Tobacco and Vision: The Overlooked Link
Tobacco and Vision: The Overlooked Link
By: Graham R. Stetson, OD, MS
Most people connect smoking with heart and lung disease, but tobacco also plays a role in eye comfort and long-term vision. The same chemicals, especially nicotine, that affect blood vessels and increase inflammation in the body also affect the vessels and the delicate tissues of the eyes. The symptoms are not always immediate, which is why they can be easy to overlook.
A common issue for smokers is dry, irritated eyes. Smoke irritates the surface of the eye and makes tears evaporate faster, leading to burning, stinging, redness, or a gritty feeling. Screen time, cold weather, and heated/air-conditioned room can make symptoms worse. Even secondhand smoke causes similar irritation, particularly for children and older adults.
Over time, tobacco use is also linked with a higher chance of certain eye conditions that can affect vision. Smoking increases the risk and severity of age-related macular degeneration (AMD), a condition that impacts central vision and can lead to significant vision loss as it advances. Nicotine and other chemicals in tobacco products accelerate the growth of cataracts, which cloud the eye’s natural lens and leads to glare and blurry vision. Tobacco use is also an important risk factor in the severity of thyroid eye disease, which causes irritation, double vision, and vision loss.
Because tobacco affects circulation, it will also make some health-related eye problems more likely—especially for people who already have risk factors such as diabetes, hypertension, and other systemic diseases. Smoking has also been connected to uveitis, inflammation inside the eye that can cause permanent damage if untreated.
The encouraging part is that quitting can help. After stopping tobacco, the body begins to recover in ways that support healthier blood flow and lower inflammation, and some risks can decrease over time. Annual comprehensive eye exams are extremely important to monitor the effects of tobacco use. See your eye doctor sooner if you notice vision loss, symptoms of dry eye, blurry or distorted vision, eye pain, flashes of light, or a sudden increase in floaters.
Quitting can be difficult for many, but it is one of the best changes you can make for your health and quality of life. Fortunately, there are many great resources for people who would like to quit. Talk to your PCP or eye doctor for information, visit SmokeFree.gov, call 800-QUIT-NOW, or check out the Quit Now mobile app.
