ABSTRACT:
The invention provides a crosslinkable or polymerizable optical material that is suitable for producing a biocompatible holographic optical element. The optical material is a rapidly crosslinking or polymerizing material that changes from a fluid state to a solid state with in a limited duration after being exposed to a light source.
