उत्तर
- A person from the bright sunlight outside enters a poorly lit room and feels blinded for a short while due to dark adaptation.
- Dark adaptation includes regenerating rhodopsin, a pigment in rod cells that breaks down in strong light.
- The pupils dilate, allowing more light into the eyes.
- Adjustments can be time-consuming and may cause temporary blindness.
