Question

Visual accommodation occurs when _______________.

a) Too much pressure builds up in the eye
b) The lens changes shape for close vision
c) The lens changes shape for far-away vision
d) The pupil opens wide to let in a lot of light

Answer 1

Visual accommodation occurs when the lens changes shape for close vision to enable the eye to focus on nearby objects.

Step-by-step explanation:

Visual accommodation occurs when the lens changes shape for close vision. In the eye, the lens needs to be more converging for close vision to allow light rays from nearby objects to enter the eye and converge on the retina. The lens becomes thicker through the action of the ciliary muscle surrounding it. This change in the lens shape is called accommodation and it allows us to focus on objects at different distances.
