Prevention is particularly key to consider when it comes to cataracts, a common cause of age-related vision loss. Wearing sunglasses and a hat outdoors can help shield the eyes from UV rays and avoid cataract formation later in life. Yet perhaps the most important thing a person can do with regard to cataract prevention is quit smoking.

What Are Cataracts?

Cataracts refer to the clouding of the naturally clear lens of the eye. When cataracts occur, the lens clouds over. This lead to blurry or hazy vision. When the lens is completely clouded over, it causes serious vision loss.

What Causes Cataracts?

Cataracts may form naturally as part of the aging process or as a result of injury to the eye, but their likelihood of forming increases if a person smokes.

A routine cataract removal surgery can help address the problem, but prevention is always ideal. In fact, if you do not smoke and are rarely exposed to second-hand smoke, you are far less likely to develop cataracts as a result of the natural aging process.

How Much More Likely Are Smokers to Develop Cataracts?

Far more likely.

Regular smokers are twice as likely to develop cataracts as non-smokers. Heavy smokers are three times more likely to develop cataracts than non-smokers.

Given the significant increase in risk, the link between cataracts and smoking simply cannot be ignored.

Other Eye Conditions Linked to Smoking

In addition to cataracts, smoking has been linked to a number of other vision problems and eye diseased. This includes the following:

  • Macular degeneration
  • Diabetic retinopathy
  • Dry eye syndrome
  • Uveitis
  • Lazy eye (in children of pregnant women who smoke)
  • Conjunctivitis (pink eye)
  • Optic nerve damage

If I Quit Now, Does My Cataract Risk Decrease?

Yes.

By quitting smoking, you can reduce your risk of developing cataracts in the future. A Swedish study of middle-aged men who quit smoking found that at the time they smoked, they experienced a 42% increased risk of developing cataracts. Men who quit smoking were able to reduce their increased risk of cataracts to 21% over the course of 20 years.

In other words, smokers will still experience an increased risk of developing cataracts, but the risks will not be quite as high if they quit sooner rather than later.

Quitting smoking can be easier said than done. Many people have tried to quit but have run into difficulties given how addictive nicotine can be. Thankfully there are many resources available to help make quitting a reality.
