Warning: This app is a simplified version of a formal visual field test and cannot replace a professional eye examination.
It is designed for individuals with progressive eye diseases to simply check for changes in their visual field at home.
Please perform the test in the same environment each time. Use on a mobile device is not recommended.
Keep looking at the black point and cross in the center.
If you see the red dot, immediately press the 'Click!' button at the bottom of the screen.
More points lead to higher accuracy.
Please select the point size and number of points.
