Color changing lenses, also known as photosensitive lenses. Because silver halide chemicals are added to the lenses, the originally transparent and colorless lenses will turn into colored lenses when exposed to strong light for protection, making them suitable for both indoor and outdoor use. In simple and easy to understand terms, it means that under strong light, the silver halides inside turn into black silver particles when exposed to light.
1. Gray lenses: can absorb infrared and 98% ultraviolet rays. The biggest advantage of gray lenses is that they do not change the original color of the scenery due to the lenses, and the most satisfying thing is that they can effectively reduce the intensity of light. Gray lenses can evenly absorb any color spectrum, so when viewing the scenery, it will only darken, but there will be no significant color difference, presenting a true and natural feeling. Belongs to the neutral color scheme and is suitable for use by all groups of people.
2. Pink/light purple lenses: This is a very common color. It can absorb 95% of ultraviolet rays. If it is used as glasses for correcting vision, it is best for women who must wear them frequently to choose light red lenses, because light red lenses have a better absorption function for ultraviolet rays and can reduce the overall light intensity, so the wearer will feel more comfortable.
3. Tea colored lenses: They can absorb 100% of ultraviolet rays, and can filter out a large amount of blue light, improving visual contrast and clarity, making them popular among wearers. Wearing it is particularly effective in severe air pollution or foggy conditions. Generally, it can block the reflected light from a smooth and bright surface, and wearers can still see the subtle parts clearly, making it an ideal choice for drivers. For middle-aged and elderly patients with high vision above 600 degrees, priority can be given.
4. Light blue lenses: When playing on the beach, you can wear sun blue lenses. Blue can effectively filter out the light blue reflected by seawater and the sky. Driving should avoid using blue lenses as they can make it difficult for us to distinguish the color of traffic signals.
