Color, Contrast and Cone Cells

One thing I am very good at, that in fact I am quite known for among my friends and neighbors, (and yet I must give all the credit to the Creator) is growing hydrangeas. These purple hydrangeas grow in our backyard and can be seen by golfers and walkers who use the golf cart path that lies behind our house.

If I am outside when someone comes along on the path when the hydrangeas are in full bloom, I am always asked, "What is your secret to growing these colorful hydrangeas?" Truly, they must be in just the right spot, because they thrive on neglect and yet reward me every summer with blossoms the size of volley balls.

Color and Cone Cells

Did you know that the macula, the center of the retina responsible for our straight ahead vision, is also responsible for our ability to see colors? Thanks to a heavy concentration of cone cells, colors are vivid and bright.

However, one of the symptoms of macular degeneration is that colors appear faded and less brilliant. This is the result of the cone cells becoming less functional or less abundant. Not only does one find that colors appear more dull, it is also more difficult to distinguish colors such as black from navy blue.

You may be surprised to find out that sunglasses with the right lens tint can actually help with contrast and the ability to distinguish colors more easily. Ever hear of sportsman such as golfers or pistol shooters who wear specially tinted glasses to help them see their target better?
