An old man who watched videos too much actually became 2300 degrees myopic! Experts remind you: You may also have these habits

Recently, a piece of news that "70-year-old man watched short videos and his myopia reached 2,300 degrees" became a hot search. The family members revealed that the old man never put down his mobile phone from morning to night. He should be at the age of "presbyopia", but he was suffering from severe myopia.

As a high-risk group for eye diseases, how can the elderly use their eyes scientifically while enjoying the convenience and entertainment brought by modern technology? What are the common misunderstandings about eye use in daily life?

Although vision will stabilize after the age of 18 as the eye develops, this does not mean that you can use your eyes without restraint. Excessive use of the eyes or pathological myopia may still lead to continued vision loss.

It is worth noting that myopia and presbyopia are not mutually exclusive, and both may be related to age and lifestyle habits.

Myopia is a refractive error caused by the elongation of the eye axis, while presbyopia is a decrease in refractive power caused by the aging of the lens and ciliary muscle, which generally worsens with age. Myopia and hyperopia patients may develop symptoms of presbyopia at a certain age.

Staring at the screen of a mobile phone for a long time in a dim environment will cause the eyes to be constantly irritated by the changing light and shadow. In the long run, this may cause dry eyes, deepen myopia or astigmatism, and even induce acute glaucoma. For the elderly, this bad habit may also increase the possibility of macular degeneration and cataracts.

In addition, lying down and looking at the phone is also one of the "culprits" of decreased vision.

Lying sideways to watch the phone may seem comfortable, but it is more likely to cause vision loss. Doing so for a long time will not only cause visual fatigue, but also lead to dry eyes, early onset of myopia or rapid increase in myopia, and even develop into high myopia.

When lying flat, because the eyes are closer to the bottom of the phone, more adjustments are required, which can cause eye muscle spasms and rapidly worsen myopia. In the long run, this may lead to high myopia or induce strabismus.

Experts from Zhuzhou Aier Eye Hospital remind you: If you love watching videos, it is recommended that you pay attention to the following eye protection habits!

1. Exercise more, especially outdoor sports and exposure to sunlight. Badminton, table tennis, and tennis can exercise the eye's ability to adjust.

2. Don’t turn on the night light when sleeping. The light affects the body’s secretion of melatonin and affects the development of children’s visual function.

3. Squeeze your eyes hard. You can squeeze your eyes 10 times every 40 minutes to stay away from dry eyes syndrome.

4. Apply hot compress to dry eyes to speed up blood circulation in the eyes, remove the metabolic products of lactic acid and creatine, and relieve visual fatigue.

5. Look far away to relax the ciliary muscles, slow down the progression of myopia, and relieve visual fatigue. Look far away for 20 seconds at a distance of 20 feet (6 meters) every 20 minutes.

6. People with severe myopia should avoid extreme sports and intense confrontational sports to prevent fundus lesions.

7. When studying and reading books, keep your eyes at close range, and keep the distance between your eyes and the book, your body and the table, and your fingers and the tip of the pen, one inch.

8. Eating less sweets is good for your eyes.

9. Supplement lutein. Lutein is an important element in the macular area of ​​the human retina. It can be supplemented through food supplements, such as spinach, cabbage, pumpkin, peach, pepper, mango, etc. Or it can be supplemented through other products.
