visual impairment

This term is the preferred clinical and professional designation used in medical, educational, and legal contexts to describe a wide spectrum of vision loss. It is considered a neutral, objective descriptor that avoids the stigmatizing connotations associated with older terms like blindness or sightlessness.

Because it describes a condition rather than a single state, it is often paired with modifiers such as severe, partial, or profound to specify the degree of vision loss. In administrative or accessibility contexts, it is frequently used to trigger legal protections or the provision of assistive technologies.
