Answer to Question 1

Ans: A
These age-related changes decrease responsiveness of the lens and increase the diffusion of light rays, resulting in fewer rays reaching the retina. The most detrimental effect occurs with the shorter blue and violet wavelengths.

Answer to Question 2

Ans: B
Arcus senilis (also called corneal arcus) is evidenced by the development of yellow or gray-white ring around the iris. Glaucoma is related to pressure changes, not changes to the iris. Arthritis is unrelated to eye health. Presbyopia is an age-related visual acuity change.
