Ocular components refer to the various parts of the eye that work together to enable vision. Key components include the cornea, lens, retina, and iris. The cornea and lens help focus light onto the retina, which contains photoreceptor cells that convert light into electrical signals. These signals are then sent to the brain via the optic nerve. Each ocular component plays a specific role in the visual process. The iris controls the amount of light entering the eye by adjusting the size of the pupil. Proper functioning of these components is essential for clear vision and overall eye health.
