Still, the findings raise issues about whether assumptions about the lack of problems are true. "There's another question: What in the visual system is causing these changes?"

Michael Crognale, director of cognitive and brain science with the department of psychology at the University of Nevada, Reno, cautioned that changes in color vision can be a sign of significant medical problems, such as diabetes.

This is different from inherited colorblindness, which is more common among men and prevents people from distinguishing red from green.

In the new study, researchers sought to understand how common the color vision problems are among older people. They gave tests to nearly 900 people aged 58 to 102 from the Northern California enclave of Marin County, leaving out anyone who had inherited colorblindness.

A new study finds that many people lose their ability to clearly distinguish certain colors as they age, with losses typically starting around age 70 and getting worse over time.

But there's good news too: In general, the loss of color vision in seniors doesn't seem to affect day to day life.

Researchers have long known that color vision can deteriorate as people get older, Schneck said. The lenses of their eyes can become yellowish, causing them to see as if they were looking through a yellow filter, she said. This can disrupt their so called "blue yellow" vision, preventing them in certain situations from distinguishing blue from purple and yellow from green and yellow green. Problems are especially apparent when colors are washed out, Schneck said.

As for preventing loss of color vision due to aging, forget it. That's the word from Stephen Dain, who studies color vision as a professor with the School of Optometry and Vision Science at the University of New South Wales, in Sydney, Australia. Deterioration of color vision is "as inevitable as death and taxes," he said.

Color vision problems in the blue yellow spectrum affected 45 percent of people in their mid 70s, and that proportion rose to two thirds by the time people reached their mid 90s. Few people had problems with the red green spectrum.

As for causes, Schneck said they appear to be cataracts, retinal disease and normal aging, although she said more research is needed to better pinpoint what's going on.
