How to use Low Vision Simulator
- Add a screenshot, slide or poster, or try the sample.
- Pick reduced sharpness, low contrast or both, and an eye-chart level from 20/40 to 20/200.
- Read the results for detail and contrast kept, and export a side-by-side comparison.
What are the limits of Low Vision Simulator?
An approximation for design reviews based on blur and contrast loss, not a medical simulation. Real low vision varies widely. The image stays on your device.
