What Are Eye Focusing Problems?
Eye focusing problems occur when the eyes cannot adjust properly to keep images clear at different distances. The focusing system, controlled by the lens and its surrounding muscles, may struggle with near tasks, distance tasks, or both. Refractive errors like nearsightedness and farsightedness affect how light focuses on the retina. Age related changes cause presbyopia, which makes reading difficult. Focusing issues can affect children and adults and often cause eye strain or headaches.
