Claim One:
1. I claim an eye and bonocular vision demonstrator for demonstrating the binocular focus function of vision, Comprising; A casing having upper and lower levels; the lower level having means to hold two simulated eyeballs; A pair of simulated eyeballs, including simulated recti muscles, mounted in the lower level of said casing, said eyeballs each being divided into upper and lower sections, the upper sections being removable and the lower sections containing simulated anatomical features, including lenses; said lenses being secured with rods extending through simulated ciliary muscles butting against the lenses; A means in the rear of the casing for turning the eyeballs inward, simulating convergence; and the inward pressure of said rods pushing against the lenses causing the lenses to change their curvature, thereby simulating focus accommodation.
