The Eye Topic

Anatomical eye model with removable components (lens, iris, vitreous body) for teaching the eye as a compound optical system. Students connect physical structures to their optical functions: corneal refraction, accommodation, …

Models the optics of the human eye on a blackboard using magnetic plexiglass lenses and ray projectors. Students observe normal vision, myopia, and hyperopia by swapping lens combinations, and see …

Students locate their visual blind spot--the region where the optic nerve exits the retina with no photoreceptors. Demonstrates that the brain actively fills in missing visual information rather than passively …

Demonstrates persistence of vision and the stroboscopic effect using rotating patterned disks illuminated by a strobe light. Students observe how discrete images merge into continuous motion or appear frozen, illustrating …

Demonstrates that color perception depends on surrounding context, not just wavelength. The same orange paper appears bright orange against black but brown against white, showing that the brain interprets color …

Two projectors overlay a black-and-white image with a red-filtered image of the same scene. Students perceive blues, greens, and other colors that are physically absent, demonstrating that color vision depends …
