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. ## Key features - Simulates multiple vision conditions - Uses live camera or uploaded photos - Adjustable severity sliders - Side-by-side comparison mode - Built-in sample scenes - Offline functionality ## Frequently asked questions about Vision Simulator by Dr. Evans ### What vision conditions can Vision Simulator simulate? Vision Simulator can simulate myopia (nearsightedness), astigmatism, cataracts, glaucoma, age-related macular degeneration, diabetic retinopathy, color vision deficiency, and floaters. It allows for adjustable severity for each condition. ### How does Vision Simulator work? The app applies clinically-informed visual effects to your live camera feed or any uploaded photo. You can then switch between different conditions to see how they alter visual perception. ### Is Vision Simulator a diagnostic tool? No, Vision Simulator is strictly for educational demonstration purposes. It is not a diagnostic tool and should not be used as a substitute for a professional eye examination. ### Does Vision Simulator collect or store user data? No, all images are processed directly on your device. The app explicitly states that no data is collected or shared, ensuring user privacy. ### Can I compare normal vision with impaired vision in Vision Simulator? Yes, the app features a side-by-side Compare mode. This allows you to drag a wipe across the screen to compare normal vision with the simulated impaired vision. ### Does Vision Simulator work offline? Yes, Vision Simulator is designed to work offline, meaning you do not need an internet connection to use its features for simulating vision conditions. ### What is the price of Vision Simulator? Vision Simulator is a paid application, priced at $1.99. This one-time purchase grants access to all its simulation features. ### How often is Vision Simulator updated? The latest version, 2.0.1, was released on June 18, 2026, indicating recent development activity. Updates typically refine existing features and potentially add new simulations. ## Version history (last 5 releases) ### 4.0 — 2026-08-08 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 • Streamlined camera controls — fewer taps to get started • Browse all 11 conditions faster with a redesigned two-row selector • General polish and bug fixes ### 2.0.1 — 2026-06-18 bug fixes ### 2.1 — 2026-06-03 Added haptic feedback ### 2.01 — 2026-05-31 Added improved screenshots ### 2.0 — 2026-05-30 Version 2.0 brings major simulation improvements and two new conditions. New Conditions • Retinitis Pigmentosa — progressive rod loss with tunnel vision and bone spicule deposits • Presbyopia — age-related near focus loss Improved Simulations • Cataract — rebuilt with realistic light scatter and glare that blooms off bright sources; progressive darkening to a near-opaque brown haze at severe stages • AMD — Mild/Moderate/Advanced/End Stage presets; central scotoma opacity now scales with severity; metamorphopsia (wavy distortion) now correctly confined to the central vision area only • Glaucoma — Mild/Moderate/Severe/End Stage labeling • Color Blindness — fixed simulation for all three types (Protan, Deutan, Tritan) New Sample Images • Real photographs for Night Street, Color Garden, and Portrait UX Improvements • Selecting a condition now collapses the condition list so severity controls are immediately visible • Larger, easier-to-drag sliders • Share or save snapshots directly from the app ## More apps by Ryan Evans - [Dr. Glass](https://appshunter.io/ios/app/dr-glass/id6772578352) - [TapBTC](https://appshunter.io/ios/app/tapbtc/id6774023419) - [Eye Chart Test by Dr. Evans](https://appshunter.io/ios/app/eye-chart-test-by-dr-evans/id6778295355) All apps by Ryan Evans: https://appshunter.io/developer/6772578354 ## Related topics [glaucoma vision simulation](https://appshunter.io/ios/topics/glaucoma-vision-simulation) · [my eyes vision simulator](https://appshunter.io/ios/topics/my-eyes-vision-simulator) · [vision simulator](https://appshunter.io/ios/topics/vision-simulator) · [vision simulation](https://appshunter.io/ios/topics/vision-simulation) · [chromatic vision simulator](https://appshunter.io/ios/topics/chromatic-vision-simulator) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
