Vision Simulator by Dr. Evans

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

• 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.
