---
Photochromic: These are clear eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Other terms sometimes used for photochromic lenses include "light-adaptive lenses," "light intelligent" and "variable tint lenses."
How photochromic lenses work: The molecules responsible for causing photochromic lenses to darken are activated by the sun's ultraviolet radiation. Because UV rays penetrate clouds, photochromic lenses will darken on overcast days as well as sunny days.
TR-90 Frame: TR90 was produced through Swiss technology as a thermoplastic material that is incredibly durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable.
UV-400: 'UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.
