In the age of the Internet, many people stare at their cell phones and computers all day long.

The most hurt would be the eyes, more or less uncomfortable, such as dry, sore, itchy ......

Is there anything I can do to alleviate these discomforts?

Before we get to the answer, let's first answer a query ......

Why is it hard on the eyes?

Simply put, it's because the eyes are too busy.

Normally, we blink about 15 to 20 times per minute, almost every 5 seconds. Each time we blink, tears cover the surface of the eyeball and moisturize it.

However, when the eyes are busy looking at the computer or cell phone, the number of blinks will be significantly reduced, due to the lack of tears to moisturize the surface of the eyes dry, over time, naturally appear dry, photophobia, soreness and so on.

So here's what works best: give your eyes a break.

It is said that there are little ways to protect your eyesight, such as looking at the color green, rolling your eyes, and eating goji berries...really?

Seeing all kinds of green stuff?
Doesn't work ......

I heard that looking at the green have good for the eyes, many people have their cell phones, computer screens, replaced with green, and even specialize in finding a green picture on the computer next to.

For example:

There's also this ......

Staring ...... staring ...... a little dizzy ......

In fact, it doesn't matter if the screen is green, the background is green, and it's surrounded by green ...... as long as you still keep staring close up.

That's because the eyes are still doing serious work.

If you really want to see green, blink and go look at the trees outside your window.

Rotating eyeballs?
Doesn't work ......

Follow me left eye right eye in one slow motion! Right eye left eye slow motion replay!

Come on, follow these little balls around a few more times.

Is it getting dizzy and hard on the eyes the more you spin? That's because it's working harder.

It doesn't matter how many times you rotate your eyes if your eyes still haven't left your computer or cell phone, or if you still keep staring at the near distance.

The key to taking care of your eyes is not to roll your eyes, but to let them rest.

Have some goji berries?
Not very useful ......

Among the many benefits of goji berries, eye-improvement is one that is often mentioned because it contains lutein, which is beneficial for eyesight.

But! Lutein is very limited.

Lutein does not solve all eye problems. It is only useful for the prevention and treatment of eye diseases such as vision loss and blindness caused by "age-related macular degeneration" and cataracts.

The amount eaten every day is too small. Every 100 grams of goji berries contain about ten milligrams of lutein, and the average person eats only a few per day, which is a very limited amount.

If you like it, there's no harm in eating it.However, counting on eating goji berries to improve vision and relieve visual fatigue is not very useful and does not get to the root of the problem.

Proper eye care should be done like this

The key to protecting your vision is to give your eyes a good rest and not to strain them too much.

Remember the 20-20-20 rule.

For every 20 minutes of computer use, look at least 20 seconds into the distance of 20 feet (6 meters). If you are too busy to take frequent breaks, it is recommended that you take a 5-minute break after 45 minutes of continuous eye use.

This is a good question, and Dr. Zhang has also reviewed some literature and related information. Some literature shows that: green due to shorter wavelength, imaging in the retina before, can prompt the eye ciliary muscle rest, reduce eye fatigue. Frequently looking at the green color is beneficial to vision care. However, the green color here refers to the green color in the distance, not the green color in the near distance. If you put green things within 33 centimeters, it still does not have a relaxing and resting effect on your eyes.

In fact, much of the literature points to the fact that it is even more important to protect your vision by paying attention to these details in your life.

1, when reading books should pay attention to the light, the light must be sufficient and comfortable, otherwise the light is too weak and because of the font can not see will damage the eyes.

2, objects reflecting on the eyes have damage, so in reading, watching TV, playing computer, etc., pay attention to adjust the light.

3. Don't read or watch TV or cell phones for too long.

4, reading books, watching TV and cell phones, the distance should be moderate.

5, pay attention to rest, sleep time do not reduce.

6. Do more outdoor exercise and walk outdoors more often.

7. Nutrition should be balanced.

8. Regular vision checks.

Dr. Zhang feels that if you can do all of the above, you may be able to protect your eyes better than just looking at the color green.

Thanks for the invitation!

Does looking away and looking green help prevent myopia?

It can be said quite categorically thatNo!

What is myopia?

We know.The eye is like a camera in that the light is focused by the cornea and lens at the front of the eye and projected exactly on the photoreceptors at the back of the eye.on the retina in order to present a clear image.

If the light is not precisely focused on the retina, it fails to present a clear image and is called a refractive error.

If it is focused in front of the retina, it is myopia. Focusing behind the retina is hyperopia.

How does myopia occur?

The usual myopia is due to the fact that the front and back (longitudinal axis) of our eyes are too long and thus the light falls in front of the retina.

Why are eyeballs overstretched?

In fact, at birth, the longitudinal axis of the eye is relatively short, and the focused image falls behind the retina and does not get a clear image, so early in life, we are all farsighted, called physiologic hyperopia.

After birth the eye develops and grows like other tissues and organs, and the longitudinal axis of the eyeball gradually lengthens until theformation of a normal refractive error.This process is primarily accomplished in infancy and early childhood.

However, eye growth is not "smart enough" to form a normal refractive growth will stop. In fact, the elongation of the longitudinal axis of the eye continues after childhood, a process that occurs mainly between the ages of 5 and 16 years and usually stops completely after 19 or 20 years of age.

This process, in which the eyeIn the event ofOverstretch and myopia happens.

What factors control the elongation of the eyeball and influence the onset and progression of myopia?

Although, the exact mechanism of ocular elongation control is not fully understood.

However, the elongation of the eyeball is part of the developmental growth of the body. So, fundamentally, the primary regulatory code program is written in our DNA.

Some of these people have this part of the code written in such a way that the eyeballs are more likely to be overly elongated, which is the genetic component of myopia.

As for environmental factors, there may be diversity.

There have been many scapegoats for the environmental "culprits" of myopia, including:Close up vision, vision in overly bright or dark environments, prolonged vision (visual fatigue), and even watching TV and looking at cell phones.

still, these factors have been notoriously undermined by well-designed controlled studies.

At present, the only environmental factors identified by scientific research as contributing to the development of myopia are insufficient outdoor activities, prolonged periods of time indoors in low-light environments, and insufficient light stimulation (especially ultraviolet B light) for the retina to secrete the biologic factors that regulate the growth of the eye, which are now believed to be primarily dopamine, resulting in insufficient secretion of the regulatory factors.

It is known that factors such as dopamine inhibit the elongation of the eye, and insufficient secretion leads to insufficient inhibition of the elongation of the eye, resulting in excessive elongation, leading to the onset of myopia and its further development.

This process can continue until you are about 20 years old.

Looking away and looking green does not prevent the development of myopia

In terms of the onset and progression of myopia described above, looking away and looking at the color green do not have any effect on the elongation process of the eye, and thus do not prevent the development of myopia.

However, looking away is one of the effective ways to prevent visual fatigue, especially effective for visual fatigue caused by prolonged viewing of digital displays.

Often, it is thought that visual fatigue is primarily the result of tension spasms in the extraocular muscles caused by looking at a single target for a long period of time. In fact, it is more predominantly the result of prolonged visualization, especially highly concentrated gazing, that interferes with the blinking of the eye, a program that humans come with to prevent visual fatigue.

We know that the surface of the eye is uniformly coated with a protective film - the tear film - formed by a mixture of tears (aqueous solution) secreted by the lacrimal glands, and oils secreted by the levator palpebral glands (which slow down the evaporation of tears), and that we maintain the integrity of the tear film by blinking constantly.

When we stare at the target gaze for a long time, blinking interrupted, the tear film will rupture, the sensitive corneal cells on the surface of the eye will be directly exposed to the dry and unclean air, which triggers the corneal cells of the self-warning and protection mechanism, appearing to feel the eye discomfort, dryness, can also occur neurogenic inflammation, manifested as congestion and redness.

The important role of looking away frequently is not to relieve tension in the extraocular and ciliary muscles, as one might otherwise think, but to make the study stop, take a break, and blink.

Specific methods, usually recommended20-20-20 rule:

That is, at 20-minute intervals, take your eyes off your reading, especially your computer screen, and look at an object 20 feet (6 meters) away for at least 20 seconds.

Of the many recommendations.It says it's best to look at distant green objects, such as green leaves of plants, to be more conducive to relieving visual fatigue.

In fact.There is no evidence that looking at the color green helps relieve visual fatigue.

Looking at greenery to help relieve visual fatigue and even prevent myopia is a misconception that has existed in the population for a long time.

According to the results of the national students' physical health research, by 2020, China's population with vision problems may be as high as 700 million or more, especially the student population, myopia population ratio is rising year by year. Yesterday, June 6 is the 23rd national "Eye Care Day", this year's "Eye Care Day" activity theme is "scientific prevention of myopia, care for children's eye health".

To prevent myopia, it's not just a matter of looking away and seeing green, but of going into the distance and getting into the green

Studies have found that 2 hours a day and 10+ hours a week of outdoor activity can reduce the incidence of myopia in teens by one-tenth. It's best to make time every day and get out into nature, or if you just can't find the time during the week, make it up on the weekend ~ ha. For children who are not too fond of sports, simply staying outdoors in the sunny, also has the effect of preventing myopia oh~!

Daily diet, the "red and black" of myopia prevention

We usually use the eyes need to consume a variety of nutrients, only in a timely manner to make up for the consumption of nutrients, so that the eye tissues are protected, in order to prevent myopia, to protect the eyesight to play a fundamental role.

For the eyes, lutein and zeaxanthin, vitamin A and carotene, anthocyanins, B vitamins, vitamin C and vitamin E, calcium and zinc, these "eye protection essentials", in our daily natural food, especially orange, purple, red, green and other colorful foods, the content is very rich, and regular consumption is good for the prevention of myopia. Regular consumption of these foods can help prevent myopia and protect your eyes.

On the contrary, frequent consumption of sweets and beverages will consume a lot of vitamin B1, and it will lead to the loss of calcium, which will weaken the elasticity of the wall of the eyeballs, leading to the development of myopia.

In short, look away, look at the green, on the prevention of myopia will help, but more fundamental, more effective is often outdoor exercise, often eat rainbow food, in daily life, brighten the indoor light to reduce the burden on the eyes; can not see the blackboard to report to the teacher in a timely manner to go to the regular place of optometry; can not cell phones and tablet computers do not touch, not picky about what to eat, go to bed early and get up early, not only is this the foundation of a healthy life but also the root of the eye! These are not only the foundation of healthy life but also the foundation of eye health.

First let's look at how the eye is able to see objects at different distances. Similar to a camera, the ability to see objects at different distances is achieved by zooming. The eye's ability to zoom comes from a structure inside the eye, called the lens, which changes its shape, flattening or bulging a little, to change the ability to refract light, thus making it possible to see objects at different distances clearly.

The main thing that changes the shape of the lens is the ciliary muscle. Generally speaking, when we look at the distance, the ciliary muscle is in a relaxed state; when we look at the near, the ciliary muscle will be contracted, which makes the suspensory ligament connected with it become relaxed, the lens will become convex, the refractive power will be increased, and the ability to converge the light will become stronger, which makes the eye can see the near objects clearly.

When looking at a near place for a long time, the ciliary muscle will be in a constant working condition of contraction, which will cause spasm of the ciliary muscle over time. Pseudomyopia, which is often mentioned, is actually caused by this fatigued state of the ciliary muscle.

After clarifying the above, the answer to this question also comes out. Looking away from the ciliary muscle is in a state of relaxation, can relieve the fatigue caused by looking at the near for a long time, so for the prevention of myopia is helpful; and look at the green, the ciliary muscle does not have any effect, so it can not prevent myopia.

Human beings are born from animals, and their ancestors came from the African savannah, so their eyes are adapted to look into the distance. It's good for the eyes to look far away and see green. This is also one of the reasons why some good girls, who do not stay at home, are nearsighted even though they do not play with their cell phones all day long.

谢邀.

I've personally experienced that looking away is good for the body and mind 🌍

Look at the green, emm, it's hard on the eyes if you look at it too long.

Seeing nature's flowers and trees is good for the mind and body 💐

Look far away Look green, in fact, means: less look at the phone less play computer, more look around the scenery; do not always nest in their own small room, more go out to look at the blue sky, white clouds, flowers, trees, buildings and so on.

In an enclosed space, staring at a computer or cell phone screen and seeing green, I guess you're blind if you're not 🙈

Theoretically speaking, more greenery, more look away, useful for myopia control, but in fact the effect is very little, because more guarantees can not be guaranteed, unless do not read, do not do homework, do not watch TV, do not play the phone, living in the prairie, that may be useful! Instead of fantasizing, why not learn about some brand of smart glasses that might work wonders for your myopia control?
