Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
Ratings & Reviews
Vision Simulator is now free to download, with a one-time $1.99 Pro unlock for the full clinical toolkit.
Free: camera and photo upload, 6 realistic samples (reading test, eye chart, Amsler grid, and more), and 4 of the most common conditions — Myopia, Astigmatism, Cataract, and Normal Vision for reference.
Pro unlock ($1.99, one-time): 7 additional conditions — Glaucoma, AMD, Diabetic Retinopathy, Color Blindness, Floaters/PVD, Retinitis Pigmentosa, and Presbyopia — plus the ability to combine multiple conditions at once and side-by-side Compare mode to drag between normal vision and any simulated impairment.
Also in this update:
• Bigger, clearer app title
