Ryders Photochromatic
Protection from the Sun
Powered by the Sun
Science that works like magic.
The scientific explanation: These photochromic lenses contain millions of molecules that are transparent in the absense of UV light. When these molecules are exposed to UV rays, as in direct sunlight, they undergo a chemical process that changes their shape. The new molecular structure absorbs some of the visible light causing the lenses to darken. The number of molecules that change shape increases as the UV grows in intensity, therefore, the brighter the sunlight, the darker the lenses. Photochromic glassses take time to change from light to dark and back again, and are therefore ideal for activities where changes in sunlight are gradual. So, no matter what the day throws at you, you'll be seeing it in the best light.
Developed in France by world leader Essilor, and incorporating their patented Active Cell Technology. Ryders Photochromic lenses are optically correct.
