1.56 Photo Colorful HMC Optical lenses
Photochromic lenses, also known as “photosensitive lenses”. According to the principle of light-color interconversion reversible reaction, the lens can quickly darken under the irradiation of light and ultraviolet rays, block strong light and absorb ultraviolet rays, and absorb visible light neutrally; when it returns to the dark place, it can quickly restore the colorless and transparent state, ensuring the lens of transmittance. Therefore, photochromic lenses are suitable for both indoor and outdoor use to prevent damage to the eyes from sunlight, ultraviolet light and glare.

1.56 FSV Photo Gray HMC Optical lenses
Photochromic lenses not only correct vision, but also resist most of the damage to the eyes from UV rays. Many eye diseases, such as age-related macular degeneration, pterygium, senile cataract and other eye diseases are directly related to ultraviolet radiation, so photochromic lenses can protect the eyes to a certain extent.
Photochromic lenses can adjust the light transmittance through the discoloration of the lens, so that the human eye can adapt to the change of the ambient light, reduce visual fatigue and protect the eyes.
