Visual reflexes are automatic responses of the body to visual stimuli. These reflexes help protect the eyes and maintain focus on objects. For example, when a bright light shines in the eyes, the pupils constrict to limit the amount of light entering, preventing damage to the retina. Another common visual reflex is the blink reflex, where the eyelids close quickly in response to a sudden object approaching the eye. This reflex helps prevent injury by shielding the eyes from potential harm. Overall, visual reflexes play a crucial role in maintaining eye health and enhancing visual perception.
