Keep An Eye On Your Sight When Driving At Night



When nights grow longer, and our morning and evening commute is spent driving in the dark, seeing the road clearly is a much more difficult task.

Driving With Visual Distraction Is Dangerous!

Unfortunately, many people don’t take this fact as seriously as they should. Perhaps they’ve become so accustomed to this type of blurred, haloed vision that they don’t notice it anymore. They simply squint and continue on their way.

Our night vision (especially when driving) can be impaired not only by the darkness, but also by the sudden glares of light from other cars, traffic signals, street lamps, etc. These things force our eyes to constantly adjust, leaving split seconds of impaired vision between adjustments.

Here’s a short video about this topic from Bausch+Lomb and The Canadian Association of Optometrists:

As We Age, This Problem Is More Pronounced

Our eyes sense light with two different types of cells—rods and cones. Rod cells work best in low light. If you’re over 40, this may be more of a problem than it used to be. Here are three reasons why:

  1. We have fewer rod cells, which work to pick up small amounts of light.
  2. The lenses in our eyes become stiffer and cloudier.
  3. The light receptors on our rods can’t regenerate as fast.
