smoking tobacco (cigarettes, cigars or pipes) can cause lung disease, heart disease, cancer, and many other serious health problems. But did you know that smoking can also harm your eyes?

Here are some eye problems that are made worse by smoking:

1. Dry eye

This is when your eyes do not have enough—or the right kind of—tears. Smoking with dry eyes will make your eyes more likely to feel scratchy, sting, burn or red.

2. Cataracts

If you smoke, you are at increased risk of getting cataracts. A cataract is a clouding of your eye’s naturally clear lens. It causes blurry vision and makes colours look dull, faded or yellowish. Cataracts are removed with surgery.

3. Age-related macular degeneration (AMD)

This disease happens when a part of the retina called the macula is damaged. You lose your central vision and cannot see fine details. But your peripheral (side) vision stays normal. Sometimes medicine or laser can help certain people with AMD from getting worse. But there is no cure. Studies show that smokers and ex-smokers are more likely to get AMD than people who never smoked.

4. Diabetic retinopathy

Smokers who also have diabetes risk getting diabetic retinopathy. Diabetic retinopathy is when blood vessels in the eye are damaged. It causes blurry or distorted vision and possibly blindness. Treatment includes medication( injection of drugs into the vitreous cavity), laser or surgery.

5. Optic nerve problems

People who smoke risk having 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 which can lead to glaucoma—a disease that affects the optic nerve.

6. Uveitis

Smoking can lead to a disease that affects part of the eye called the uvea. This is the middle layer of the eye wall. Uveitis is when this layer becomes inflamed (red and swollen). This disease causes red eye, pain and vision problems.

7. Graves’ disease

This is a disease of the body’s thyroid gland where there is excessive secretion of the. One of the symptoms of Graves’ disease is bulging eyes. Smokers who have Graves’ disease risk having their eye condition get worse. They can also lose vision.

8. Pregnant? Smoking can harm your baby’s eyes.

If you smoke while pregnant, your baby is 5 times more likely to get bacterial meningitis as a child. This is when tissues around the brain swell. Meningitis can cause eye infection(s) and other vision problems.

Also, smoking during pregnancy increases your risk of giving birth too early. Premature birth can lead to a serious eye problem called “retinopathy of prematurity.” The baby may have permanent vision loss or blindness.

Toddlers and children are also at risk from secondhand smoke—a new study suggests children as young as 6 years old already show signs of eye damage.

Avoiding smoking and second-hand smoke—or quitting if you are a smoker—are some of the best investments you can make in your long-term eye health
