Eye Diseases Linked to Smoking
Smokers are twice as likely to develop cataracts, a condition where the eye’s lens becomes cloudy and vision is impaired.
Age-Related Macular Degeneration (AMD)
Smoking is the leading modifiable risk factor for AMD, a disease that damages the central part of the retina, leading to loss of detailed vision.
Dry Eye Syndrome
Tobacco smoke irritates the eyes and contributes to dry eye symptoms, leaving the eyes feeling gritty, red, and uncomfortable.
Optic Neuropathy
Smoking increases the risk of optic nerve damage, leading to permanent vision loss in severe cases.
