A device and method for providing a stimulus to the measurement of the field of vision of the human eye. The stimulus is presented at predetermined test sites in a region of the background of a perimeter to a person to be tested. The stimulus has at least two visual characteristics that ...
A number of test locations determined by co-ordinates are fixed in the field of vision so that at least one further test location is present around each test location. Each test location is subjected to only one stimulus. An original initial value is fixed for each test location for the st...
