sunSMART™ is a true sun-sensitive changeable lens material that easily adapts to a wearer’s environment and not just a traditional changeable coating applied to a plastic lens.
The sun-sensitive particles are infused within the lens material from its liquid state resulting in a consistent photochromic effect throughout the life of the lens and guarantees that the photochromic effect will not wear out or peel-off.
It darkens within seconds when exposed to the sun or UV and deactivates fast to a clear color when indoor. The lens material has high light transmittance and excellent surface quality for a full HD view experience. It passes ANSI standard for optical lenses in terms of precision, quality, and impact resistant tests.
Complete UV-A and UV-B Protection. Highly tintable with the colors you desire or it can be coated with Anti-reflection, Hard-Coat, or Mirror-like coatings for a more stylish finish. You can choose between 2 colors, sunSMART Grey or sunSMART Brown.
