When we migrate from dark to light, we fail to see for sometime but after a time visibility becomes normal. It is an example of:

1. accommodation
2. adaptation
3. mutation
4. photoperiodism

Correct answer: adaptation

Solution

The eyes gradually adjust their sensitivity when lighting conditions change, so vision is poor at first and then returns to normal. This reversible adjustment is an example of adaptation, not accommodation, mutation, or photoperiodism.
