What visual condition is characterized by the inability to focus on nearby objects?

The main idea here is how the eye’s focus for near objects changes with age. Presbyopia is the age-related loss of accommodation—the eye’s ability to increase its optical power to focus on close things. As the lens becomes less flexible and the ciliary muscle less able to change its shape, you can no longer bring near print into sharp focus. This is why many people in their 40s and beyond notice difficulty reading small print and may need reading glasses or progressive lenses. To connect this to the other conditions: myopia is trouble seeing distant objects clearly because distant light focuses in front of the retina; hyperopia is trouble with near tasks because the eye’s focusing is biased toward requiring more accommodation to bring near objects into focus; astigmatism causes blurred vision at multiple distances due to irregular corneal curvature. Presbyopia sits in a different category as an age-related decline in near focusing, rather than a fixed refractive error present from birth or a corneal shape issue.
