Tobacco use, danger for the eyes

Smoking harms every organ in the body, including the eyes. The harmful - and often fatal - health effects of smoking, such as cancer, respiratory and heart disease, are relatively well known. In contrast, the damage to vision caused by smoking, with the risk of blindness, are generally less well known. For example, smokers are up to four times more likely to become blind than the general population.

Age-related macular degeneration (AMD)

Smokers and ex-smokers are more likely to get AMD than people who have never smoked.

This disease occurs when a part of the retina called the macula is damaged. It results in a progressive loss of central vision while peripheral vision remains relatively normal, which results in the inability to see details and, in particular, to read. Current treatments remain ineffective.

Uveitis

The uvea is made up of the iris, the ciliary body and the choroid. Its inflammation is called uveitis, it results in a red and painful eye. The consequences of uveitis are varied and can be serious, with the possibility, in particular, of glaucoma. Uveitis is more common in smokers

Cataracts

Similarly, tobacco consumption increases the risk of cataracts, due to opacification of the lens, with the occurrence of blurred and dull vision.

Diabetic retinopathy

Smokers who suffer from diabetes are at greater risk of developing diabetic retinopathy, due to damage to the blood vessels that supply the retina, with deterioration of vision that can lead to blindness.

Optic nerve problems

People who smoke are at risk for optic nerve problems. The optic nerve connects the eye to the brain. Damage to this nerve can lead to blindness.

Smoking can increase risk factors that can lead to glaucoma, a disease that affects the optic nerve.
