Squinting in bright sunlight helps reduce the amount of light entering the eyes, which can prevent discomfort and glare. This reflex action narrows the eyelids, allowing for better focus and improved visibility in harsh lighting conditions. Additionally, it protects the eyes from potential damage caused by excessive UV exposure.
When you squint after leaving a dark room and entering bright sunlight, the muscles that contract are the orbicularis oculi muscles. These circular muscles around the eyes help to close the eyelids and narrow the opening of the eyes to protect them from the intense light. Additionally, the pupil constricts due to the action of the iris sphincter muscles, further reducing light entry.
