The main advantages of sunglass near meplastic lenses are light, half as heavy as glass lenses, not fragile, and rich in color. When not specially treated, the UV protection function is superior to glass lenses.

Among them, resin sunglass near-melenses have the best optical performance, surface wear resistance, and UV resistance, but their cost is relatively high.

The main drawback of plastic lenses is that their surface wear resistance is not as good as glass lenses, so care should be taken when using and maintaining them. Due to the thin and soft nature of the lenses, there is often some deformation after framing under pressure, which affects the optical properties.

The main advantage of glass lenses is that their optical performance is relatively stable (ground glass) and not affected by framing pressure. The main drawback is that it is easy to damage and heavy.

Among them, Tempered glass lenses are not easy to be damaged after special thermal polymerization treatment. They are also safety lenses like resin lenses. Currently, sunglass near mewith glass lenses is rarely seen.

After adding full-color or half-color resin lenses and glass lenses to the general optical frame, they can also be used as sunglasses and can be adjusted to make myopia sunglasses.

The frames of some mid to high-end sunglasses meet or even exceed the standards of optical frames, and can be used as optical frames.
