What are the materials of sunglasses lenses? With the continuous popularity of sunglasses, more and more people are wearing them. The materials of sunglasses can be roughly divided into four types: plastic, glass, color changing, and polarizing lenses. Next, let's talk about the lenses made of these four materials.
1: Plastic
Lightweight and non fragile is its most obvious feature. Untreated plastic lenses have significantly better UV protection than glass lenses, and plastic lenses also have simpler color treatment. The disadvantage of plastic lenses is their wear resistance, which makes them more prone to scratches. When the lenses are hit, they are also prone to deformation, so it is important to be more careful in their maintenance.
2: Glass
Glass lenses are something we often come into contact with. The most prominent advantage of glass lenses is their stable optical performance, which is a consistent advantage of glass lenses. The same applies to frame glasses. Additionally, glass lenses are not easily deformed and will not be affected by frame pressure. The disadvantage of glass lenses is that they are prone to breakage, which can cause harm to the eyes. The newly developed reinforced glass lenses have much more outstanding performance than ordinary glass lenses and are also considered a type of safety lens.
3: Color change
Also known as photosensitive lenses, the color of the lens changes correspondingly due to changes in light, allowing the eyes to adapt to different environments. Under strong light, the color of the color changing lens will deepen, and under light, the color of the lens will automatically lighten. This type of lens has been applied to myopia sunglasses, and this color changing lens form of sunglasses is also considered more convenient.
4: Polarization
This is a lens used in polarized sunglasses, which uses the principle of light polarization to block glare from all sources outside the lens, making the line of sight clearer and safer when driving. These materials all have their own characteristics. If you are wearing sunglasses while driving, we recommend using polarizers.
