The main function of glasses for us is to block ultraviolet rays, which greatly increases the probability of developing cataracts. The strength of UV protection is not related to the color of our lenses but to the material and film layer of the lenses. All of the above colors should have a UV 380 or higher defense ability, otherwise, they should be replaced even if the color is darker.
The function and effect of sunglasses with different color lenses.
Brown lenses: Filter out a large amount of blue light, which can improve visual contrast and clarity. Wear them effectively in severe air pollution or foggy conditions. Generally, it can block the reflected light from a smooth and bright surface, and the wearer can still see the subtle parts clearly, making it an ideal choice for drivers.
Silver lenses: The surface of the lenses is coated with high-density mirror coating. This type of lens absorbs more reflected visible light and is suitable for outdoor sports enthusiasts.
Baby blue, light pink, and other lenses: they are also more decorative than practical.
Dark green lenses: Absorb hot air and bring a refreshing feeling, but with low transparency and clarity, suitable for wearing in the sun, not when driving.
Blue lenses: You can wear sun blue lenses when you play on the beach. Blue can effectively filter out Baby blue reflected by sea water and sky. Driving should avoid using blue lenses, as they can make it difficult for us to distinguish the color of traffic signals.
Transparent lenses: Transparent lenses actually have a slight yellow color, and are called transparent lenses because they are relatively light. Can be used as a windshield or rainproof mirror.
