Eye Demo

An eye model is available to demonstrate how vision works. Focus can be demonstrated by using the attached syringes to adjust the volume of fluid in the lens. Far-sightedness and near-sightedness can be demonstrated by adjusting the distance between the back of the model and the lens.  A set of corrective lenses can be used to demonstrate how glasses can fix eyesight problems. For large classrooms, vi deo equipment is used to allow classroom viewing.
