Pupil size changes because two sets of smooth muscles in the iris control how much light enters the eye. One set of muscles forms a circular band around the pupil. When these circular muscles contract, the pupil becomes smaller. This happens in bright light to protect the retina from excessive illumination. The contraction is controlled by parasympathetic signals that tell the muscles to tighten. The second set of muscles lies in a radial pattern, extending outward from the pupil like spokes. Wh

Have you ever seen on TV when a doctor shines a pen light into someone’s eyes to check if they’re okay? That’s not just “eye stuff.” That’s a brain test. 👁️ It’s called the pupillary reflex test. Believe it or not, the speed of how quickly your pupil can constrict, dilate, and hold tells us a lot about how your brain and nervous system are functioning. And sometimes it reveals what spreadsheets can’t: whether your system is overstressed whether your brain is fatiguing too fast whether deeper pa

@medicalstudent.io on Instagram: "The pupil is the dark circle in the center of the eye that controls how much light enters. It changes size automatically to protect the eye and help with clear vision. When it dilates, it becomes larger to let in more light, and when it constricts, it becomes smaller to reduce light entry. Pupil dilation happens in dim light or darkness so that more light can reach the retina and improve vision. It can also occur when a person feels excited, afraid, or focused,
