Photochromic Lenses, High-Definition Gray Optical Lenses

Photochromic lenses are suitable for various environments, especially in environments with strong sunlight. For example, when exposed to ultraviolet and short wave visible light under sunlight, the lens will darken and reduce light transmittance; In indoor or dark environments, the light transmittance of the lens will increase, restoring its transparent state. This automatic adjustment feature can reduce visual fatigue and protect the eyes from the harm of sunlight, ultraviolet rays, and glare.

Characteristics of photochromic lenses Adaptive lighting

Photochromic lenses automatically change color when exposed to ultraviolet light to resist the effects of glare. After being removed from the ultraviolet environment, the lens will return to a transparent state. This automatic adjustment feature eliminates the need for users to manually replace lenses or perform other operations, making it very convenient to use. Its working principle is to add photochromic dyes inside the lens, which undergo molecular structural changes under the action of ultraviolet light, thereby changing the color and transparency of the lens.

Characteristics of photochromic lenses High transparency

Although photochromic lenses darken their color during color change, their transparency does not significantly decrease. This is because the manufacturer uses high-quality resin materials and advanced optical technology to ensure high transparency and clarity of the lenses. Compared to other lenses, photochromic lenses have even higher transparency, providing a better visual experience
