Ocular response refers to the way the eyes react to various stimuli, such as light, movement, or changes in the environment. This response is crucial for vision and involves several components, including the pupil, which adjusts size to control the amount of light entering the eye, and the retina, which processes visual information. The ocular response can also include reflex actions, such as blinking when an object approaches the eye or the accommodation process, where the lens changes shape to focus on objects at different distances. These responses help protect the eyes and enhance visual clarity.
