1. Introduction. Glare is the visual effect of scattering light within (or in front of) the eye caused by a relatively bright light source in the field of view (Miller & Benedek, ; Van den Berg et al., ).The scattered light (veiling) reduces retinal contrast across the visual field and thus reduces overall visibility (disability glare), in addition to causing distraction and annoyance Cited by:.
