Science and Art: What Glasses Are Made Of

Eyewear plays an indispensable role in daily life, providing us with a clear and comfortable visual experience. However, have you ever wondered what glasses are made of? Read this piece and we'll give you a brief guide to what materials are used in the production of eyewear.

What are eyewear frames made of?

The common understanding is that the types of materials used to make frames are simply classified as metal or plastic. However, there are so many different types of metal alloys and plastics to choose from, each with different characteristics and functions, to fit the preferences of different people and styles, and also fit into the many activities of daily life.

 

• Stronger and bold Acetate

Acetate is a strong plastic, durable and often characterized by its bold colors and sturdy make. Acetate frames are usually plated and polished for a smooth finish. It is not the lightest of plastics, due to both its material and sturdy designs; therefore more suitable for lower prescriptions.

• Lightweight and flexible TR90

TR90 is a special thermoplastic memory polymer material. Compared with traditional metal or plastic frames, TR90 material is lighter and has elasticity and memory, the frames can be restored to their original shape after being stressed and are not easy to be deformed or damaged. Due to its lightweight and flexibility, TR90 are often used in children’s frames.

• Hypoallergenic titanium alloy

Being not only the lightest of frame alloys, but Titanium is also anti-allergy and corrosion resistant. Being a rarer metal and ion-plated, a Titanium frame is usually also more expensive than most other alloys. If you are allergic to metals, frames made of pure or beta-titanium would be the safe choice.

 

What are eyewear lenses made of?

Due to its transparency, stability, and lightweight, most lenses nowadays have transformed from the old glass lenses to plastic lenses; usually in resin or PC. Most lenses are then coated to add or enhance different functions. All NextPair lenses are coated with an extra-hard coating, anti-reflective, and anti-radiation, and are 99.4% UV resistant.

 

• Polycarbonate

Polycarbonate is a synthetic resin, the safest of common lens materials. Being impact resistance and lightness, it is especially popular among children or athletes.

• High-Index Resin

High-Index plastics are made of a compound of plastic substrate to achieve a high refractive index, and a thinner lens for the same prescription. Therefore these high-index lenses are especially suitable for people with high myopia or high hyperopia, and also for those who prefer a thinner look and better optical performance.

We hope this article will help you choose between a variety of materials for both frames and lenses. The best time to try a new pair is always now! Explore the most comfortable and innovative eyewear in NextPair.
