Photo-responsive shape changing polymer composition for colored optical lens

A photo-responsive colored shape changing polymer composition comprising:

• a) a photoinitiator that absorbs light in the wavelength range of about 400 nm to about 700 nm;
• b) a cross-linked polymer matrix;
• c) a polymerizable composition;
• wherein, exposing the photo-responsive colored shape changing polymer composition to a photobleaching dose of light, in the wavelength range of about 400 nm to about 700 nm, photobleaches the photo-responsive colored shape changing polymer composition such that its maximum absorbance in the visible wavelength region is decreased by at least about 50% from its value prior to exposure to the photobleaching dose of light.

A colored intraocular lens comprising:

• a) photoinitiator that absorbs light, in the wavelength range of about 400 nm to about 700 nm,
• b) a cross-linked polymer matrix, and
• c) a polymerizable composition;
• wherein, the colored intraocular lens can be photobleached by exposing the colored intraocular lens to a photobleaching dose of light in the wavelength range of about 400 nm to about 700 nm, such that the maximum absorbance of the colored intraocular lens in the visible wavelength region is decreased by at least 50% from its value prior to exposure to the photobleaching dose of light in the wavelength range of about 400 nm to about 700 nm.
