Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it.
Mark was having trouble seeing things up close when he was reading. Menu or books even files at the office had to be held as far away as possible so he could read.
Will conves lenses focus images further back or forward on his retina?
