Photochromic compositions of improved fatigue resistance |
| abstract |
Photochromic optical articles of improved resistance to light fatigue are provided by the use of a combination of hindered amine light stabilizer and asymmetric diaryloxalamide light stabilizer with a mixture of (1) photochromic material having a minima luminous transmission in the range of 560 to 630 nanometers and (2) photochromic material having a minima luminous transmission in the range of 430 to 520 nanometers. |
