Quizplus · Accepted Answer

The symptoms of impaired visual acuity and color vision in both eyes, along with difficulties reading even with powerful reading glasses, suggest macular degeneration. Additionally, the fact that Harry's peripheral vision is unimpaired helps to rule out other conditions like retinitis pigmentosa or cataracts. Heterochromia is a condition where individuals have different colored irises in each eye, which is not the case with Harry.
