3D Eye Anatomy and Image Formation
Explore a full cross-section with 16 types of interactive structures. Use a fixed image plane to compare normal vision, refractive and axial myopia or hyperopia, and their correction.
What to exploreExplore eye anatomy, light paths and refraction.
Explore an eye cross-section and compare the lens, retina and light paths in the same scene. Switch refractive conditions to observe the focal position relative to the retina.
Using it in classCompare focal positions and explain vision correction.
For projected demonstrations of eye anatomy, lens accommodation, the inverted retinal image, focal positions in front of or behind the retina, and correction with glasses.
Start by identifying structures along the light path. Compare normal vision, myopia and hyperopia, then use the correction demonstration to explain the role of glasses.
