Reflective Polarized Lenses With High Transmission
The present invention relates to unique reflective polarized lenses that are anti-dazzling and reduce glare. In particular, it relates to polarized lenses utilizing a reflective polarizer, a high-transmission absorptive polarizer and photochromic treatment in a unique combination that can be injection molded to make thermoplastic ophthalmic lenses. The resulting lenses have high luminous transmission, high polarization efficiency for use in sunglasses and has potential applications for night vision
