Abstract
A preliminary report on a research project on night vision, glare vision and glare recovery utilizing an automatic device is presented. Data indicate that night vision scores cannot be used to predict glare sensitivity scores and vice versa, that nyctometer test scores deteriorate with increasing age and that glare recovery scores are related to sex. Further, there is a connection between accident and conviction history and nyctometer test scores. Many examinees overestimated their night vision and glare recovery.
