ABSTRACT:
A prosthetic eye has a white scleral portion with a simulated iris painted on the front and a horizontal polarized disc at the center of the iris. The center of the polarized disc is darkened with paint to simulate a pupil having a fairly small diameter. The back of the polarized disc is painted to blend with the iris or simulate the collarette of the eye. The prosthetic eye is used in conjunction with the special pair of eyeglasses having a lens formed of linearly polarizing material with the transmitting axis in the vertical plane. When the eyeglasses are used, it makes the pupil appear to dilate because it causes the entire disc to blacken when viewed through the polarized lens.
