[Glare test and bright light vision in cataract patients]

Cataract patients and healthy subjects have been examined with the Miller-Nadler Glare-Tester to prove if the results of the glare test show any correlation between the glare disability score and the outdoor visual acuity facing sun. The outdoor vision of cataract patients with a high glare disability score was clearly impaired compared with their indoor vision. Healthy eyes with a normal glare disability score did not show any impairment of visual acuity facing sun. The results of the glare disability examination can therefore be used as a reference for the decision of a cataract operation.
