A recent study published on the seniordriving.aaa.com website, claims that when a person hits 60, they will need three times as much light as when they were twenty years-old to detect the same obstacles. Therefore, as we get older, it becomes harder to properly detect objects in the dark, which is an even greater concern if you are behind the wheel at night.
Research has shown that our pupils shrink, but fail to adequately dilate as conditions darken, adversely affecting night vision. Our eyes become unable to cope with glare, and are therefore less capable of seeing reflective signage, even more so when other visual disorders are present. The website also features a tool that simulates the different degrees of night-vision performance at 20, 40, 60, and 80 years of age.
