The lens is a flexible structure that changes shape to adjust the focus of light on the retina, enabling clear vision at different distances.

Rods are responsible for low-light vision and peripheral vision, while cones are responsible for color vision and high-acuity vision.

The occipital lobe, located at the back of the brain, is the primary visual cortex and is responsible for processing visual information, including shape, color, and motion.

Stereopsis is the ability to perceive depth and distance based on the slightly different images received by each eye.

Presbyopia is a common age-related condition in which the lens becomes less flexible, making it difficult to focus on nearby objects.

Monochromacy is a rare condition in which individuals can only perceive shades of gray, not colors.

Apparent motion is the illusion of movement created when a series of still images are presented in rapid succession.

The visual system is responsible for detecting light, processing visual information, and interpreting visual stimuli, but it does not produce sound.

Dyschromatopsia is a condition in which individuals have difficulty distinguishing between similar colors, often due to a deficiency in one or more types of cone cells.

The Law of Prägnanz is a principle of Gestalt psychology that states that individuals tend to perceive objects as simple, regular, and symmetrical, rather than complex and irregular.

Spatial orientation is the ability to perceive the orientation of objects in space relative to oneself and to navigate through the environment.

Blinking is a reflex that helps to keep the eyes moist and protected, but it is not a type of eye movement involved in visual perception.

Night blindness, also known as nyctalopia, is a condition in which individuals have difficulty seeing in low-light conditions due to a deficiency in rod cells.

The cochlea is a part of the auditory system, not the visual pathway.

Luminance perception is the ability to perceive the brightness and darkness of objects, allowing us to distinguish between light and dark areas.
