Although most people are aware that smoking could damage the lungs, heart, and skin, many people may not fully recognize how smoking worsens the health of the eyes. Like the rest of the body, your eyes are exceptionally sensitive to the toxic compounds in cigarette smoke. This includes both the active smoker and the innocent bystander inhaling secondhand smoke. If this describes you, it’s time to be concerned.
This article will cover how smoking damages your eyes; the risk of long-term vision loss; and the importance of prevention before it’s too late.
How Smoking Damages Your Eyes
There are over 7,000 chemicals in cigars and cigarettes; many harmful, and can go through your bloodstream, into the delicate tissues of your eye. Damaged eyes are often slow, silent damage that is permanent. Here’s a breakdown of how smoking damages your eyes:
1. Increases the Risk of Cataracts
The lens of your eye becomes cloudy by a cataract, which is characterized by blurry, hazy or dull vision. Smoking doubles your chance of developing cataracts, and by increasing chemicals in cigarette smoke by as much as 30 could increase oxidative stress and quickly age the lens in smokers. Timing is important too, as smokers may develop cataracts before non-smokers.
2. Contributes to Age-Related Macular Degeneration (AMD)
How smoking damages your eyes becomes most evident in AMD which is a major reason for loss of vision in adults over 50. Your chances of developing AMD triple through the use of tobacco. As the disease progresses, so does damage fully or partially to your macular resulting in loss of sharp vision. This results in difficulty reading, driving or recognizing faces.
3. Worsens Dry Eye Syndrome
Smokers frequently mention having red, irritated, or itchy eyes. This is because smoke is a potent irritant and dries out and depletes the protective tear film on your eyes. A person with dry eye syndrome will notice his or her symptoms exacerbated considerably if they smoke or are exposed to secondhand smoke.
4. Increases Risk of Uveitis
Uveitis is inflammation of the uvea, the middle layer of your eye. The eye can appear red and painful, but it can also lead to visual impairment/loss. Therefore, on your worst day, smokers are more than twice as likely to develop uveitis. The condition can damage your retina and optic nerve and cause permanent visual defects.
5. Can Lead to Optic Nerve Damage
The optic nerve carries visual information from your eye to your brain. Smoking can obstruct blood and nutrient flow to the optic nerve. If left undisturbed this can lead to optic neuropathy, a serious ailment that could leave you with blind spots or total vision loss!
6. Increases the Risk of Diabetic Retinopathy
If you’re a diabetic and a smoker, the risks to your eyes multiply. Smoking causes narrowing of the blood vessels, which adds to the complications of diabetic retinopathy. Damaged blood vessels in the retina can leak fluid or bleed, leading to blurred vision and eventually blindness.
7. Higher Risk of Graves’ Eye Disease
Graves’ eye disease affects the thyroid. This can lead to bulging eyes, eye sensitivity to light, and pain. Smokers with Graves’ eye disease are much more likely to suffer from severe problems with their eyes than non-smokers. By quitting smoking, a person can mitigate some of the symptoms of Graves’ eye disease.
8. Impairs Night Vision
Tobacco smoke inhibits the release of rhodopsin in the retina. In particular, rhodopsin is a pigment that helps the eyes adapt when entering a darkened area, such as driving in the dark. Not only does smoking inhibit your ability to drive in the dark safely, but also puts you at a greater risk for a crash incident.
9. Hinders Recovery After Eye Surgery
Smokers heal slower. Whether it’s cataract surgery, LASIK, or another eye surgery, smoking affects healing times, increases your risk of developing an infection, and reduces your surgical results. This is another reason for you to quit smoking before any eye surgery.
Secondhand Smoke Is Equally Harmful
Even if you are not a smoker, being near someone smoking can jeopardize your eye health. Children and elderly individuals are also more sensitive to this. Secondhand smoke can irritate the eyes and cause other allergic and conjunctival disorders.
Signs Your Eyes May Be Affected by Smoking
- Ongoing irritation of the eyes
- Redness and dryness of the eyes
- Blurring / cloudy vision
- Difficulty seeing in the dark
- Increased sensitivity to light.
- Sudden loss of vision.
If you are experiencing these issues, it is important to seek medical advice promptly.
What happens if you quit smoking?
The good news is—quitting will help. The body will start to heal as soon as you quit smoking. Improvements in circulation occur within weeks. Months later eye tissues start to heal, and within a year, the risks associated with many smoking-related problems decrease significantly.

- Quit Smoking: The most effective step you can take. Seek support through medical help, counseling, or nicotine replacement therapy.
