title: The effect of reduced viewing time on colour vision in normal subjects and those with abnormal ocular conditions.
abstract: The effect of restricting viewing time to 3.75 ms in normal subjects is to produce a tritan-like colour response on the City University colour vision test. This response pattern is consistent and is repeatable for standard illuminant C at 600 lx. Supplementary tests suggest that the effect is due to a defect of the blue/yellow opponent system rather than a true tritan defect. The same test when repeated on subjects with amblyopia or retinal pathology provides different results which may aid in the differential diagnosis of some visual disorders.
