Answer:
When one enters a dim lit room from bright sunlight, it takes some time to see the objects, due to the fact that, in bright sunlight the pupil of our eye is small. So, when we enter the dim lit room, very little light enters our eye and we are unable to see properly.

Answer:
cuz our iris regulates the entrance of light in eyes it expands in less light and contracts in excess light but this expansion and contraction take some time so that when we enter from sunshine to a dark room we can't see clearly
