About This Product
This kit links the anatomy of the eye with the optics of vision. Students take the model apart to follow light from the cornea to the retina, then move to the bench to see an image focus in front of or behind the retinal screen, and watch a corrective lens bring it back into focus. It suits biology and physics practicals on the human eye and its defects. Laboratories and colleges in Chad, Chile, Madagascar, Portugal, Guinea-Bissau and Fiji can buy the Eye and sight through an export order.
Frequently Asked Questions
Which eye defects can the Eye and Sight kit show?
It simulates normal vision, myopia (near-sightedness), hyperopia (far-sightedness) and astigmatism, and shows correction with concave, convex and cylindrical lenses placed in the light path.
Does the demonstration need a dark room?
Ray paths and the image on the retinal target screen are clearest in a darkened room or under dimmed lighting.
