  • On-demand photoinitiated polymerization
    Patent number: 8933143
    Abstract: Compositions and methods for adjustable lenses are provided. In some embodiments, the lenses contain a lens matrix material, a masking compound, and a prepolymer. The lens matrix material provides structure to the lens. The masking compound is capable of blocking polymerization or crosslinking of the prepolymer, until photoisomerization of the compound is triggered, and the compound is converted from a first isomer to a second isomer having a different absorption profile. The prepolymer is a composition that can undergo a polymerization or crosslinking reaction upon photoinitiation to alter one or more of the properties of the lenses.
    Type: Grant

    Date of Patent: January 13, 2015
    Assignee: California Institute of Technology
    Inventors: Andrew J. Boydston, Robert H. Grubbs, Chris Daeffler, Nebojsa Momcilovic
