This is the perfect model to educate patients in astigmatism, myopia, and hyperopia. Use the sliding beads to demonstrate the focal length of the eye in different meridians.

This eye model also shows a cross section of the eye in three layers: the retina, choroid, the sclera with veins and arteries. It is made of plastic, it measures 6 inches in diameter, and it is mounted on a white, opaque plastic base. It is realistically colored and textured. The cornea, optic nerve, and insertion of muscle are shown.
