Is myopia a medical term which is only used in medical and professional context? Or can it be used in colloquial conversation? The question also leads to another question: is there any popular and colloquial synonym of myopia?
The colloquial synonym is nearsightedness or shortsightedness. Any of the three terms can be used figuratively to mean "not prepared for the future" or "unable to anticipate what will happen". That said, shortsighted is by far the most common term to be used figuratively, and nearsighted is the most common term to be used literally when speaking colloquially about the medical condition.
