Quizplus · Accepted Answer

Presbyopia is a form of farsightedness that often develops in individuals in their 40s or 50s due to the loss of flexibility in the lenses of the eyes that occurs with age. Myopia is the opposite condition, also known as nearsightedness. Astigmatism is a different type of vision problem where the cornea is misshapen, causing blurry vision at all distances. Hyperopia is another term for farsightedness, but it typically refers to a different type of farsightedness that develops earlier in life and is caused by the eyeball being too short.
