Purpose: Measurement of glare and straylight may give important information about the visual capacity of elderly drivers and drivers with cataract. However, the measurement technique must be adequate. Current techniques have been insufficiently investigated on this issue. We evaluated several test devices: the Nyktotest and Mesotest (both for measurement of glare), the Straylight meter, as well as a new computer implemented Straylight meter.
Method: We studied: 1) Young subjects without eye disease; 2) Elderly subjects without eye disease and 3) Subjects with (early) cataract in at least one eye. Each group included about 40 subjects. We measured glare, straylight, as well as visual acuity, contrast sensitivity, eye colour and LOCS III cataract. Subjects filled up a questionnaire into perceive disability during driving.
Results: The repeatability, validity (in relation to LOCS III
