Colors

As we age most of us expect our vision to worsen. We expect to wear glasses and to eventually have cataracts that require surgical removal. Some unfortunate individuals have eye diseases that greatly impair vision, such as macular degeneration. One thing that might blindside (sorry, I couldn’t resist the pun) seniors is color-blindness more accurately called color vision deficiency.

Researchers from The Smith-Kettlewell Eye Research Institute administered color vision tests to several hundred adults ages 58 to 102 and found that 40 percent had abnormal results. The rate was significantly higher in those over 70 and rises with age after seventy. The type of color vision abnormality is different from inherited color-blindness which usually involves red and green.

I first realized I had this problem a couple of years ago. In my experience purple almost always looks brown. Often pink looks yellow. The amount and type of light greatly affect how I perceive these and other colors. Purple inside looks brown, but moving it into the sunlight sometimes reveals the true color.

If you have this problem you probably are already aware, but there are simple tests available Online. A word of caution, some sites charge a fee and others may result in unwanted email followup.
