Abstract

Intraocular lenses are manufactured with a higher concentration of blue light blocking chromophores at the center of the lens than at the periphery. Manufacturing involves creating a core by polymerization having a higher concentration of the blue light blocking chromophores, and then polymerizing around the core material a polymer sleeve or tube containing a lesser amount of chromophore. In the second polymerization step some of the chromophore migrates from the higher concentration core to the lesser concentration perimeter material, creating a uniform gradient.
