Final answer:
The vision change not associated with aging is the increase in nearsightedness and decrease in farsightedness. Aging typically causes farsightedness to become more pronounced due to presbyopia, which is the loss of the eye's ability to focus on close objects.
Step-by-step explanation:
The vision change that is NOT associated with aging is 'Nearsightedness increases while farsightedness decreases' (option b). As we age, the opposite typically occurs: nearsightedness (myopia) does not necessarily increase, and farsightedness (hyperopia) tends to become more pronounced. This is because the eye's lens loses its ability to change shape and focus on nearby objects, a condition known as presbyopia, which often necessitates the use of reading glasses. This is why people over 55 often need reading glasses; their lens no longer focuses correctly, and images may focus behind the retina for close objects.
Moreover, individuals with presbyopia who correct their distant vision with LASIK or similar procedures will still typically need reading glasses for near tasks. The LASIK procedure corrects the corneal shape for clear distant vision but does not address the lens's diminished flexibility for close vision.
