Can Smoking Cause Cataracts?
Can Smoking Cause Cataracts

The impact of smoking on health is widely discussed, but what about its effects on eye health, particularly the development of cataracts? Let’s explore this topic in detail.

The Basics: What are Cataracts?

Cataracts occur when the lens in the eye becomes cloudy, leading to a decrease in vision. While ageing is the most common cause, other factors can contribute to the formation of cataracts.

The Link Between Smoking and Cataracts

Smoking introduces a host of harmful chemicals into the body. These chemicals can cause oxidative stress, a process that damages the eye’s lens. Several studies have found a strong link between smoking and an increased risk of cataracts.

How Much Does Smoking Increase the Risk?

The risk of developing cataracts increases with the number of cigarettes smoked over time. Even passive smoking (second-hand smoke) can elevate the risk slightly.

What Happens if You Quit?

Quitting smoking can reduce the risk of developing cataracts, but it’s important to note that it does not reverse the effects of any cataracts that have already formed. While quitting may slow the progression of cataracts and offer numerous other health benefits, it won’t eliminate the cataracts that are already present.

Consult Your Eye Doctor (Ophthalmologist)

If you smoke and are concerned about the health of your eyes, it’s crucial to have a comprehensive eye examination by an ophthalmologist. They can assess the condition of your eyes and provide personalised advice.
