Click where someone is looking and see tunnel vision or half-field loss from glaucoma on a screenshot, with how much content falls in the blind area.
Use the guide alongside the working tool.
Open Glaucoma Simulator →Pick the exam and document
Add a screen, page or sign, or try the sample.
Frame and clean up
Click where the eye is looking, then pick narrowed view, upper or lower field loss and a stage.
Create and check
See how much text falls in the affected area and export the result.
Privacy and limits
Field loss is drawn as a soft blurred mask; real loss varies and the brain fills it in, so people often do not notice it. Not a diagnosis. The image stays on your device.
