Claim 0:
1. A method of measuring a quality of view over a visual field of view of an eye, the method comprising, during a measuring period:
displaying a stimulus to be followed in a stimulus position in a direction of view relative to an eye,
moving the stimulus to be followed in a field of view of the eye in varying directions and registering the stimulus positions over time,
detecting and registering gaze positions in directions of view of the eye following said stimulus to be followed over time,
determining and registering deviations between the gaze positions and associated ones of the stimulus positions where the stimulus to be followed was displayed when the gaze position was detected and magnitudes of the registered deviations, and
determining a visual field map of field portions, wherein, for each of said field portions, quality of view is determined in accordance with quality of view estimates of associated ones of the registered deviations of which the associated stimulus positions are located relative to the gaze position so that the associated stimulus positions are in that field portion, and, for each of said associated ones of the registered deviations, the quality of view is estimated in accordance with the magnitude of that associated one of the registered deviations and with magnitudes of at least preceding or succeeding ones of the registered deviations.
