Question
When we migrate from dark to light, we fail to see for some time but after a time visibility becomes normal. It is an example of
Options
A.accommodation
B.adaptation
C.mutation
D.photoperiodism
Solution
It takes some time for rhodopsin to split into scotopsin and retinal (bleaching) and release of transmitter passing nerve impulse via bipolar and ganglion cells to the optic nerves. This is a case of adaptation. It differs from accommodation which is a reflex mechanism by which the focus of the eye change to make the images of distant and near objects sharp on the retina.
