When choosing color-changing glasses, it is mainly considered from the functional characteristics of the lens, the purpose of the glasses, and the individual's color requirements. Photochromic lenses can also be made into a variety of colors, such as gray, brown and so on. Follow the editor of single vision photochromic lens to see how to choose!
1. Gray lens: can absorb infrared rays and 98% of ultraviolet rays. The advantage of a larger gray lens is that it will not change the original color of the scene due to the lens. What is more satisfying is that it can reduce the light intensity very effectively. The gray lens can evenly absorb the color spectrum, so the scene will only become darker, but there will be no obvious chromatic aberration, showing a real and natural feeling. It belongs to the neutral color system, which is suitable for all people.
2. Pink lens: This is a very common color. It can absorb 95% of ultraviolet rays. If it is used as glasses for correcting vision, women who must wear them frequently are recommended to choose light red lenses, because light red lenses absorb ultraviolet rays better and can reduce the overall light intensity, so the wearer will feel more comfortable.
3. Light purple lens: Like pink lens, because of its relatively darker color, it is more popular with mature women.
4. Brown lenses: can absorb 100% of ultraviolet rays, brown lenses can filter out a lot of blue light, can improve the visual contrast and clarity, so it is very popular with wearers. Especially when the air pollution is serious or foggy, the wearing effect is better. Generally, it can block the reflected light from a smooth and shiny surface, and the wearer can still see the subtle parts. It is an ideal choice for drivers. For middle-aged and elderly patients with high vision above 600 degrees, priority can be given.
5. Light blue lenses: Sun blue lenses can be worn when playing on the beach. Blue can effectively filter out the light blue reflected by the sea and sky. We should avoid using blue lenses when driving, because it will make us unable to distinguish the color of the traffic signal.
6. Green lens: The green lens is the same as the gray lens, which can effectively absorb infrared light and 99% of ultraviolet rays. While absorbing light, it greatly increases the green light reaching the eyes, so it has a cool and comfortable feeling, suitable for people who are prone to eye fatigue.
