Purpose Many people experience unilateral degraded vision, usually owing to a developmental or age-related disorder. There are unresolved questions regarding the extent which such visual deficits impact on sensorimotor performance; an important issue as limitations can constrain quality of life by restricting ‘activities daily living’. Examination relationship between deficit and performance is essential for determining functional implications ophthalmic conditions. This study attempts explore effect unilaterally vision performance. Methods In Experiment 1 we simulated in 30 participants using bilateral Bangerter filters whether motor was affected water pouring, peg placing, aiming tasks. 2 (n = 74) tested hypothesis that kinematic measures associated with visuomotor measuring small sensitivity decrements created monocular viewing interactions targets presented planar surface aiming, tracking steering Results 1, caused decreased task performance—confirming (and bilateral) loss has implications. 2, were two three tasks requiring rapid online feedback (aiming steering). Conclusions Unilateral measurable The benefits binocular may be particularly some groups (e.g. older adults) where inability complete necessitate assisted living. urgent need develop rigorous approaches quantification treatments conditions enable informed decisions around treatment.
