ContrastCheck

ContrastCheck is a mobile AI-assisted vision screening app focused on contrast sensitivity and glare—two everyday problems that standard “20/20” acuity tests often miss. Users run short, guided tests in controlled lighting using on-screen patterns and a calibration step (credit-card size + brightness check). The app produces a simple report: contrast score, glare sensitivity estimate, and “situational risk” flags (night driving, bright office lighting, screen fatigue). It also tracks changes over time and can export a clinician-friendly PDF. This is not a diagnostic tool; it’s a repeatable self-screen that helps people decide when to see an optometrist and what to mention. Realistically, accuracy depends on device screen quality and user compliance, so the app positions itself as trend detection and education, not medical certainty.
