Presbyopia is like gray hair and wrinkles, which are all signs of aging. With age, the lens of the eye will gradually age, the elasticity will become worse and worse, and the ability to regulate will decrease, resulting in old vision.
Presbyopia is something that everyone has to go through. This usually happens to people after the age of 60.
But with the rise of electronic products, presbyopia tends to be younger, and a considerable number of people have presbyopia in their 40s.
What factors are involved in the occurrence and development of presbyopia?
1. Improper use of the eyes
Eye distance will affect the need to adjust, and people who do close and delicate work for a long time are prone to presbyopia.
In addition, playing with mobile phones or computers for a long time will reduce the number of blinks, increase eye fatigue, and make the eyes unable to obtain enough tear water, thereby generating a large number of reactive oxygen species, destroying normal eye cells, and accelerating the formation of presbyopia.
2. Refractive error
Studies have shown that presbyopia occurs earlier in hyperopia patients than in myopic patients, because myopic patients wear glasses to reduce the need for close-up use and conditioning.
In addition, long-term use of anti-anxiety, antidepressants and antihistamines, insulin injections, taking diuretics and antispasmodic drugs can affect the ciliary muscles and lead to premature presbyopia.
How to self-test presbyopia?
Without glasses, you can't see the keys and text on your phone; when reading articles, it's easy to serialize, and there will be ghosting when reading text;
You need to put your phone or book at a distance to see clearly; when you alternately observe objects from far to near, the focus time is relatively long;
In the past, I used to wear myopic glasses to read books, but now I can only read the words on the books if I take off my glasses; you have to increase the brightness of your phone to see clearly. If there is the above phenomenon, you should be highly suspicious of the appearance of presbyopia.
How to delay the occurrence of presbyopia?
1. Do not overuse the eyes
Middle-aged and elderly people should spend less time playing with electronics. They should look at their computer or phone every hour for 10 to 15 minutes of eye exercise or outdoor overlook. Sleep at least 7 to 8 hours a day, avoid staying up late, and let your eyes get enough rest.
2. Adjust your diet
Nourish the eyes with foods rich in vitamin A, carotenoids, and B vitamins, such as carrots, mangoes, offal, eggs, legumes, and milk. Eat less or no spicy and greasy foods and stay away from foods high in salt and sugar.
3. Improve the eye environment
Indoor lighting should be appropriate. The light should not be too strong, but it should not be too weak, otherwise it will affect vision. When you're in the car, walking, or lying down, you can't hit your phone or read a book; you can't read a book with a small, blurry font.
4. More eye rotation
Leisure time can make the eyes rotate counterclockwise and clockwise, promote local blood circulation and relieve eye fatigue. In addition, you can gently massage your eyes with your hands, which can strengthen your eye muscles and relieve eye fatigue.
5. Maintain moderate exercise
Middle-aged and elderly people should participate in outdoor activities, such as brisk walking, jogging, cycling or tai chi, which help regulate eye muscles, strengthen resistance, and delay the occurrence of presbyopia.
6. Wear sunglasses when going out
Ultraviolet rays are stronger in summer. When going out, you should wear sunglasses or a wide-brimmed hat to avoid ultraviolet rays hitting your eyes, otherwise it will accelerate the aging rate of your eyes.
If it is presbyopia, please choose a regular optical shop or eye hospital for optometry and wear appropriate reading glasses.
Long-term wearing of inappropriate glasses can cause insomnia or dizziness in the elderly. In addition, the elderly will not be able to wear the same pair of glasses for a long time, which will cause dizziness.
