Claim:
1. A simulated eye, comprising a transparent, one-piece structure, made from a material having an index of refraction of about 1.49, forming a cornea portion, a positioning band, and a scleral band connecting the cornea portion and positioning band, the cornea portion having a convex external surface, an internal surface, and a thickness defined therebetween, the cornea portion further defining a central section corresponding to a front of the simulated eye and an edge corresponding to a side of the simulated eye, the thickness being greatest within the central section and tapering towards the edge, the internal surface of the cornea portion having coloring thereon to resemble an iris and pupil, the cornea portion's thickness around its edge and the thickness of the central section having a ratio of about 0.25 to about 0.7, the cornea portion having a maximum thickness of about 20% to about 33% of an external diameter of the cornea portion; whereby a viewer viewing a portion of the simulated eye will view the pupil appearing to be oriented generally towards the viewer regardless of whether the viewer views the simulated eye from the front, the side, or from a position between the front and side.
