See a screenshot or slide with short sight, reading-age blur or astigmatism at mild to strong levels, and check that text survives.
Use the guide alongside the working tool.
Open Refractive Error Simulator →Pick the exam and document
Add a screenshot, slide or menu, or try the sample.
Frame and clean up
Choose short sight, reading-age blur or astigmatism (with its axis) and a strength.
Create and check
Check how much fine detail is kept and export the comparison.
Privacy and limits
Defocus is approximated with blur; the real effect depends on distance and pupil size. Not an eye test. The image stays on your device.
