In California, a study showed that people who engage in moderate to vigorous physical activity may significantly lower their risk of glaucoma. Researchers from the University of California, Los Angeles reported a 73 percent decline in the risk of developing the disease among the most physically active study participants, compared with those who were the least active.

Glaucoma is a leading cause of blindness in the U.S.  It has long been thought that lifestyle choices do not play a role in glaucoma, but several recent studies show that lifestyle factors can influence eye pressure, which is a major risk factor for the disease.

The researchers examined the correlation between exercise intensity and glaucoma and found that for each 10-unit increase in walking speed and number of steps taken per minute, glaucoma risk decreased by 6 percent. For each 10-minute increase in moderate-to-vigorous activity per week, glaucoma risk decreased 25 percent.
