Your students won’t have to rely on visualization • They’ll actually see how the human eye functions • 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: • Myopia (nearsightedness) • Hyperopia (farsightedness)• 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 •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 • Plano lens (clear) • Concave lens (pink) • Convex lens (gray) • Two astigmatic (toric) lenses (yellow) • Handy lens caddy for stowing corneal lenses • Step-by-step illustrated instructional guide to experiments and additional suggested activities • Overall dimensions: 18Lx41/2Wx8H inches (46x11x20cm)
