Question

Kavya comes out of the cinema hall, she experiences a glare in her eyes. She is not able to understand the reason for the same
Can u explain why ?

Answer 1

This is because a cinema hall views the cinema in a dark room and a wide screen. This is also the principle which is applicable in pinhole camera. She experiences the glare because the retina of the eye needs time to adjust with real light in the outer room after coming from the cinema hall which was dark.
