Title:

LIGHT ADJUSTABLE LENSES CAPABLE OF POST-FABRICATION POWER MODIFICATION VIA MULTI-PHOTON PROCESSES

Document Type and Number:

WIPO Patent Application WO2005015268

Kind Code:

A3

Abstract:

The invention relates to novel photoinitiators and their use in light adjustable compositions. The initiatives comprise two or more multiphoton chromophores linked by a bridging compound. The bridging compound consists of a material that is compatible with the base material of the light adjustable composition. The novel photoinitiator permit the readjustment of light adjustable material without the need for significant amounts photoasorbers.
