Glare and Night Vision Impairment in Corrective Lens Wearers

Abstract

Glare sensitivity, night vision and glare recovery measures on a night-driving vision tester were collected on 60 students, of whom 34 had uncorrected vision, 18 wore corneal contact lenses and 8 wore spectacles. An analysis of variance disclosed significant decrements in glare sensitivity and night vision for those with corrected vision. Further analysis with a pairwise comparison on contact and spectacle wearers showed hard contact lenses to be worst, followed by soft contact lenses and spectacles. A concern for the ability and safety of corrective lens wearers during nicht driving is indicated.
