To determine whether individual differences in dark focus and convergence accommodation to convergence (CA/C) ratio can be used to prescribe the best optical correction for night myopia.The best correction for night myopia was obtained by measuring v

Sixteen U.S. Army aviators, who were given training on focus adjustment technique with aviator night vision goggles (NVG), showed an improvement in visual acuity with focus adjustment compared to a fixed infinity focus control. The long-term effect o

A mathematical model is proposed for the error detector of the human visual accommodative system. The model supposes that the accommodative error detector derives both the direction and the magnitude of the accommodative error from naturally-occurrin

A special case was set up in which accommodation and vergence were totally deprived of their stimuli, in order to determine whether their responses remained coordinated or whether they became dissociated. A dynamic, infrared optometer and infrared, e

The optometrist observes and must distinguish between physiologic and pathologic changes in the cornea. This paper deals with normal, physiologic age-related corneal changes. Age-related changes are those that occur over the entire life span, not mer

Tonic aftereffects of accommodation were investigated under three open loop conditions; Maxwellian view (pin hole pupil), empty field, and darkness. Duration of accommodative aftereffects, following 5 sec of adaptation, ranged within several seconds
