1. grandmother holds her hand 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

Explanation:

For question 27, in nearsightedness (myopia), the eye is too long or the refractive power is too strong, causing light rays to focus in front of the retina instead of directly on it. For question 28, presbyopia (loss of near - point accommodation with age) is mainly due to the loss of lens flexibility over time, which reduces the eye's ability to change its shape to focus on close objects.

Answer:

1. C. in front of the retina
2. D. loss of lens flexibility
