How the Eye Functions, 1941

This 1941 Knowledge Builders film dissects the human eye’s structure in black-and-white with sound, detailing how light waves refract through the lens to focus on the retina. It zooms in on the lens—its position and curvature shifts—while exploring monocular and binocular vision. Diagrams likely animate the retina’s role and light’s path, offering a clear, pre-WWII primer on ocular mechanics for classrooms, blending gross anatomy with fine details in a concise scientific showcase.
