Key Takeaways
- The retina is the light-sensitive tissue at the back of your eye, with the macula being the part that handles your sharp, central vision.
- Smoking is tied to a higher risk of age-related macular degeneration, or AMD.
- Vaping liquids often carry higher nicotine levels, and long-term effects of nicotine alone are still being studied.
- Early AMD often shows no noticeable signs, so routine eye exams matter.
- Quitting smoking can lower your risk of AMD and cataracts.
When you think of smoking, you might associate it with damage to the lungs or the heart. But the tissue at the back of each eye, the one you rely on to read a menu or spot a familiar face across a parking lot, can be damaged by nicotine, too. At our Eye Care Clinics, we want you to understand the risks of smoking on your vision and what you can do to stay healthy.
Nicotine use, whether through smoking or vaping, is associated with damage to the retina and a higher risk of age-related macular degeneration, and quitting can help lower that risk over time.
An Overview of the Retina
Your retina is the light-sensitive tissue at the back of your eye. Inside it is the macula, the small area responsible for your sharp, central vision. Damage to the macula can cause blurred, distorted, or lost central vision while side vision stays intact.
How Smoking and Nicotine Are Linked to Retina Damage
Smoking has been tied to a higher risk of age-related macular degeneration, or AMD. This condition damages the macula, which can lead to lost central vision over time. This is why your eye doctor may ask you about smoking during your eye exam. Knowing your risk for certain conditions can help your team know what to look for.
Many people think vaping is better for you than smoking, but that’s not true. Vaping liquids often carry higher nicotine levels than cigarettes, and the long-term effects of vaping are still being studied. Smoking and vision loss have been connected in public health research for years.
Smoke and Vapour Use Together
People who both smoke and vape report more eye discomfort than those who do one or the other. If you smoke or vape, you may notice the following symptoms in your eyes:
- Dryness or a gritty feeling
- Redness or irritation
- Blurry vision
- Light sensitivity
- Headaches
Other Eye Concerns Connected to Tobacco Use
AMD isn’t the only concern. Smoking is also associated with cataracts and dry eye, both of which can make evening driving and screen time uncomfortable.
For people with diabetes, smoking is linked to diabetic retinopathy. It’s also associated with a higher risk of thyroid eye disease. Our team can explain how these overlap with your health history.
Signs of AMD to Watch For
In most cases, early AMD has no noticeable symptoms at all. As AMD progresses, you may begin to notice some changes to your central vision, including:
- Blurry or wavy spots in the middle of your vision
- Trouble recognizing faces
- Needing more light than usual to read
If straight lines on a door frame or a page of text start to look bent, that’s worth mentioning to your eye doctor. Regular eye exams help detect these changes sooner, when there are often more treatment options available. Your eye doctor can assess your retina for signs of damage and help you determine your next steps.
How to Lower Your Risk
The most important step you can take to support your eye health is to quit smoking and keep up with routine eye exams. Eating a balanced diet, limiting second-hand smoke, and maintaining a regular exercise routine also support your overall health, including your eyes.
When to Book an Eye Exam
Any new change in your vision is a good reason to book an eye exam. If AMD runs in your family, mention it to your eye doctor, since that history shapes how often they’ll recommend you come in. If you smoke, vape, or quit years ago, that’s also worth mentioning to your eye doctor, as it helps guide the exam.
