Patent ID: 8765029

Claim:
A method of controlling the optical properties of a polymeric material, said method comprising: (a) identifying a target window in an Abbe diagram; (b) selecting polymeric material having a refractive index and an Abbe number that is outside of the target window; (c) selecting at least one stable UV chromophore; (d) compounding the polymeric material with the at least one stable UV chromophore of step (c), wherein the at least one stable UV chromophore shifts the Abbe number and refractive index of the polymeric material into the target window; and (e) transforming the polymeric material of step (d) into a light transmissive article, wherein the light transmissive article has an Abbe number in a range from about 10 Abbe units to about 32 Abbe units, and wherein the at least one stable UV chromophore is selected from the group consisting of compounds I and II
