Outcome Measures

Primary Outcomes (2)

Perceptual Phase
The perceptual phase when the interocular contrast between the two eyes is 1.
Each subject undergoes a one-time examination, which lasts for about a year. Each subject's participation in this clinical study will take approximately 0.5 hour.
Ocular Dominance Index (ODI)
The ratio of the total time spent by the observer reporting complete dominance of visual stimuli presented to the dominant or non-dominant eye.
Each subject undergoes a one-time examination, which lasts for about a year. Each subject's participation in this clinical study will take approximately 0.5 hour.
