Answer 1

Answer:

When you are in the dark, the pupil gets dilated to allow more light into the retina so that you can see. ... When you are in a bright room, the pupil has constricted itself, and on sudden darkness, it would take certain time for the pupil to dilate so that you will be able to see.

Answer 2

Answer:

when we move into the dark room from bright light the eyes need time to adjust and both cones and rods participate in dark adaptation ,slowly increasing their sensitivity to light in dark environment ,cones adapt faster ,so the first few minutesof adaptation reflect cones meditated vision. Rods work slower at much lower level of illumination they take over after the initial cone meditated adaptation method.
