Question

which of the following statements regarding visual changes in midlife is true?the number of rods and cones stays the same, but they function less effectively.the lens of the eye gets smaller and more transparent.vision changes are minor and very few middle adults require glasses.an operation can be performed to correct problems with distance vision.

Answer 1

True visual changes in midlife include the decline in rods and cones functionality and the lens becoming less flexible, leading to conditions such as presbyopia. LASIK surgery can correct distance vision, but reading glasses may still be needed for close work. Therefore correct option is A

Step-by-step explanation:

Regarding visual changes in midlife, the statement that is true is that the number of rods and cones stays the same, but they function less effectively. Over time, the lens of the eye can become harder and less flexible, leading to conditions such as presbyopia, which affects the ability to focus on close objects. This condition is a result of the lens losing its ability to accommodate or change shape to focus on nearby items, necessitating the use of reading glasses or other corrective measures. Operations like LASIK can correct problems with distance vision, but they do not address the loss of accommodation due to presbyopia, meaning middle-aged adults may still require reading glasses even after such procedures.
