Staring at computers at work, chasing variety shows on the road, lying in bed and brushing cell phones at home… All day long, eyes and electronic screens are inseparable.
Tired.
According to statistics, about 1-2 out of every 4 Chinese suffer from dry eye.
Do you have the following symptoms?
- Eyelid acid swelling, unwilling to open; Objects in front of us gradually blur and improve after blinking. Dry eyes, even pain, close your eyes and rest a little better; Tears in the wind, or sudden pain, tears, rest or improvement after closing eyes after working for a certain period of time.
If you are successful, you must be careful about these problems.
Watching the screen for a long time leads to dry eye.
Modern people’s life cannot be separated from all kinds of screens. It is likely that they will stare at it for a whole day, with dry and astringent eyes and even red blood streaks.
Why do your eyes feel uncomfortable after watching the screen for a long time? There are two main reasons:
Step 1 Blink too little
Under normal circumstances, we blink 15-20 times per minute. Every time we blink, we will spread a layer of tears on the surface of the eyeball to form a tear film.
This layer of tears is the key to ensure that the eyes are not dry.
However, when we stare at the screen attentively, the number of blinks will decrease. The moisture in the tear film evaporates and is not supplemented by blinking. If the eyes are not moist enough, dryness, fatigue and even pain will easily occur.
Step 2 Overuse your eyes
The eye is like a camera, and the ciliary muscle is the focus.
If you keep staring at things close to you, the ciliary muscle will always be in a state of tension and difficult to relax. After a long time, you will not be able to see clearly and even deepen myopia.
Many people want to use some tips to relieve eye discomfort, such as massage, hot compress, and changing an anti-blue screen … Are they really useful?
These methods are unreliable.
1. Massage and eye stickers
The above mentioned two causes of eye discomfort, while massage and eye patches can neither relax ciliary muscles nor make you blink more.
Strictly speaking, they do not have therapeutic effects, and there is no literature to prove that these two methods can protect eyes.
Some people really feel much more comfortable after massaging and using eye patches because…
They take your eyes off the screen and have a good rest.
2. Anti-blue glasses, mobile phone eye protection mode
In order to protect eyes, many people will buy glasses with blue light prevention effect, but they don’t need them.
Blue light with a wavelength of 400 nm ~ 480 nm may indeed damage retinal cells. However, in daily life, the intensity, quantity and irradiation time of blue light are far from the amount in experiments.
Talking about injuries without dose is all hooliganism. [Using anti-blue glasses to protect eyes] is currently only at the conceptual level and has no practical effect.
Similarly, the eye protection mode of mobile phones is not necessary. Moreover, the eye protection mode is generally low in brightness. If it is used during the day or under strong light, it takes more eyes to see the contents on the screen clearly.
With this kung fu, it is better to put down your mobile phone and try the following small methods.
These methods are simple and effective
Step 1 Blink more
Consciously blinking more, closing more eyes and resting more are the first choice to relieve fatigue.
Step 2: Hot Compress
In addition to secreting tears, eyes can also secrete a small amount of grease, helping to keep moisture and reduce evaporation of tears. However, sometimes the glands that secrete grease will be blocked, causing eye discomfort.
Applying hot towel to eyes can dredge blocked glands and effectively relieve dryness of eyes.
Step 3 Look at the distance for a while
When looking at mobile phones and computers, ciliary muscles will always be in a state of tension because of their close distance.
It is suggested to look at the distance (e.g. Outside the window) every once in a while to relax your eyes.
Step 4 Adjust the computer position
When using a computer, the eye is preferably half a meter away from the screen, and the center of the computer is about 15 cm below the eye.
Step 5: Artificial Tears
As the name implies, artificial tears are the use of various materials to simulate natural tears. Their ingredients are relatively simple and have few side effects. Among them, artificial tears without preservatives are safer and are currently internationally recognized drugs for treating dry eye.
Generally speaking, dry and sore eyes can be recovered as long as they have a full rest. However, if all the above methods have been tried and still do not work, it is better to see a doctor as soon as possible.
Don’t forget to tell these little knowledge of eyes to your friends.
Use your eyes moderately, and it will take you to see the larger world.
