Which term refers to not having a functional use of sight?

• A. Visual Impairments
• B. Low Vision
• C. Blindness
• D. Total Darkness

Answer: (C)

Not having a functional use of sight is described as blindness. This label means that vision cannot be relied upon for everyday tasks or learning, even with typical correction, so the individual uses other senses and supports to participate. Visual impairment is a broad category that includes any degree of vision loss, while low vision refers to substantial vision loss but with some usable sight remaining. Total darkness is not a clinical or educational term for a person’s vision status; it’s just a condition of the environment, not a descriptor of functional vision.
