The Effects Of Driving At Night

Here we explain some of the effects of night driving on your vision.

The Blur Effect

The so-called blur effect is when what you see in the dark becomes blurred. This happens because when the light levels are reduced, the pupil in the middle of the eye open up in size to admit more light. This can cause what you see to become de-focussed or blurred.

Glare

Glare from automobile lights, particularly from the rear view mirror can lead to temporary loss of vision.

Change Of Light Intensity

It is well known that our eyes take time to adjust to new levels of light, whether going from a dark place to a bright place or vice versa. While our eyes take this time to adjust there is a temporary impairment to our vision.

Moving from bright areas (high levels of road lighting such as large motorway intersections) to dark areas, end of the intersection in rural areas where there are minimal road lights occurs frequently on any long night journey. The driver suffers, not just temporary vision impairment, but over a long journey the effect can add to fatigue.
