How we see color

How We See Color Changes Over Time

We all know how important light is when it comes to color. In fact light is pretty much what makes color. In daylight the colors in your house look very different than they do at night with artificial lighting from lamps and such.

We also know that as we age our vision changes… so many people start needing glasses to read their morning paper and to do the things we used to do with no problem. But did you also know that the lens in our eyeballs can yellow over time as well? This yellowing causes a change in how we view the blue/violet end of the spectrum. Blues can look more gray and a bit more dull which can make it difficult to accurately depict the colors for color matching or touching up an old paint job. Red however tends to be much more vivid than before, bringing out even small amounts of reds in a pattern.

Changes in the ability to differentiate shades and tones and fine details also can decrease as we age. This has been attributed to the decrease in the number of nerve cells that are used to transmit visual signals from the eye to the brain. They are also the same nerve cells that are used to perceive and judge distance and depth… causing us to need glasses for things like reading and driving like mentioned before.

There is something however that can be done do correct all of this! Something many older people get is cataracts. The surgery to correct this also addresses the yellowing of the lens which ultimately takes the “age” of the eye back to that of an infant. The vision and color perception is clean and clear. If this surgery is something that you ultimately need… do not hesitate, it could just change the way you see things.
