What does nearsightedness mean?
Nearsightedness is the formal term for myopia, a refractive condition in which distant objects appear blurred while nearby objects are generally easier to see. It commonly develops during childhood, although its severity can change with age. Corrective lenses and other refractive treatments can improve vision. The word is also used figuratively for a failure to consider future consequences, possible risks, or effects beyond the immediate situation. In that extended sense, it describes limited foresight rather than an eye disorder. The expression “nearsighted” is more common when referring to a person, while “nearsightedness” is especially useful in medical, educational, and formal discussions about vision. It should not be confused with presbyopia, the age-related loss of the ability to focus on nearby objects.
The condition of being unable to see distant objects clearly; myopia.
"Corrective lenses helped reduce the effects of his nearsightedness."
A lack of foresight or attention to likely future consequences.
"The policy was criticized for its political nearsightedness."
The plural is uncommon because the condition is usually discussed in the singular or as a mass noun. Use it when referring to distinct instances or degrees of the condition.
"The study compared the nearsightednesses of children with different levels of outdoor activity."
Nearsightedness puts the world in focus, just not where your eyes expect to find it.

Where does nearsightedness come from?
The word is formed from the combining form near-, meaning close, and sightedness, meaning the condition of having sight or being able to see. Its ultimate root is the Old English sihþ, meaning sight or vision, which is cognate with forms such as German Sicht and Dutch zicht. The compound entered modern English during the 19th century, alongside the widespread use of the adjective nearsighted.
