Final answer:
Hideki is experiencing presbyopia, a condition where the eye's lens loses elasticity, impairing near focus due to aging. He would typically need corrective lenses, such as reading glasses, to see close objects clearly.
Step-by-step explanation:
Condition Hideki Has
Hideki has presbyopia, a common vision problem associated with aging. This condition is characterized by a gradual loss of the eye's ability to focus on close objects due to the lens losing elasticity. In Hideki's case, since the muscles controlling his lens may also lose power, he's experiencing difficulty in focusing, which is why he may need corrective lenses to improve his near vision.
Correcting Presbyopia
To correct presbyopia, individuals typically use reading glasses or other corrective lenses. This is because the lens inside the eye can no longer accommodate or change its shape enough to focus on near objects, resulting in blurred vision for close-up tasks. Surgical procedures have not been as successful for presbyopia as for other vision problems like myopia or hyperopia, so corrective lenses remain the primary solution.
