Abstract
A rewritable and freezable lens and method for manufacturing thereof are disclosed. This lens includes at least one active element that has optical properties that can be written, frozen and rewritten into new values at least twice. Rewritable and freezable lenses comprising active index polymer dispersed liquid crystal materials are disclosed. In-situ re-adaptation of spectacle and contact lenses is possible at the point of sale. In-vivo re-adaptation of intraocular lenses in the doctor's room is feasible, avoiding further surgery.
