The choices that people make about how they want to live their lives can have an impact on their vision. With this in mind, many individuals want to exercise more, drink less, and smoke not at all. A recent study involving 5,000 adults reveals that “visual impairment” (sight loss caused by eye disease, injury, or a medical condition that cannot be corrected by glasses or contact lenses) is more prevalent among inactive individuals, heavy drinkers, and smokers. After adjusting for age, regular exercisers were 58% less likely to develop vision problems than sedentary types. Occasional drinkers were 49% less likely to develop eye problems than nondrinkers, and heavy smokers were somewhat more likely than nonsmokers to develop visual impairment. You can’t always determine when your vision is slipping. By the time you can, you may have wasted valuable time in helping your eyes get back to better health. Poor vision is not just a function of your age – and it does not have to be inevitable. The number of Americans with visual impairment is expected to grow to at least four million by 2020, which represents a 70 percent increase from 2000.
