What causes eye strain? What are the symptoms?

The symptoms of eye fatigue include dry eyes, astringent eyes, tears, dazzling eyes, blurred vision, dizziness, head swelling, and the causes of eye fatigue, generally presbyopia or eye hygiene, the so-called eye hygiene, a series of uncomfortable symptoms caused by excessive use of mobile phones and computers. We call this terminal syndrome, which is an emerging term. In order to alleviate this symptom, we must change our eye habits, we can use a hot towel to apply a local hot compress, if you look at the mobile phone and computer too much, it will also cause macular degeneration, and macular degeneration is generally not easy, so we repeatedly emphasize eye hygiene.

With the popularization of computers in work and life, some people often feel dry eyes and discomfort, and even dryness, photophobia, and blurred vision. These symptoms are not caused by pathological changes, but by improper use of the eyes. This is what we call eye strain, although it is also a relatively common symptom, but it will have a bad impact on our eyes in the long run.

Eyesight bilberry lutein can be used to care for the eyes, which contains a lot of eye nutrients, which can help relieve eye fatigue and moisturize the eyes.

Prolonged close-up eye use can cause eye strain, which is caused by the ciliary muscle being in a state of tension and contraction for a long time, which will eventually cause ciliary muscle spasm and cause accommodative myopia, and excessive visual fatigue will cause symptoms such as dry eyes, eye swelling and pain, and vision loss.

Condition analysis: The symptoms of eye fatigue include dry eyes, astringent eyes, tearing, dazzling eyes, blurred vision, dizziness, head swelling, and the cause of eye fatigue, generally presbyopia.

Or it is a series of uncomfortable symptoms caused by not paying attention to hygiene with eyes, the so-called lack of hygiene with eyes, and too many mobile phones and computers. We call this terminal syndrome, which is an emerging term. In order to alleviate this symptom, we must change our eye habits, we can use a hot towel to apply a local hot compress, if you look at the mobile phone and computer too much, it will also cause macular degeneration, and macular degeneration is generally not easy, so we repeatedly emphasize eye hygiene.

Dry and tired eyes are usually caused by more eye use at close range, or poor quality of tears, and less secretion of tears. If there are usually fewer tears, you can use artificial tear eye drops instead, such as sodium hyaluronate, polyethylene glycol or artificial tear eye drops such as Xiaolaiwei. If you use it for a long time, it is best to choose a preservative-free type, which will be relatively better.

Frequent close use of the eyes can cause eye fatigue and cause eye soreness and swelling pain, and anti-fatigue eye drops, such as Sturen eye drops, can be used to relieve eye fatigue. If you do face the computer more every day and often use electronic devices, you can consider wearing a pair of anti-blue light glasses and wearing them when using electronic devices, and it will effectively slow down or reduce the effect of visual fatigue.

If you feel particularly tired in your eyes, it may be due to dry eyes, refractive error, or visual fatigue. Eye muscle dysfunction can also lead to worsening eye fatigue, which can be examined and diagnosed at an optometry clinic.

There are the following reasons. It is necessary to choose different ** regimens for relief according to the cause of eye fatigue. Eyes for a long time:

Such as looking at the mobile phone screen and iPad screen for a long time. Refractive error: If there is myopia, farsightedness, astigmatism, etc., long-term use of the eyes when the vision is poor is easy to cause visual fatigue.

Dry eyes: If the secretion of tears is insufficient, dry eyes can also cause eye fatigue.

It is likely to be caused by playing mobile phones and watching TV for a long time, and it is also related to myopia and excessive eye use.

Long-term poor eye habits, combined with a lack of nutrients in the eyes, can lead to this.

Long-term overuse of the eyes, stiff eye adjustment, non-stop blinking, soreness, blurred vision.

Causes of eye strain, consider the following:

1. Factors of the eye itself: such as refractive error, including myopia, farsightedness, astigmatism, or visual fatigue with glasses, such as high myopia and insufficient farsightedness. In the elderly, eye fatigue can be caused by poor eye muscle accommodation, as well as eye diseases such as glaucoma, increased intraocular pressure, and supraorbital neuralgia.

2. Environmental factors: mainly insufficient or too strong light, which makes the light distribution in the eye uneven or flickering, reflective, etc., which can also cause eye fatigue.

3. Bad eye habits: long-term close use of eyes or looking at electronic products can easily lead to spasm of the ciliary muscle. At the same time, due to the reduction of blinking, it can cause symptoms such as dry eyes and fatigue.

There are three main causes of eye strain, which are as follows:

The first, most common, is refractive error, which includes nearsightedness, farsightedness, and astigmatism. If there is a small degree of myopia or farsightedness, it will be easy to get tired, if the eyes are not corrected enough, myopia, farsightedness, astigmatism, watching TV for a while is easy to cause visual fatigue.

The second type, heterophoria, is that the eye has a small degree of esotropia and exotropia, but it will not be noticed when you look at things normally. If this power is very small, but you need to fight this strabismus when reading a book or concentrating on something, it will cause visual fatigue over time.

The third is that the divergence function is not good, and the eyes are inward when looking near normally, and if this function is not perfect, it is easy to cause visual fatigue when looking at things for a while.

Ways to relieve eye strain.

1.Adjust the lighting.

Reading in low light won't hurt your eyes, but if the light doesn't provide enough contrast between light and dark, it will make your eyes tired. Soft lighting that provides chiaroscuro should be used, and electric lamps that reflect light directly to the human eye should not be used.

2.Take well-timed breaks.

If you work in front of the computer for 6-8 hours straight, you should take a break every 2-3 hours. Grab a cup of coffee, go to the bathroom, or just take your eyes off the computer for 10-15 minutes.

3.Adjust the brightness of your computer screen.

The fonts and numbers on your computer screen are like little light bulbs that shoot light directly into your eyes. Therefore, you need to reduce the brightness of the screen and adjust the contrast between light and dark to make the font clear.

4.Give your eyes a good rest.

The best way to relieve eye fatigue is to rest your eyes, which is easier than you think. You can hit the ** while keeping your eyes closed. If you don't need to read or write anything, you can close your eyes and rest while chatting.

5.Apply a warm compress to the eye area with your hands.

Rub your hands together until they are warm. Then, close your eyes and cover your eye circles with the palms of your hands, without pressing them. Breathe deeply and slowly, and imagine the darkness. Doing this for 20 minutes a day can help reduce eye fatigue.

6.Blink often.

The eyelids are the personal masseur of your eyes. Deliberately blink 300 times a day to help clean the eyes and give them a small massage.

7.Apply tea to the eye area.

Soak the towel in the millet herb tea, lie flat, and apply the warm towel to the eye area for 10-15 minutes. This will make your eyes tired, but be careful not to drain the tea into your eyes. At the same time, let the millet tea cool for a while before dipping it in the towel.

8.Give your eyes nutrients in a timely manner.

Generally, we use Leyan vision nutrients to supplement the comprehensive nutrition of the eyes, so that the eyes are fully nourished, so that the eye fatigue will be healthier!

What causes eye strain

Our eyes are like machines, and it is easy to cause fatigue in our eyes if we use them for a long time without rest, which is what we call vision fatigue, which is mainly caused by excessive use of eyes and insufficient supply of eyes for a long time. Let's talk about the causes of eye strain.

Causes of eye strain

Use your eyes for a long time without rest.

When our eyes are poor and face the computer or books for a long time, it is very leaky and easy to cause visual fatigue in our eyes, and when our eyes are tired of vision, it is easy to cause insufficient tears secreted by our tear glands, which will make my eyes dry and even myopia. So we have to improve this habit and way of using our eyes.

When we use our eyes for a long time, we should learn to let our eyes get a good rest, through a distance, ** green plants and other methods can well relieve the muscle fatigue of our eyes, so that our eyes can get a good rest, improve the symptoms of eye congestion.

Do not take protective measures in bright light.

The summer sun has strong ultraviolet rays, and when we are doing outdoor activities, it is easy to cause our eyes to be burned under the strong sunlight, which not only easily leads to our lack of visual fatigue, but also makes us prone to eye diseases.

Through sunscreen, sunglasses and other measures can effectively prevent the impact of ultraviolet rays on the eyes, and it is better not to go out if the sun is too strong to avoid eye burns. In addition, spending a long time in the sun is not good for our health, and it may cause us to suffer from heat stroke.

It is most likely to cause eye strain. Farsightedness, myopia, astigmatism, presbyopia, excessive eyes, etc.

Eye fatigue is a common ophthalmic disease, which causes dry eyes, astringent eyes, soreness and swelling of eyes, blurred vision and even vision loss, which directly affects people's work and life. Eye fatigue occurs mainly in the near eye and the symptoms are varied.

Extended Materials. Because the hyperopic eye often overuses accommodation in near work than the emmetropic eye, coupled with the imbalance between the convergence and accommodation, it often feels fatigue when working or studying at close range, and symptoms such as eye pain, forehead swelling, drowsiness, and lack of concentration may occur. The distance to the near point is normal at the beginning of reading, but the distance gradually becomes longer and accompanied by eye strain, and the symptoms are relieved with a little rest.

It is also often complicated by systemic symptoms, such as shoulder pain, insomnia, memory loss, etc.

If the reading time is too long, or the time of working in close proximity is too long, the ciliary muscle can be spasmodic due to overuse of accommodation, resulting in so-called pseudomyopia (accommodative spasticity), which is common in adolescents. This type of pseudomyopia often has significant symptoms of eye strain. Some people with myopia or astigmatism who wear glasses with a large prescription are also prone to eye strain.

When the accommodation is insufficient or the adjustment is weak, the near point distance shifts to the distance, and if you barely do the close distance, it will inevitably overuse the accommodation and cause eye fatigue. Some local or systemic diseases such as glaucoma, eye contusion, anemia, endocrine disorders, acute infectious diseases, etc., can cause eye fatigue symptoms caused by regulatory weakness.

When the myopic eye does not wear glasses, due to the close distance between the near point, no or little adjustment is required, so the balance between the convergence and accommodation is disrupted, and the convergence is more than the accommodation, and eye fatigue can also occur. Work or reading can not last, easy to skip, flash, can not engage in stereoscopic work, in addition to conjunctival hyperemia. Once the appropriate glasses are fit, the symptoms can be reduced or disappear.

Long-term wearing of overcorrected farsighted glasses can often lead to insufficient radiance function and gradual exotropia.

In addition, hypoplastic vergeotic function, post-illness failure, endocrine disorders, neurasthenia, amblyopia, and presbyopia can also cause eye fatigue.

1. Excessive use of eyes, such as looking at the phone for a long time.

2. When working, because of staring at the computer for a long time, the frequency of blinking decreases, resulting in eye fatigue.

3. Reading in a poorly lit environment can easily lead to eye fatigue.

4. How far away can you usually look at, or do health exercises, eye massager massage, and relieve.

In this case, it is generally considered to be caused by too tired eyes, and it is necessary to pay attention to:

1. Pay attention to the time you spend with your eyes.

Children's eye development is not perfect, the ability to work is low, every time you read or write for an hour, you should let the child go to outdoor activities, do games, look into the distance, or observe the flowers and trees, so that the tense eye muscles are relaxed, eliminate fatigue. In addition, it is necessary to make the child's life regular, have enough sleep, and let the eyes get enough rest.

2. Pay attention to the light of your eyes.

Do not allow your child to read or write in dark light or sunlight. If a 25-watt light bulb is used indoors at night, the distance between the book and the bulb should be within 1 meter. If you use a 60-watt bulb on a stool, the distance between the book and the bulb should be 1 2 meters.

Cloudy days, dusk, weak light in the moonlight, and strong light in the sun are not suitable for reading and writing. When watching TV, it is necessary to maintain a suitable distance, which should generally be 5 7 times the diagonal length of the phosphor screen. The time to watch TV should not exceed 2 hours at a time.

3. Pay attention to eye exercise.

Physical exercise can enhance blood circulation and metabolism, supply more nutrients to the eyes, and enhance the resistance of the eyes, which is an indirect exercise for the eyes. The direct exercise is eye exercises, which is based on the massage, massage, acupuncture and acupuncture acupuncture points of Chinese medicine, combined with jujube Kuanhui medical sports, which is a scientific method to protect eyesight. Parents should learn the basic knowledge of eye exercises, give specific guidance and often urge their children to do eye exercises, and persevere.

4. Pay attention to eye nutrition.

In order to protect children's eyes, children can eat more carrots, animal liver, lean meat, to supplement vitamin A, or regularly supplement the comprehensive nutrition of the eyes with Leyan vision nutrients, and at the same time, it is also necessary to appropriately consume millet, tofu, animal liver and other supplements of vitamin B2, so as to avoid night blindness, corneal malacia, red eyes, dry itching and other symptoms. Eating too much sugar will harm your child's eyesight, so your child's sugar intake should be controlled.

5. Pay attention to regular inspections.

Regular check-ups are due to the fact that children's eye structure, binocular visual function, and intelligence are still in the process of continuous development after birth, and the content of the examination is different at different ages. The usual age of ophthalmologic examination is generally 2-7 days after birth, 42 days after birth, 3 months, 6 months, and 1 year of age, and then once a year. In this way, the problem can be detected early and corrected early, instead of waiting until the vision has deteriorated and there is a vision problem before going for a check-up.
