EYE MODEL, FUNCIONAL

Listing ID #3891179

This unique model permits demonstration of the physical principles upon which the eye operates, including defects of vision and their correction.

The lens and ciliary body are flexible, the lens itself being fluid filled and connected to a syringe. The syring can be used to vary the pressure in the lens and hence its thickness, to simulate accommodation. The length of the ‘eyeball’ may be varied to simulate long or short sight and lenses to be used to demonstrate correction via spectacles.

A major advantage of this model is that actual images may be projected on to the ‘retina’, making it an extremely effective demonstration tool.

The complete model is mounted on a wooden base, and has overall dimensions of 320 x 180mm length x height.
