Outline of Final Research Achievements

We demonstrated that the visual function would improve followed by the increase of the brightness, and the fixation area where the central area to see the target would be changed depend on the brightness. Furthermore, we also demonstrated that the fixation area would be changed depend on the fixation target used for the examination.
This study brought us the clinically important knowledge, as it clarified the possibility that the real visual function in our daily life could not be evaluated by the conventional examination. And the clinical significance would be valuable as it clearly showed the condition of the visual function examination for the low vision care.
