Your vision at night is different, and sometimes not quite as sharp as it is during the day. When the natural daylight is eliminated you not longer have comparative vision. That means you can't judge distances as well because you can't see for example, the crosswalk in relation to the tree on the corner. These peripheral items help you to judge distance and depth. Glare is also a factor when driving at night. A digital anti reflective coating is in fact a filter that allows all the light to pass through the lens eliminating all the glare and refections from traffic and street lights.
