Cataract Linked to Smoking

Posted on March 12, 2008 in Latest News

Cataracts can develop due to smoking. The risk of cataract formation is higher if the duration of smoking is longer. Studies highlighted in the Journal of the American Medical Association clearly indicate that non-smokers are at a less risk of cataract formation as compared to smokers. Even if they give up smoking, the risk can remain. Dr. June M. Weintraub at the Harvard Medical School in Boston has also observed the link between cataract formation and smoking. Let us observe this further.

How Cataract is Linked to Smoking?

• Smoke gets into the eye and causes cataract
• Smokers are at risk of developing cataracts and heavy smokers are at a greater risk
• Those who smoke for less duration expose the eyes much less to exhaled smoke
• It has not been clearly established whether quitting smoking helps to reduce cataract formation
• The clouding of the eye due to cataract can lead to vision impairment and vision loss
• Tobacco smoke affects the eye directly and damages the lens protein as well as the fiber membrane cell in the lens
• Damage caused on account of cataract formation due to smoking heals very slowly

Smoking per se is bad for health and if it can affect the eye, one should avoid smoking. Cataracts can cause blindness, and smoking, being a risk for cataract formation, can indirectly cause it. Smoke from the cigarettes is bad for the eyes.
