Other Risk Factors

Long-term drug use, including chemotherapy and the use of corticosteroids, whether taken orally, inhaled, injected, or applied to the skin

. Heredity; a family history of early cataract development

. Dark eye color

. Gender (women, especially those who started menstruating late, being at higher risk)

. Severe myopia-although eyeglasses, worn for many years, apparently provide protection against ultraviolet radiation and can offset the risk from nearsightedness

Low cholesterol levels in the lens and cerebral cortex can contribute to cataract formation, according to a Japanese study published in 2006. The study cautioned physicians to be aware of this effect when prescribing cholesterol-lowering drugs. Paradoxically, a University of Wisconsin study (2006) and two Australian studies (2007) have shown that taking cholesterol-reducing drugs known as statins significantly slows cataract development and also reduces the risk of macular degeneration. Researchers are working to clarify the relationship between cholesterol and cataracts.

Can you prevent cataracts? Not entirely. But you might well delay the onset of cataracts by being sensible about sun exposure, wearing UV-protective sunglasses and a hat with a brim when you're outdoors, eating well, keeping fit, learning to relax, and staying upbeat in the face of stress. Delaying cataract formation is just one of many reasons to cultivate a lifestyle that promotes health and well-being.
