- <p>Two studies show a powerful link between cigarettes and
- cataracts
- </p>
- <p> Cataracts are by far the world's leading cause of blindness,
- causing visual impairment in more than 3 million people in the
- U.S. and 50 million globally. Americans alone undergo about a
- million operations a year to have clouded lenses removed from
- their eyes. A pair of major studies in J.A.M.A. (Journal of the
- American Medical Association) has now concluded that 20% of
- those cases may be caused by an activity already implicated in
- cancer, stroke and heart disease: cigarette smoking.
- </p>
- <p> Earlier studies hinted that cataracts are associated with
- smoking, along with other factors, including exposure to
- ultraviolet light and the use of steroids and alcohol. But this
- is the strongest evidence yet. Researchers monitored nearly
- 18,000 male physicians and more than 50,000 female nurses for
- five and eight years respectively, asking about smoking behavior
- and checking the incidence of cataract surgery. The conclusion:
- men who smoked more than a pack a day ran twice the risk of
- nonsmokers for developing lenses cloudy enough to require their
- removal; women who so indulged had a 60% greater risk than their
- abstemious counterparts. Both men and women lowered their chance
- of developing cataracts if they stopped smoking--but still got
- them more often than those who never smoked.
- </p>
- <p> The actual mechanism by which smoking induces cataracts is
- still unclear. One theory argues that blood is starved of
- important nutrients. But that's just a guess; more certain is
- that there is now yet another good reason not to smoke.
