CHANGES IN VISUAL DEPTH PERCEPTION WITH THE WEARING OF CONTACT LENSES

Abstract

Data for spectacles and each of 3 types of contact lenses (Obri g fluid, Obrig Lacrilens, and Dallos) at each of 6 times of measurement during a 460-min wearing period were analyzed for 8 subjects. The differential performances with the different lenses in altering the stereoptic acuities (standard deviation of 15 rangings made with a stereoptometer on a target at 3020 mm) and the spatial localization (arithmetic mean of the 15 rangings) scores were dependent upon the differences among the subjects. Spatial localization scores tended to increase with time.
