Through a series of engaging hands-on, eyes-on experimental activities, your students will not only witness how the human visual organ functions, they will also recreate common visual disorders and discover how to correct them.
Using the Rubin's eye lab they will first demonstrate how crisp, inverted images are projected onto the retina during normal vision (emmetropia.) Next they'll discover how the internal lens of the eye must adjust its focal length in order to bring near objects into sharp focus (accommodation.)
They will go on to reproduce each of the following visual disorders:
Presbyopia (age-related near-vision failure to accommodate)
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.
The self-contained Rubin's Eye Lab package incorporates:
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
Four adjustable supports for positioning components on bench.
Set of five interchangeable color-coded corneal lenses made of impact-resistant optical plastic:
(1) plano lens (clear)
(2) concave lens (pink)
(3) convex lens (gray)
(4 & 5) two astigmatic (toric) lenses (yellow)
Handy lens caddy for stowing corneal lenses
Step-by-step illustrated instructional guide to experiments and additional suggested activities.
