How to choose a color-changing lens

When choosing color-changing glasses, we mainly consider the functional characteristics of the lenses, the use of the glasses and personal requirements for color. Photochromic lenses can also be made into many colors, such as gray, brown and so on.

1, gray lens: can absorb infrared rays and 98% ultraviolet rays. The biggest advantage of gray lens is that it will not change the original color of the scene because of the lens, and the most satisfactory thing is that it can effectively reduce the light intensity. Gray lenses can evenly absorb any color spectrum, so the scenery will only darken, but there will be no obvious color difference, showing a true sense of nature. It belongs to neutral color system and is suitable for all people.

2. Pink lenses: This is a very common color. It can absorb 95% ultraviolet rays. If it is glasses for correcting eyesight, it is best for ladies who must wear them often to choose reddish lenses, because reddish lenses have better absorption function for ultraviolet rays, which can reduce the overall light intensity and make the wearer feel more comfortable.

3. Light purple lenses: Like pink lenses, they are more popular with mature women because of their relatively dark colors.

4.tan lens: It can absorb 100% ultraviolet rays, and can filter out a lot of blue light, which can improve visual contrast and clarity, so it is deeply loved by wearers. Especially in the case of serious air pollution or fog, the wearing effect is better. Generally, it can block the reflected light from a smooth and bright surface, and the wearer can still see the subtle parts clearly, which 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: You can wear sunglasses when playing on the beach, and blue can effectively filter out the light blue reflected by sea and the sky. We should avoid using blue lenses when driving, because it will make us unable to distinguish the color of traffic signals.

6. Green lenses: Like gray lenses, green lenses can effectively absorb infrared light and 99% ultraviolet light. While absorb light, that green light reaching the eye is increased to the maximum extent, so that it has a cool and comfortable feeling, and is suitable for people with easily tired eyes.

7. Yellow lens: It can absorb 100% ultraviolet rays and let infrared rays and 83% visible light pass through the lens. The biggest feature of yellow lens is that it absorbs most of the blue light. Because when the sun shines through the atmosphere, it is mainly blue light (which can explain why the sky is blue). Yellow lenses can make natural scenery clearer after absorbing blue light. Therefore, yellow lenses are often used as "filters" or used by hunters when hunting. Strictly speaking, this kind of lens does not belong to sunglasses, because it hardly reduces visible light, but in foggy days and dusk, yellow lens can improve contrast and provide more accurate visual images, so it is also called night vision goggles. Some young people wear yellow lenses "sunglasses" as decoration, which is an option for glaucoma performers and patients who need to improve their visual brightness.

With the demand of modern life, the role of colored glasses is not only to protect the eyes, but also a work of art. A pair of appropriate colored glasses and appropriate clothing can set off a person's extraordinary temperament.
