The pupil of our eye contracts in bright light as a protective response to prevent excessive light from entering the eye and damaging the retina. This process is controlled by a reflex called the pupillary light reflex
The eye in many ways is like a camera. The camera’s aperture is the part that expands and contracts to let in more or less light. The pupil works in a similar fashion.
It will get very small in bright light to physically block the amount of light reaching the retina and will open wide in the darkness. This helps to protect the retina and process the image better.
The pupil contracts in bright light to protect your eyes from too much light. The iris makes the pupil smaller, reducing the amount of light that reaches the retina. This helps improve vision in bright conditions and protects the eye from glare. If your pupils don’t respond normally to light or you notice sudden changes in vision, it’s best to consult an eye specialist.
