About this app

Vision Simulator lets you see the world the way someone with a vision condition does. Built by an optometrist as a patient-education tool, it applies clinically-informed visual effects to your live camera or any photo. Point your camera at a room, a face, or an eye chart — then switch between conditions to understand how each one changes what a person sees. CONDITIONS SIMULATED • Myopia (nearsightedness) with Snellen acuity presets • Astigmatism with adjustable axis • Cataract — yellowing, glare, and contrast loss • Glaucoma — peripheral field loss by stage • Age-Related Macular Degeneration with metamorphopsia • Diabetic Retinopathy • Color Vision Deficiency (red, green, and blue types) • Floaters & Posterior Vitreous Detachment FEATURES • Live camera or upload your own image • Side-by-side Compare — drag to wipe between normal and impaired vision • Adjustable severity sliders for every condition • Built-in sample scenes: eye chart, Amsler grid, night street, color garden • Snapshot to save what you see • Plain-language clinical notes for each condition • Works offline · No ads · No data collected A powerful way for eye care professionals to explain conditions to patients and families, for students to learn, and for anyone curious about how vision changes. IMPORTANT: Vision Simulator is for educational demonstration only. It is not a diagnostic tool and is not a substitute for a professional eye examination. All images are processed on your device and are never stored or shared.
