Your student's won't have to rely on visualization -- they will actually see how the human eye functions with the Rubin's Eye and Vision Lab.
Through a series of engaging hands-in, eyes-on experimental activities, you students will not only witness how the human visual organ functions, they will also recreate common visual disorders and discover how to correct them.
The eye lab will demonstrate how crisp, inverted images are projected onto the retina during normal vision (emmetropia). Then they discover the how the internal lens of the eye must adjust it's focal length in order to bring near objects into sharp focus. (accomodation).
They will be able to reproduce the following visual disorders:
- Myopia (nearsightedness)
- Hyperopia (farsightedness)
- Presbyopia (age related near vision failure to accomodate)
- Astigmatism (blurred or distorted vision at any distance due to irregular corneal curvature)
For each disorder your students will in turn have to implement appropriate corrective steps -- reinforcing the learning experience as they do so.
This self-contained Rubin's Eye Lab comes complete with:
- An optical bench with track and indicator markings for experimental repeatability
- Object slide holder
- Anterior eye hemisphere with integral corneal lens holder and patented trigger - focusable internal lens
- Posterior eye hemisphere with retina
- Long life halogen light source (20W, 115V, 50/60 Hz)
- Four adjustable supports for positioning components on bench
- Set of five interchangeable color-coded corneal lenses made of impact-resistant optical plastic
- Clear plano lens
- Pink concave lens
- Grey convex lens
- Two yellow astigmatic (toric) lenses
- Handy lens caddy for stowing corneal lenses
- Step-by-Step illustrated instructional guide to experiments and additional suggested activities
