Classification of sunglasses lenses

Classification of sunglasses lenses

There is no big difference in the appearance of the lenses, but the safety of lenses made of different materials is worlds apart.

At present, the four most common lenses on the market are glass lenses, resin lenses, PC lenses, and TAC lenses.

Glass lenses

Although wear-resistant and has good optical performance, the use of the lens is gradually reduced because of the heavy weight of the lens.

Resin lenses

Easy to color, light and impact resistant, becoming one of the mainstream materials for popular sunglasses;

However, the resin lens easily collapses during the edge cutting process, and it will still shatter when it encounters a huge impact force.

TAC lenses

It is one of the polymer materials with better light transmittance.

As a sun lens, TAC has the characteristics of acid and alkali resistance, light and thin texture, and high cost performance.

However, TAC lenses have poor wear resistance and unstable optical properties. Although they are cheap, they are finally abandoned by most famous foreign brands.

PC lens

It is characterized by lightness, good coloring properties, and stronger impact resistance, which is why it is expensive.

But its advantages are also obvious. PC lenses can be said to be a revolutionary upgrade to traditional lenses:

①It overcomes the spherical surface and astigmatism problems caused by the easy deformation of the traditional TAC lens after being framed;

②At the same time, the PC lens adopts polymer material with strong impact resistance.

It is 60 times that of glass lenses, 20 times that of TAC lenses, and 10 times that of resin lenses. It is known as the safest material in the world.

It is widely used in aerospace and military fields.

③ The weight of PC lenses is very light, 37% lighter than the common resin lenses, which can relieve the pressure of the lenses on the bridge of the nose.

④PC lens is not easy to yellow, ordinary resin lens is easy to yellow.

Classification of sun lens materials

1. Plastic lens. Plastic lenses are mainly divided into three types: resin lenses, PC lenses, and acrylic lenses. They have the advantages of being light and unbreakable. Compared with glass lenses, their anti-ultraviolet performance is better; however, plastic lenses have poor wear resistance and are afraid of impact. When recuperating, you need to pay more attention.

2. Glass lens. The optical performance of glass lenses is stable and not easily deformed, but they are fragile and have insufficient safety performance. In view of this situation, the safety performance of the developed strengthened glass lenses will be much higher.

3. Polarized lenses. The polarized lens is mainly a lens produced by the polarization principle of light, which can make the field of view clearer and block the glare outside the lens. It is a lens that is widely used in the market today.

4. Color-changing lenses. A photochromic lens is a lens that can produce different colors according to the change of light. It allows the eyes to adapt to different light environments, and sunglasses with photochromic lenses are also known as the most convenient myopia sunglasses.

What are the lens materials of sunglasses

The lens materials of sunglasses can be divided into three categories: glass lenses, resin lenses, and PC lenses.

Glass lenses are the best optical materials, 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. In addition to ordinary glass lenses, there are also high-end tempered glass polarized lenses, which are anti-explosion and anti-flower, perfect for UV protection and glare protection.

The most commonly used lenses in sunglasses are 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.

PC lenses are excellent in impact resistance and not easy to break, and are suitable for making sports sunglasses. The performance of the PC sheet is better than that of the resin lens, of course, its price is higher.

The above is all about the best material for sunglasses lenses. Thank you for your reading and support!
