See clearly day and night with Photochromic Technology
The Erythraean lenses contain special crystals that darken when exposed to sunlight. At night when the UV light diminishes, the lenses fade back. As light conditions change, the level of tint adjusts, offering the right tint at the right time.
The rate of discoloration is related to the intensity of ultraviolet light and the temperature.(if UV intensity and temperature is low, The speed of discoloration will become slower).
The Erythraean lens is made of Polycarbonate. This material is so resistant that is used in bulletproof glass, riot shields, and even astronaut helmets.
