Eye and Vision Lab
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.
