How does smoking influence eye health?

Smoking has a well-documented negative impact on eye health. It increases the risk of various eye diseases, including age-related macular degeneration (AMD) and cataracts, as well as other serious conditions like diabetic retinopathy and uveitis. The toxins found in cigarette smoke can lead to oxidative stress, inflammation, and vascular damage within the eye.

For instance, AMD is one of the leading causes of vision loss, particularly in older adults, and studies have shown that smokers are at a significantly higher risk of developing this condition compared to non-smokers. Similarly, cataracts, which cause clouding of the lens and ultimately impairs vision, have been shown to have a higher incidence among smokers due to the harmful chemicals in tobacco that contribute to oxidative damage in eye tissues.

By increasing the risk of these and other eye diseases, smoking can ultimately affect one's overall quality of life and visual capabilities. Therefore, it is crucial for individuals to recognize the risks associated with smoking for eye health and to consider cessation as a way to improve their overall wellbeing.
