Vision Concepts
- Binocular Vision: Ability to see one image using both eyes.
- Rods: Receptor cells in the retina responsible for peripheral vision.
- Fovea Centralis: Area of sharpest vision in the eye.
Light and Eye Structures
- Refraction: Bending of light rays as they pass through the eye structures (cornea, lens) towards the retina.
- Iris: The colored part of the eye.
- Pupil: Dark opening at the center of the iris.
