Usage

What does blind mean? Blind is most commonly used to describe a person who is unable to see. It can describe someone who has severe vision impairment or no vision at all. Some people who cannot see may prefer to be described or referred to with terms other than blind. As with all forms of disabilities, it is always best to use the language that the person prefers. The term the blind is sometimes used to collectively refer to people who are blind, such as in the names of organizations like the National Federation of the Blind. However, some people object to such collective uses, which are sometimes thought to prevent people from being viewed as individuals (in contrast with person-first language, such as people who are blind). Blind is sometimes used in figurative ways, especially as an adjective meaning unable or unwilling to accept or perceive something, as in Don’t be blind to the risks. It is also sometimes used to describe something that is not based on logic, as in blind faith. Such figurative uses can be considered a form of ableism due to likening negative characteristics to a physical disability. As a verb, blind can be used in a literal way meaning to temporarily or permanently take away someone’s ability to see, as in I was blinded by the sun or The accident blinded him. As a noun, blind can refer to a number of objects that obstruct vision or light in some way, most commonly window coverings that can be closed to darken a room (typically referred to with the plural form blinds). Example: As a blind person, I want people to remember that just because I can’t see doesn’t mean I’m incapable of living a full life.

Synonym Usage

Blind, stone-blind, purblind mean unable to see. Blind means unable to see with the physical eyes. Stone-blind emphasizes complete blindness. Purblind refers to weakened vision, literally or figuratively. See curtain.

Etymology

Origin of blind

First recorded before 1000; Middle English, Old English adjective cognate with Gothic blinds, Old Norse blindr, German, Dutch blind (from Germanic blindaz, perhaps akin to blend; original sense uncertain, perhaps “to make cloudy”); verb derivative of the adjective

Explanation

Someone who's blind can't see. People who are blind can often get around easily with the aid of a cane and sometimes a service dog. You might get hit by a baseball and end up blind in one eye, or be temporarily blind after a trip to the eye doctor. The word also means "without looking," as in a blind taste test of three different brands of chocolate milk. A figurative way to be blind is to refuse or be unable to see the truth: "He was blind to the reality of the situation." This tendency can be called a person's "blind side."
