Vuscope - Visual Field Screener
Measure the display width of your computer screen
and perform the test at 1.5 times this distance
from the screen.
Wear reading glasses if you normally wear them
Decide on which eye you are going to test,
and when you are ready, choose one of the buttons
below to start the test.
Have a comfortable means of covering the other eye.
Make sure there are no reflections on the computer screen.
N.B. If you just about see a spot, it counts as seeing it.
