Flexibility of the lens in the human eye allows the lens to

Grandmother holds her and at arms length to detect a thorn in her finger tip. When she was a young girl, she could easily see the thorn at 25 cm. The loss of near-point accommodation with increasing age is most likely due to

a) inability of the iris to adjust to changing light conditions
b) loss of light sensitivity of the rods and cones
c) uneven curvature of the cornea
d) loss of lens flexibility

Flexibility of the lens in the human eye allows the lens to

a) bend to focus the image in front of the retina
b) change shape to focus both near and distant objects
c) relax and contract to protect the retina from excess light
d) move forward or backward to control the amount of light striking the retina

Please and Thank you!
