistance, and are generally used as protective equipment.
