Tinted hydrogel lenses: an assessment of glare sensitivity reduction.
The effect of tinted flexible contact lenses on light sensitivity and photophobic response has often been questioned but never thoroughly investigated. An Alpascope was used to investigate whether tinted hydrogel contact lenses would relieve glare sensitivity in pre-adapted contact lens wearers. Various densities of sky blue and autumn amber Cibasoft hydrogel lenses were used in the study. Analysis of the Alpascope data using the t-test, one-way analysis of variance and Duncan's test showed that there was no reduction in glare sensitivity when tinted contact lenses were worn.
