Which of the muscles contracts when you squint after leaving a dark room and going into the bright sunlight?
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.
