When we think of the health effects of smoking, the lungs and heart often come to mind. However, the eyes, these delicate organs that are essential to our daily lives, also suffer significant damage from smoking.
Increased risk of serious diseases
• Age-related macular degeneration (AMD): Smokers are up to four times more likely to develop AMD, a disease that can lead to progressive loss of central vision. The toxic substances in cigarette smoke increase oxidative stress and damage retinal cells.
• Cataracts: Cigarette smoke contributes to the formation of cataracts by increasing the accumulation of free radicals in the crystalline lens, leading to its opacification. Smokers have a higher risk of developing this condition.
• Optic neuropathy: Smoking reduces the oxygen supply to the optic nerves, which can lead to irreversible vision loss.
Effects on the surface of the eye
• Dry eyes: Cigarette smoke irritates the eyes and reduces the quality of tears, causing burning, itching and discomfort. This problem is particularly annoying for contact lens wearers.
• Conjunctivitis: Smoke toxins can also increase the risk of inflammation, such as conjunctivitis.
Increased risk for babies and children
• Passive smoking can have serious consequences for children's vision, including an increased risk of strabismus and amblyopia (lazy eye). In addition, exposure to smoke during pregnancy can affect the development of the fetus' eyes.
A vicious circle of damage
The chemicals contained in cigarettes, such as carbon monoxide and nicotine, disrupt blood circulation. This limits the supply of essential nutrients and oxygen to the eyes while encouraging the accumulation of toxins in eye tissue.
How can you protect your eyes?
• Stop smoking: This is the best decision you can make for your eyes and general health. The risk of eye disease begins to fall shortly after you stop.
• Protect those around you: Avoid smoking in enclosed spaces to reduce exposure to passive smoking.
• Consult an Optometrist regularly: An eye examination can detect smoking-related diseases at an early stage.
Smoking doesn't just damage your lungs; it also puts your vision at risk. By adopting a smoke-free lifestyle, you're preserving your eyes and quality of life. Remember: your eyes deserve as much care as the rest of your body.
