Answer to Question 1

ANS: A
Signs of cataracts include the appearance of halos around objects as light is diffused, blurring, decreased perception of light and color giving a yellow tint to most objects, and a sensitivity to glare.

Answer to Question 2

ANS: A
A slowed ability of the pupil to accommodate to changes in light accounts for the need of this patient to have more light in order to read. Arcus senilis does not affect vision. It is true that the cornea becomes flatter and thinner with aging, which results in astigmatism. Astigmatism does not account for the need for increased light that this patient is reporting. The changes in the retina do not account for the need for increased light that this patient is reporting.
