farsightedness

Farsightedness, or hyperopia, occurs when the eye's shape causes light entering the eye to focus behind the retina instead of directly on it. This makes nearby objects appear blurry, though distant objects may be clearer. It often results from a shorter-than-normal eyeball or a cornea with too little curvature. The eye's focusing muscles work harder to see close-up items, which can lead to eye strain or headaches. Corrective lenses, such as glasses or contact lenses, help refocus light onto the retina, improving clarity for close and distant vision.
