Final answer:
Presbyopia is the correct answer to the student's question about the age-related vision problem where the lens can't bend properly, affecting near vision.
Step-by-step explanation:
Presbyopia is an age-related midlife difficulty with near vision caused by the inability of the lens to bend properly. As one ages, the lens of the eye may become less elastic, and the muscles that control the lens can weaken, leading to difficulties focusing on close objects. This condition usually first becomes noticeable between the ages of 40 and 50. To correct presbyopia, individuals commonly use corrective lenses, such as reading glasses, which contain a converging lens to add power for close vision. Surgical procedures like LASIK can correct distant vision, but they cannot restore the loss of accommodation, which means reading glasses might still be needed.
