Glare can come from sources in front of or behind a vehicle. Most attention has been paid to the problem of glare from oncoming vehicles. Yet glare from following vehicles can be just as severe, and continue for longer periods of time. This paper examines the problem of glare from the rear view mirrors, both from a point of view of its effect on visibility and discomfort. It is shown that such effects can be quite significant. Methods of reducing the glare levels are discussed.
