Testing contrast and twilight vision

A contrast or twilight vision test is often carried out as part of ophthalmological driving licence assessments. We test the recognition of visual signs in a dark environment. First without glare, then with glare. Depending on the driving licence category, the German Ophthalmological Society has certain requirements for contrast and twilight vision. We can document these precisely. Clouding of the cornea or lens, diseases of the optic nerve or retina as well as uncorrected defective vision can cause a disturbance in contrast and twilight vision. For this reason, the eyes are always examined in detail for existing diseases during an assessment.
