[Ah, eyes are so sour…]
How many people have made such exclamations to mobile phones and computers, and then… then look at the screen.
Although we all know that looking less at electronic products can relieve eye acid; However, in the Internet age, electronic products are indispensable for adults to work and children to study.
What’s more, mobile phones and tablets are so fun, how can you give up?
Mobile phones and tablets cannot be separated from each other. What should I do with acid, swelling and pain in my eyes? Today, let’s invite expert Jin Xin to talk about common eye protection mistakes and correct eye protection methods.
The eye protection mode is not necessarily eye protection, and these three eye protection methods are unreliable.
1. Look more at green without eye protection.
Many people change wallpapers to green or put green plants on the table in order to [protect eyes]. The so-called [bean paste green eye protection tone] configured by ophthalmologists has also been on fire online for some time.
People think that green can protect their eyes simply because they feel relaxed when looking out of the window at the green plants. But in fact, it is not the [green] outside the window that relaxes the eyes, but the [outside the window].
If you want your eyesight to get by, you don’t have to be a little green.
It is better to look at the high-rise buildings in the distance and think about which one to buy in the future than to turn the work station into a primeval forest.
2. Food supplement cannot improve eyesight,
My parents will tell us from an early age that pork liver improves eyesight, eating fish eyes to supplement eyes, and making tea with medlar and chrysanthemum is good for eyes.
Although pork liver and fish eyes are delicious, they have little to do with improving eyesight.
In the past, when living conditions were poor, people could not eat meat and often suffered from dry eye and night blindness due to lack of vitamin A. Pig liver is rich in vitamin A, which is why it is called “pig liver improves eyesight”. However, eating pig liver does not relieve asthenopia, let alone improve myopia.
In addition to water and fat in fish eyes, the rest is a small amount of vitamin A and DHA. The so-called [eating what to supplement what] is only a psychological comfort.
As for drinking such a little medlar chrysanthemum tea, there is no scientific basis to prove that it has a protective effect on eyesight.
3. Don’t rely too much on the eye protection mode of mobile phones,
At present, the eye protection mode of mobile phones mostly uses algorithms to filter part of blue light, making the screen yellow and dark, and making it look less dazzling.
However, the damage of blue light to eyes has not been determined at present, so the eye protection mode may not be [eye protection].
If you want to protect your eyesight, the key lies in the time you use your eyes.
If you already feel your eyes are tired and ready to rest, and as a result, you have played for a few more hours because you have opened the eye protection mode, then it has really become the “eye destruction mode”.
Mobile phones and tablets cannot be separated from each other. Only by doing these things can injuries be reduced.
If you can’t help playing with your mobile phone tablet, you can reduce the damage to your eyes through the following points.
Step 1 Turn on the light
If you must look at the screen, don’t hide in a dark room.
After turning off the lights, the pupil of the human eye will spread out in the dim light and will be more stimulated when watching the light on the mobile phone screen. Not only will it increase asthenopia, but it may also induce glaucoma.
Therefore, when looking at mobile phones, tablets and computers, it is best to turn on the lights to improve the eye environment.
Step 2 Blink more
Staring at the screen for a long time, people often forget to blink because they are too focused.
Human eyes need to blink to evenly smear tears on the cornea. If they do not blink for a long time, tears on the corneal surface will evaporate, which is easy to cause dryness of the eyes.
If you don’t correct the habit of blinking, you may also cause dry eye and other problems. To reduce eye discomfort, you must blink at least 15 times per minute.
3. Remember the 20:20:20 rule
The 20:20:20 rule is a very simple and easy-to-remember eye rule, which can effectively relieve eye fatigue.
How to use it?
Remember: Every 20 minutes of work, raise your head and look 20 steps (about 6 meters away) away for 20 seconds.
Step 4 Use the correct posture
We were taught from an early age to do [one foot, one inch, one punch] when reading and writing.
This posture is very eye-friendly. When you reach the working age, you should also ensure that you sit upright.
The computer screen should be at least one arm away from the eye and ensure that the screen is slightly lower than the line of sight.
Friends who use notebooks had better have a keyboard to avoid leaning forward and being too close to the screen.
5. Take off your contact lenses and breathe your eyes
Although it is said that the current contact lenses have improved their materials and greatly increased their oxygen permeability. However, the indoor air circulation is not very good. Turning on the air conditioner in summer will further accelerate the evaporation of tears in eyes, causing eye discomfort.
Therefore, it is recommended that you use frame glasses when you need to use your eyes for a long time.
6. Drop appropriate eye drops according to the doctor’s advice.
At ordinary times, I feel tired with my eyes. Many people will buy eye drops casually and use them. After using them, I feel cool and comfortable, and my eyes relax.
However, eye drops are potions after all. No matter whether they are what functions, they are not recommended to be bought and used at will.
If you really feel uncomfortable with your eyes, you should first check your eyes and use the right drugs according to the doctor’s advice to avoid wrong use and delay your illness.
7. Choose electronic products with high visual health and comfort
Prevention of blue light does not necessarily [prevent] the damage of mobile phones and tablets to eyes. In addition to correcting eye habits, can we only protect our eyes by looking at less electronic products?
In fact, you can also choose more [eye-protecting] electronic products.
The Chinese Institute of Standardization has developed a set of models for objective evaluation of asthenopia, which is called “Visual Comfort Evaluation Index (VICO Index)”.
The biggest difference of this set of evaluation criteria is that it is not based on the physical properties of the light source, but on the functional state of the human eye, so it is more in line with the intuitive feeling of the eye. When selecting lamps, glasses and electronic products, we can judge whether we can protect eyes according to its VICO index.
How do you judge?
Look at these two forms to understand:
In other words, the smaller the VICO index, the higher the visual health comfort of the product.
For electronic products that are easy to tire eyes, if the visual health comfort level of the products can reach above B +, they will feel much more comfortable to use.
