Light Sensitivity
Dimension 143 of 1,100 · Health Lens
Light Sensitivity measures how strongly an expression reflects sensory discomfort, annoyance, or aversion in response to bright light, sunlight, glare, and closely related visual environmental conditions. It encompasses both heightened reactivity to brightness and preferences or avoidance patterns shaped by that reactivity.

Absent Light Sensitivity
Expressions activating this band do not show a coherent pattern of brightness-related sensory reactivity and are largely unrelated to light-based discomfort or visual environmental sensitivity.
Mild Light Sensitivity
Expressions activating this band show early or situational sensitivity to sensory input, including distraction, discomfort, or caution around environmental stimulation, with occasional references that touch visual or perceptual reactivity.
Moderate Light Sensitivity
Expressions activating this band describe noticeable sensitivity to visual conditions such as light, weather brightness, or outdoor exposure, often alongside preferences for cooler, dimmer, or less visually intense settings.
High Light Sensitivity
Expressions activating this band describe clear annoyance, discomfort, or behavioral adaptation in response to bright light or sunlight, including needing sunglasses, disliking bright views, and preferring seasons or environments with less brightness.
Severe Light Sensitivity
Expressions activating this band reflect pervasive salience of bright outdoor conditions, with strong visual-environmental reactivity centered on snow glare, winter brightness, and highly brightness-laden surroundings.

Minimal Substance Use: Expressions show no meaningful substance use content. The proxy is effectively absent. Expressions activating this band are unrelated to substance use.
Emerging Substance Use: Substance use is experienced here as observable behavioral patterns associated with problematic or disordered functioning. This is the first band where substance use becomes detectable. Expressions activating this band engage with substance use at a level associated with formal behavioral assessment.
Elevated Substance Use: Substance use is experienced here as physiological and somatic distress, reflecting embodied arousal and clinical-grade symptom intensity. Unlike the band below, where substance use was characterized by the behavioral form, the proxy here has shifted in character. The facets that dominated at lower levels have receded. Expressions activating this band likely reflect physiological and embodied substance use.
Severe Substance Use: Substance use is experienced here as physiological and somatic distress, reflecting embodied arousal and clinical-grade symptom intensity. Compared to the band below, substance use is more intense and concentrated but retains the same essential character. Expressions activating this band likely reflect physiological and embodied substance use.
