There are many types of frame materials, and the most common one is PC material, which is cheap. Impact resistant. TR material is currently the mainstream non-metallic material in the eyeglass mart, with excellent toughness, weight, and compression resistance. Due to its good elasticity, it is also called "memory plastic".

Because it also belongs to plastic, the paint layer is relatively easy to peel off, and with better workmanship, it can last for about 2-3 years.

Although tungsten titanium has the name of both tungsten and titanium, it is a plastic steel material that is not widely used at present. Although its flexibility is not as good as TR, it is not bad either. The weight is relatively light, the strength is high, and it is not easy to peel off the paint.

Most people choose the full range of glasses on eyeglass mart, which are relatively safe and sturdy, with a fashionable and sporty style. Cleaning and maintenance are also relatively simple, and the thickness of the lens can be appropriately covered.

The browline frame is also divided into an upper-half frame and a lower-half frame. It looks more refined, and due to the absence of half a frame, the field of view is wider, the weight is relatively light, and cleaning is relatively simple.

Frameless glasses have gradually become popular in recent years. This type of glass exudes elegance. The integrated appearance looks very harmonious, and the weight can be greatly reduced with a lighter degree.

But when the degree is high, the edge of the lens will be thicker, which will increase the weight. Therefore, if you have a high degree and want to experience the feeling of being frameless, you can choose lenses with a high refractive index.
