Optokinetic nystagmus (OKN) is used to study the eye's ReAdaptation Time (RAT) after a brief exposure to a light Hash. The effects on RAT of breathing different concentrations of O 2 are examined Significant changes in RAT have been registered, showing that inhalation of 100% O 2 as compared with room air, results in a shortened RAT (i.e. improvement), while inhalation of 9% O 2 leads to an increased RAT (i. e. impairment) The physiology of RAT and the possible mechanisms behind the changes caused by different Oo concentrations are discussed. The findings ol this group are compared with those of other studies
