Answer #2

1. Which of the following is important for dark adaptation?

the answer is a) Constriction of the pupil because when we contract pupil means we dilate the pupil and it gets bigger so that it allows more lights to enter into eyes in darkness so that sensitivity is enhanced. with this, the sensitivity of rods and cones in eyes also helps in dark adaptation.

Remaining options like b. Increase the convexity of lens and c. Diversion of both eyes will not help in dark adaptation.
