The effect of smoking on vision

Smoking has been confirmed to be related to the following eye diseases and may even exacerbate the severity of the disease:

Heavy smoking (15 cigarettes per day) Or above) three times the risk of developing cataracts than non-smokers.

Age-related macular degeneration (AMD)

Studies have confirmed that smokers are three to four times more likely to develop AMD than non-smokers. Specifically, both smokers and former smokers are at higher risk. Non-smokers who live with smokers may also develop AMD. The risk doubled. Age-related macular degeneration (AMD) mainly affects the macula. The macula is the center of the retina. The disease can cause blind spots and severely impair central vision. Losing the health of this part will cause you to lose the sharpness of the visual field, the central visual field, and the fine details of the observation. ability. In a study, AMD is one of the leading causes of permanent blindness in Americans 65 and older.

Smokers with diabetes increase the risk of diabetic retinopathy, which damages the blood vessels in the retina, causing blurred or distorted vision, and more likely to cause vision loss.

Iris

Iriditis is an inflammation of the middle layer of the eye or the uvea. It can also damage other important parts of the eye, such as the iris and retina. This is a serious eye disease, which may lead to various complications such as cataracts, glaucoma, and even total blindness.

Studies have shown that smokers are 2.2 times more likely to suffer from uveitis than non-smokers. Smoking has a clear relationship with the occurrence of uveitis.

Infant eye disease

Smoking is not only harmful to adult smokers, but also harmful to women who smoke during pregnancy and their upcoming babies. Smoking causes dangerous toxins to spread to the placenta and may harm unborn children. This increases the chance of the fetus/baby suffering from eye diseases, not to mention other serious health problems that smoking may cause.
