Smoking increases the risk of several serious eye diseases and can accelerate age-related changes. Stopping smoking is one of the most important steps you can take to protect your vision.
Associated Conditions
Smokers have a higher risk of age-related macular degeneration, cataract, and vascular problems that can lead to retinal vein or artery occlusions. Smoking during pregnancy is also linked to eye and vision problems in children.
- Chemicals in smoke damage blood vessels and retinal cells
- Oxidative stress contributes to earlier lens clouding
- Passive exposure may affect non-smokers in the same household
- Smoking worsens dry eye symptoms and ocular surface irritation
Benefits of Stopping
Quitting smoking reduces future risk and may slow progression of existing disease. Eye care professionals can signpost support services and emphasise the visual benefits of stopping.
- Risk of macular degeneration falls over time after quitting
- Stopping also improves cardiovascular and general health, indirectly helping the eyes
- Some procedures and treatments have better outcomes in non-smokers
- Use eye symptoms as additional motivation when planning to stop
