Abstract:
1. A prosthetic eye having a light responsive pupil comprising: (a) a body of the prosthetic eye, the body having an internal cavity with an opening; (b) an annular iris comprising a photoresponsive, polymer based element in the opening of the body, an inner radius of the iris defining the pupil; and (c) a transparent cornea covering the opening in the body to enclose the iris, wherein when the iris is exposed to light the photoresponsive, polymer based element expands so as to constrict the pupil in response to the light, wherein the body is spheroid or disc shaped, and wherein the photoresponsive, polymer based element mechanically deforms when illuminated by light such that the iris expands in the presence of light and contracts in the absence of light.
