As a specialized OEM/ODM manufacturer of high-performance photochromic lenses, VIIST offers comprehensive custom manufacturing services from optical design to surface treatment. We transform raw materials into intelligent adaptive lenses that automatically adjust to changing light conditions, providing optimal visual comfort and protection.
Photochromic lenses are optical components that automatically darken when exposed to UV radiation and return to clear state when UV light decreases. These light-adaptive lenses contain special molecules (typically silver halides) embedded in the material that undergo reversible chemical changes when exposed to specific wavelengths of light.
