Visual Impairment (VI)

Visual impairment (VI) refers to a significant reduction in vision that cannot be corrected with standard glasses, contact lenses, medication, or surgery. This includes conditions such as low vision and blindness, which can impact a person's ability to perform everyday activities. Additionally, color blindness is considered a form of visual impairment, affecting how individuals perceive colors.
