1. when we enter a dim light room from a bright light, we're not able to see the object for sometime. explain why2. why do we have two eyes Instead of one​

Answer»

Answer:

1. It takes some time to see objects in a dim or dark ROOM when we ENTER the room from the bright sunlight outside because in bright sunshine the pupil of our EYE is small. HENCE, as we enter a dim room, very little light enters our eyes and we can't see properly.

2. We need two eyes because a human being has a horizontal field of view of about 150° with one eye and of about 180° with two eyes. Thus, two eyes provide us wider horizontal field of view. With one eye, the world looks flat, i.e., two DIMENSIONAL only.
