Tips to protect your eyes: 1. Develop a good habit of using your eyes and be sure to watch less TV, mobile phones, computers and other electronic products.
Second, watch more green things and do eye exercises. Third, keep the distance between books, don't use your eyes for a long time, pay more attention to rest and avoid staying up late.
fourth, the indoor lighting brightness should not be too high. 5. Eat more foods that protect your eyes: In order to protect your eyes, you can eat foods rich in vitamin A, such as fish, animal liver, seafood, cream, eggs and carrots to prevent night blindness, xerophthalmia and keratomalacia in children.
Eat more fruits that are good for your eyes: blueberries (rich in vitamins, amino acids, minerals and anthocyanins, which can improve your night vision). Cherry tomatoes (containing va, VC and VP, with strong antioxidant capacity), kiwifruit (king of VC, preventing cataracts) and apples (eyesight improving fruit, containing va and trace element selenium).
Eat more fruits containing vitamin A: loquat, cherry, banana, longan, apricot, litchi and so on. Eat more foods rich in lutein: corn, spinach, cabbage, broccoli, egg yolk, pumpkin, carrots, etc. Fruits include mango, kiwi, grapes, oranges and tomatoes.
2. Use common sense
1. Stand somewhere, find a distant tree and a near tree, then observe the nearby tree for a while, and then observe the distant tree for a while.
This method can regulate eye muscles and relax. Look at the details of the tree as much as possible when observing.
2. Rub your palm hot, cover your eyes and do it repeatedly, which is also relaxing and comfortable. This action can be done anytime and anywhere. 3, sunbathing, when the weather is fine, close your eyes and face the sun, let the light pass through the eyelids, * * * eye cells.
We nearsighted people are very sensitive to light, and we squint or squint when we encounter strong light. Doing so can improve our eyes' ability to accept light.
4. At night, when there are stars in the sky, count them and look for them with your eyes, but don't stare at a star all the time, so your eyes will get tired. 5. Sit or stand, look straight ahead, then move your eyes up, down, left and right, and let your eyes stretch in every direction as much as possible, just stay for a few seconds in each direction.
We will find that our eyes are deformed after nearsightedness. This method can adjust our eyes back to normal shape and help to restore their focusing ability. 6, blink more, blinking can relieve eye fatigue, this is to be done at any time.
I just combine these methods and do them every day when I have time. Because I am relatively free, I spend a lot of time doing it every day, perhaps because of this, my eyesight will make such rapid progress.
If you don't have much time, you should take some time to do it every day. It is estimated that the time will be longer, but it will definitely change. If you want to take off your glasses, then everyone should try not to wear them.
Maybe most people, like me, have always had the wrong understanding that myopia will deepen without glasses. In fact, this is wrong. Without glasses, our vision can be restored, so we can not wear them without interfering with our normal work and study.
At first, I was very uncomfortable without glasses. My eyes were blurred and I couldn't see anything clearly. I had to stick my head in everything I wanted. Although I looked a little silly, after a long time, I gradually got used to this fuzzy world. But with the recovery of my eyes, my world becomes clearer and clearer.
I haven't worn glasses for more than a month. I don't wear them at home or outside, playing computer or watching TV. It doesn't matter if you can't see clearly, as long as you get clearer and clearer.
By the way, when we look at things without glasses, we will have a habit of squinting or glaring in order to see things clearly. Attention, everyone, don't do this. Once you find your eyes narrowed, stop immediately.
If you can't see clearly at this time, blink more. To restore our vision, the above methods are necessary, and it is very important to relax.
one is physical and eye relaxation, and the other is psychological relaxation. We should believe that our eyes will get better, and we can't worry.
everyone's situation is different, so the recovery time is different, some months, some more than a year, it doesn't matter, the key is persistence, although the action is simple, you must do it every day. I do it every day when I am free, and these methods are combined with each other, and the practice time is uncertain.
There are many ways. You can check books and materials online and experience for yourself. I hope everyone can take off their glasses and work together. If you are effective after practice, please tell your friends and ask them to take off their glasses as soon as possible.
3. Common knowledge about glasses
The easiest way to test the glasses' degree is to look at the light sideways, and the aperture is about 5 degrees. The following is what you need to know about glasses. Contact lenses: There are many contact lens brands on the market at present, and each brand is divided into different categories according to its performance.
each kind of lens has different characteristics, and the diversification of varieties and functions brings difficulties to consumers' choice. which one is reassuring? First of all, when choosing lenses, we must pay attention to whether a certain brand has a registration certificate issued by the State Food and Drug Administration. The State Food and Drug Administration adopts ISO international standards to test the functions of lenses, such as the damage degree of lenses to cornea, the process of grinding lenses, the materials used and the water content and air permeability of lenses, so the quality of brands with registration certificates is generally guaranteed.
Secondly, attention should be paid to the degree, size, material and service time of lenses. Many people think that the degree of frame glasses and contact lenses are exactly the same, so they often buy contact lenses according to the degree of frame glasses.
In fact, this is not right, because for the same eye, there is a difference between the power of contact lenses and the power of frame glasses, and the higher the power, the more obvious the difference is. Generally, there is little difference between the lenses below 4 degrees, and the lenses above 4 degrees need to be added or subtracted.
The power of contact lens used to correct myopia is lower than that of frame glasses. For example, the optometry result is 45 degrees of myopia, and the contact lens needs to be reduced by 25 degrees, just 425 degrees. The contact lens used to correct hyperopia has a higher degree, for example, the optometry result is 45 degrees hyperopia, and the contact lens needs to be increased by 25 degrees, and it needs to be matched with 475 degrees.
The size of the lens is generally determined according to the size of the black eyeball of the wearer. People with larger black eyeballs should choose larger lenses, while those with smaller black eyeballs should choose smaller lenses. People who are prone to dry eyes should choose contact lenses with low water content.
people who often work in the sun can choose lenses with anti-ultraviolet function. Generally, people who are allergic, who often contact cosmetics and who are often in a dusty environment are more suitable to wear disposable contact lenses.
Ordinary spectacle frames: China has become the country with the highest incidence of myopia in the world. According to statistics, the population suffering from myopia in China has reached more than 3 million, accounting for about one third of the world's myopia patients, and its ranking in the world has jumped from the fourth place in 1998 to the second place now.
According to statistics, the proportion of nearsighted people in Shanghai ranks first in big cities in China, among which the myopia rate of primary school students is 28%, that of middle school students is 38%, that of high school students is 58%, and that of college students is as high as 8%. When you want to match yourself with a pair of glasses, the word "appropriate" is the most appropriate.
frames. For people who need to wear glasses, the purchase of frames is very important.
when choosing glasses, consumers should not only consider the face shape, the bridge of the nose, the distance between pupils and glasses, but also coordinate with skin color and hair color, so as to wear temperament and grace. Generally speaking, people with wide faces should not use small and narrow frames, and people with long and thin faces should not use wide frames.
For children, it is best to choose a plastic frame, and it is advisable that the frame can be attached to the nose. For some consumers with high myopia and hyperopia, due to the high diopter, they should generally choose small frames, and the smaller the lenses, the better.
There are several commonly used spectacle frames: plastic frame, metal frame and nylon wire frame. Compared with frames, there are far fewer kinds of lenses, but their quality is the decisive factor to measure the quality of a pair of glasses, so consumers must be careful when purchasing lenses.
glass lens: wear-resistant, but relatively speaking, its weight is heavier than other lenses, and it is also easy to break. Polymer resin lens: this kind of lens is lighter than glass lens, resistant to impact, and not easy to break, but its hardness is low, so it is easy to fluff and scratch.
besides the material, the quality of a pair of glasses depends on the refractive index of the lens. The higher the refractive index, the thinner the lens and the higher the price.
4. What do you know about eyes?
Hello, landlord!
Because there are many people surfing the Internet now, I'd like to tell you something to pay attention to when surfing the Internet:
● Rest your eyes every hour and don't keep operating.
● When using the computer continuously, blink frequently to prevent dry eyes.
● The distance between the eyes and the screen with a size of 35cm should not be less than 6cm, and the distance between the eyes and the screen with a size of 38cm should not be less than 7cm. The screen should be placed slightly below apparent horizon.
● Adjust the brightness and clarity of the screen to an appropriate level, subject to the comfort of the eyes.
● Always wipe the screen. Too dirty screen will blur the image and cause eye fatigue
Many people often feel dry eyes. How to prevent dry eyes? I found the answer on the Internet, so you might as well have a common sense.
There are two reasons for dry eyes.
One is that the supply of tears is reduced, and the other is that the evaporation of tears is increased. The reduction of tears is a characteristic of modern people.
Tears are difficult to flow out under tension, and decrease at night. Tears also decrease with age. There are more and more factors that reduce tears, such as office automation equipment, the lifestyle of night owls, the increase of social pressure and the dryness caused by the popularization of air conditioners. In addition, the reasons for the increase in evaporation are as follows: the number of blinks decreases due to staring at the pictures of personal computers and game machines; The oil layer located on the surface of tears has become unstable for some reason. The oil layer is secreted from the sebaceous glands of the eyelid at the edge of the eyelid, but it is often blocked. If you use a towel to hot compress your eyes, it will improve blood circulation and eliminate eye muscle fatigue.
There are several ways to prevent and treat dry eyes:
(1) consciously increase the number of blinks;
(2) enlarge the monitored text, lower the picture, and don't open your eyes too wide;
(3) Don't face the air of the air conditioner;
(4) increase the humidity around the eyes;
(5) Use artificial eye drops;
(6) hot compress eyes, etc.
Eye-care:
Pay attention to a balanced diet at ordinary times, so as to ensure the supplement of trace elements and vitamins, eat more fresh vegetables, fruits and seafood, and eat less sweets and sweets.
extreme eyes:
in the morning, stand naturally in a place with fresh air. First, look straight at a distant target with your eyes, then slowly take back your eyes. When the distance from your eyes is 35 cm, then shift your eyes from near to far to the original target. Repeat this several times, and then take a deep breath exercise, which is good for regulating eye function. Ironing purpose:
Every morning or before going to bed, take a sitting or standing position, close your eyes, quickly rub your palms and get hot, and then quickly press them on your eyes, then you will feel a warm current in your eyes. Repeated several times, it can dredge meridians and improve blood circulation in the eyes.
Bath eyes:
Bath your eyes with hot water, hot towel or steam once or twice a day for about 5 minutes each time. It can also be combined with washing your face and drinking hot water. It can also be used to decoct Chinese medicine such as chrysanthemum and bamboo leaves to get juice, smoke your eyes while it is hot, and then wash your eyes with the medicine after the water temperature is high, which has the effect of clearing heat and improving eyesight.
Eye movement:
Standing in front of the window, staring at the upper, lower, left and right corners of the window in turn clockwise or counterclockwise can relax muscles and activate eyes, improve eyesight, and do it for 5-1 minutes every morning and evening.
eye-nourishing:
Chinese medicine believes that the liver is open to the eye, and the liver can be seen with blood, and the eyes of animals can be filled with eyes, so eating more animal liver can effectively protect the eyes, such as pig liver and egg soup, fried pig liver with onion, stewed animal eyes with qi, stewed pig eyes with lean meat, and fish head with mushrooms, which can be eaten frequently.
