Why do our eyes take time to adjust to the dark after being in a bright room and what is actually happening to help them adjust.
In: 2
Your pupils dilate in the dark to allow more light in allowing you to see more with less light. This is why it hurts your eyes to go from a really dark room directly into sunlight and why it’s important to wear the dark glasses after your eyes have been medically dilated because your dilated pupils are now letting in way too much light for conditions and it takes a minute for your pupils to react and constrict to the new light
