Question

If you look straight at an object when it is nearly

dark, you may find it difficult to see it. It is easier
to see if you look just to one side of it. Explain
why this is

Answer 1

We can better pick up objects by averting our glance rather then viewing the object directly.

Answer 2

Step-by-step explanation:

rod preceptors are more sensitive to dim light than the cones are, which are clustered at the part of retina you use to look at something directly.
