A condition where distant objects appear blurry while close objects can be seen clearly, often due to the shape of the eye.
He was diagnosed with nearsightedness and needed glasses to see the board in class.
Nearsightedness is formed from "near" (from Old English "neah", meaning close) and "sight" (from Old English "sīht", meaning the ability to see) combined with the suffix "-edness" (indicating a state or condition). The term refers to the condition of being able to see objects clearly only when they are close, but not at a distance.
Think of being able to see things that are 'close' ('near') clearly, while things that are far away are not as clear, which is what nearsightedness describes.
