Abstract

Volume 33, Number 2, April 2008 As people age their color perception changes, in particular as cataracts develop. The changes are in terms of three factors: color, brightness, and haze. The color change, due to the changes of the transmittance of the crystalline lens in particular in the blue region, and brightness changes, due to the an overall decrease in transmittance, have been studied widely. But generally the changes resulting from haze have not been explored in such depth. Mitsuo Ikeda and Tomoko Obama report on a study of the effects of haze on the color perception in ‘‘Desaturation of Color by Environment Light in Cataract Eyes.’’ As the title suggests, they confirmed that environmental light which is generally white, gets scattered through the lens of cataract eyes, (or when wearing goggles to simulate cataracts) producing a white haze that generally makes colors appear less saturated as compared with the perception of normal younger observers. This was confirmed by both young observers wearing special goggles, and by comparisons of vision with an elderly observer before and after cataract surgery. Thus the effects of environmental light should not be overlooked when studying the vision of those people with cataracts.
