Visual Impairment
Dimension 630 of 1,100 · Health Lens
Visual Impairment measures the presence and impact of problems with seeing, including reduced clarity, light sensitivity, double vision, eye discomfort, and limitations in daily activities that depend on vision. It encompasses both sensory disturbance in the eyes and the extent to which vision problems interfere with functioning and comfort.

Absent Visual Impairment
Expressions activating this band contain little to no clear evidence of vision-related difficulty and are often unrelated to seeing or eye function. When vision is mentioned, it reflects ordinary environmental or daily-life content rather than impairment.
Mild Visual Impairment
Expressions activating this band describe minor or situational visual difficulty, such as trouble reading under challenging conditions or needing some help with visually guided tasks. Vision remains broadly usable, with limitations appearing mainly in specific contexts.
Moderate Visual Impairment
Expressions activating this band describe noticeable visual disturbance centered on sensitivity to brightness and discomfort in strong light. Seeing is intact enough for navigation and everyday activity, but visual comfort is clearly disrupted.
High Visual Impairment
Expressions activating this band describe clear eye or vision problems such as double vision, impaired sight in one or both eyes, painful or itchy eyes, and reliance on corrective devices or magnification. Visual difficulty is persistent and clinically salient.
Severe Visual Impairment
Expressions activating this band describe markedly poor vision that substantially limits work, hobbies, outdoor activity, comfort, or the ability to see clearly even with correction. Vision problems are experienced as strongly burdensome and functionally restricting.
