According to the US National Institutes of Health, smoking is a serous threat to your eyesight as you age, and can contribute to several conditions that may lead to vision loss and blindness. Eye problems usually attributed to getting older like cataracts and age-related macular degeneration can be worsened or accelerated by smoking cigarettes. Smoking boosts your risk of damage to the optic nerve, which also threatens your vision.

A cigarette habit early in life can still threaten your vision at an older age, according to the American Academy of Ophthalmology (AOO), and the risk of future vision loss increases with the amount smoked.
Hope for those who quit: While avoiding smoking altogether is one of the best ways to protect your eyesight for the future, the AOO reports that your risk of cataracts and age-related macular degeneration can diminish almost to that of people who've never smoked once you quit. Take their advice to preserve your eyesight in later life, and do what you can to stop smoking today. You'll find a wealth of information on how to do it on our smoking cessation guide site.
