Worldwide, at least 2.2 billion people have impaired near or distance vision. However, at least 1 billion of these suffer from preventable or untreated vision impairment, including cataracts, age-related macular degeneration, glaucoma, and more. You may not think that smoking is a risk factor for visual impairment and blindness, and is closely related to the development of these eye diseases.
cataract, cataracts are usually characterized by a clouding of the lens that, over time, causes progressively blurred vision. Cataracts are the leading cause of vision loss in older adults and also contribute to an increased risk of falls. Most cataracts develop with age and are influenced by a variety of factors including tobacco use.

macular degenerationMacular degeneration is a common eye disease, especially in the elderly, that can severely and irreversibly damage vision, affecting the ability to read, drive, face and color recognition, and finely observe objects.
Smoking is a major modifiable risk factor for macular degeneration; smokers may have a 2- to 4-fold increased risk compared with never-smokers.
glaucoma, glaucoma is a progressive optic neuropathy that causes gradual loss of vision and is one of the leading causes of irreversible blindness worldwide. Studies have found that smoking may increase the risk of developing glaucoma compared with people who have never smoked.
On the one hand, smokers have a higher risk of eye disease compared with never smokers, and this higher risk is even more pronounced among current smokers compared with ex-smokers.
On the other hand, quitting smoking can also reduce the risk of developing other chronic diseases, such as cardiovascular disease and diabetes, which also lead to impaired vision.
Not only that, but tobacco smoke can irritate the eyes and worsen ocular symptoms (such as dry eye syndrome) in exposed non-smokers, especially those who wear contact lenses. Therefore, quitting smoking can also protect the eye health of others.

Let the eyes “move” by doing some simple eye activities, such as turning the eyeballs clockwise and counterclockwise 10 times following closing the eyes, which can relax the eye muscles and relieve eye fatigue.
At the same time, looking into the distance can also effectively relax the eyes. After sitting for a long time, you can also stand up and do 10 jumping jumps, and then do 10 hard eyelid closing and opening, and you can also use your head to write “米字” to move your cervical spine.
In addition, when carrying out daily regular physical activities, you can also choose to play ball games, so that the eyes can continuously relax and contract the eye muscles when the eyes are following the target, improve the blood perfusion of the eyes, and promote the metabolism of the eyes.
Ensure eye nutrition supply Balanced nutrition is beneficial to eye health. Protein, vitamin A, vitamin B1, calcium, selenium, etc. are all nutrients that are beneficial to the eyes.
Eat more fresh vegetables and fruits, such as broccoli, carrots, spinach, lettuce, oranges, grapefruit, kiwi, strawberries, etc., and eat less sweet and spicy food.
