Abstract
IT has been shown1 that the luminance necessary to produce intense visual discomfort or aversion is greater in monocular than in binocular viewing. Essentially similar results were obtained both in subjects with normal pupils and in subjects with pupils dilated by drugs. This finding indicates that pupillary and ciliary muscle spasms are not the sole causes of this effect.
