There are often all kinds of noise in life, and noise can have a great impact on people, affecting people's hearing, talking and thinking. But what many people don't know is that noise can also affect people's eyesight, that is, the eyes are also afraid of "noise". The eyes are used to see things, and they are greatly affected by light, and sound belongs to sound, so why does sound affect the eyes?
This is mainly due to the subtle inner "connection" between the eyes and the ears.
When noise affects the auditory organs, it also "ripples" to the visual organs under the action of the nervous system, thus reducing the sensitivity of the human eye to light.
Studies have shown that when the volume reaches 90 decibels, the sensitivity of rods in the retina to distinguish light will be reduced, thereby prolonging the reaction time of people to recognize low light; When the noise reaches 95 decibels, the person's pupils will dilate; When the noise reaches 115 decibels, the adaptability of the human eye to light is reduced by 20%. Therefore, noise will affect the eyes to a certain extent.
In addition, if the eyes are affected by noise for a long time, problems such as eye fatigue, eye pain, blurred vision, and tearing will occur. This is because noise interferes with the body's absorption and metabolism of vitamin A, resulting in an imbalance in ocular metabolism and reducing the sensitivity of the eyes to light, which in turn causes many uncomfortable symptoms in the eyes and even affects vision.
Therefore, when we often work in a noisy environment, or are often exposed to noise in our lives, we should eat more fresh fruits and vegetables and supplement vitamins as compensation for abnormal consumption, maintain the normal function of the eyes, and prevent and reduce the harm caused by noise to vision.

Noise hazards to health With the improvement of people's material living standards, all kinds of household appliances have entered thousands of households, and people enjoy these modern civilizations at the same time, but also bring some harm to the human body, household noise is one of them. It has been determined that the noise generated by televisions and tape recorders can reach 60 to 80 decibels, washing machines 42 to 70 decibels, and refrigerators 32 to 50 decibels. According to the relevant national standards, the environmental noise in residential areas should not exceed 50 decibels during the day and 45 decibels at night.
Noise can be harmful to the human body, especially to children. According to statistics, if children live in a noise environment above 80 decibels, the number of deaf and mute people can reach 50%. Children who are often exposed to noise often have eye pain, dizziness, vision loss, etc., and can also cause neurasthenic symptoms such as dizziness, headache, insomnia, dreaminess, fatigue and memory loss, and lack of concentration.
Noise can also affect normal digestive function, reduce the secretion of saliva and gastric juice, and drop gastric acid, which can cause digestive tract diseases. Therefore, noise is the enemy that affects children's intellectual and physical development. Surveys and studies have shown that the intellectual development of children living in noisy environments is about 20% lower than that of children living in quiet environments.
Japanese scientists have examined more than 1,000 newborn babies and found that babies living in noisy environments generally weigh less than babies living in quiet environments. In order to eliminate and reduce the harm of noise to children's health, the volume and start-up time of household appliances should be strictly controlled; Household appliances should not be placed in the bedroom and should not be turned on at the same time; purchase high-quality, low-noise household appliances; If conditions permit, sound insulation and sound absorption facilities can be installed to reduce the harm of noise. Secondly, eat more foods high in amino acids and vitamins, such as animal liver, legumes, and fresh vegetables.
The third is to plant flowers and trees around the courtyard and living room, which can not only green and purify the environment, but also absorb and evacuate part of the noise. Fourth, to give children a harmonious and peaceful family environment, we should pay attention to the volume of household appliances should not be too loud, and properly control the entertainment time, so as to be conducive to the healthy growth of children. In view of the growing noise problem that plagues people, the German Environmental Protection Association requires that effective measures such as noise reduction legislation be taken as soon as possible to ensure a quiet living environment.
Schaller, president of the German Transport Club, suggested that a 30-kilometer speed limit should be imposed on all vehicles in the city, 100 kilometers on highways close to living areas, and that all heavy trucks should be prohibited from passing in urban areas. In addition, motorcycles, airplanes, and railways are no exception and need to be limited in order to effectively control noise.

Medical studies have shown that noise makes people's eyes less sensitive to light. An experiment showed that when the intensity of noise reached 90 decibels, the sensitivity of rods in the retina to distinguish light brightness began to decrease, and the time to recognize low light response was also prolonged. When the noise rises to 95 decibels, 40 people will have dilated pupils; When the noise reaches 120 decibels, the eye's adaptability to light brightness decreases by 20 dB.
Noise also has a huge negative impact on the stability of a person's visual clarity, for example, when the noise is at 70 decibels, it takes about 20 minutes for the visual clarity to return to a stable state;When the noise rises to 85 decibels, it takes more than an hour.
In addition, noise can cause the eye to fail to respond to the symmetrical balance of objects. This is mainly due to the fact that noise has a huge inhibitory effect on the human nervous system, which can occur if a person is exposed to a noisy environment for a long time. For example, bus attendants, drivers, and lathe workers are generally slower than ordinary people to react to the symmetry and balance of objects, which is caused by working in a noisy environment for a long time.
Noise can also cause abnormal changes in people's color vision and color vision. When 80 workers who worked in a noisy environment for a long time were examined, it was found that the probability of red, green, and white vision narrowing among them was as high as 80, which was much higher than the normal population.
The effects of noise on the eyes are not limited to the figures derived from these scientific studies, in fact, most people have experienced it directly in daily life, for example, when we are shopping in a quiet, bright store, we tend to be happy and calm, and we will choose our products very carefully, and finally buy the products we want. If you are in a store with a high decibel trend, you will not only be irritable, but also feel dazzled, and the final purchase is often unsatisfactory, the main reason for this is the impact of noise on your eyesight.

Hello!The effect of noise on the eyes mainly interferes with the absorption and metabolism of the human body for vitamin A, resulting in an imbalance in the metabolism of the eye, reducing the sensitivity of the eye to brightness, and then causing many symptoms of the eye and even affecting vision.
-
Yes, because noise can affect a person's sleep, causing a person to not sleep properly for a long time.
The researchers found that when the noise intensity reached 90 decibels, there were nearly 40 people.
Pupil dilation and blurred vision are present;When the noise reaches 115 decibels, almost all.
The adaptability of the human eye to light and brightness is reduced to varying degrees. Long-term exposure to noise.
People in the environment are prone to eye damage such as eye fatigue, dizziness, eye pain, and visual tears.
Phenomenon. At the same time, noise can also change a person's color vision. Such as Suda Mining in the United States.
He Machinery Company has conducted a vision test on 46 employees who have worked in a noise environment of about 90 decibels for five years, and found that 94 of them appeared to varying degrees.
Decreased visual acuity in both eyes, eye pain, dizziness, photophobia, tearing, blurred vision, and color discrimination.
ophthalmic pathological changes such as hypotrophy.
What is the mechanism of noise damage to vision? Studies have shown that noise interferes with the body.
Sexual hazards affect the body's absorption of vitamins, mainly those related to vision.
Absorption and utilization of biogen A. Therefore, experts recommend that work in a noisy environment is often used.
or people who are exposed to more noise in their lives should add some vitamin-rich foods as appropriate.
Things like vegetables and fruits.

In order to reduce the impact of noise on health (hearing and vision), people have developed active noise-cancelling headphones, which can cancel out ambient noise by more than 90%. There is a short film on noise on American television, which shows the effects of noise on people's health.
-
Yes (v) Hmm.
Experiments have shown that when the noise intensity reaches 90 decibels, the sensitivity of human visual cells decreases, and the reaction time to recognize low light is prolonged. When the noise reaches 115 decibels, most people's eyeballs have varying degrees of adaptation to light.

Some people may think that noise can damage our eyesight is alarmist, and think that noise will only affect our hearing, how can it affect our vision? Besides, it is our ears that hear noise, not our eyes, so what effect does noise have on our eyes? In fact, noise can damage eyesight, and the damage to eyesight is still quite big, people must get out of this misunderstanding, all in all, noise is very harmful.
Noise will damage our eyesight, we will all have this feeling, when we hear a pleasant sound, our mood will be more pleasant, so the things in front of us will be clearer, but when we hear a harsh sound, and it is the kind of sound like a hundred claws scratching the heart, we will be particularly irritable, and then there will be a feeling of dizziness, at this time the sight is also a little blurry, so noise will damage our eyesight, a long time under the noise, not only our vision will be affected, And our mood can also become very bad.
We have the impression that our five senses are all the same, that is, the weakening of one of the organs will affect the sensitivity of the other organ, for example, if the person is blind, then his hearing will be particularly sharp, if he is deaf, then his eyesight will be particularly good, and his vision will be particularly clear. This is what we call sensory compensation, but correspondingly, when we hear noise, our ears are damaged, and our vision is blurred.
Noise will also affect our absorption of vitamin A, and this element is very good for vision, which affects our sensitivity to light, if we are in a noisy environment for a long time, our light perception will become weaker, and for a long time, our vision will deteriorate, so noise will damage vision.
Regardless of whether it is damaged or not, we should stay away from the noise environment, noise is not any good, just stay away!
-
Noise does not damage eyesight because it affects a person's hearing, and it is even possible to be deaf.
-
Noise does not impair vision, on the contrary, it can damage hearing and affect hearing.
-
Yes, it also has a certain effect, noise can not only damage our ears, but also our eyesight, so don't live in a noisy environment.
-
The impact of noise on hearing is very large, especially some noise that exceeds a certain decibels, and the impact on the eardrum is very large, so in such an environment, earplugs should be worn.
-
Some influences are related to the decibel level of noise, and the louder the noise, the more serious the impact. Try not to let him exceed the standard of the general environment, basically nothing.
-
If the noise is loud, it actually has a big impact on hearing. In particular, loud noise is easy to damage hearing, and it is easy to cause hearing loss if you are exposed to a loud noise environment all the time, so try to avoid noisy environments! Good luck.

The size of the ** distribution of noise has a certain impact on human tinnitus, and the structure of the human body of the old god has a certain relationship with the eyes and eyes. So while noise affects the ears, it also affects other aspects, including the eyes, which means that it affects vision.
-
Noise can damage hearing, and orange grinding can also damage vision. This damage occurs mainly because of the subtle internal "connection" between the ear and the eye. When noise acts on the auditory organs, it will "spread" to the visual organs through the action of the nervous system, weakening people's vision and reducing their sensitivity to light.
Sleeping more is not necessarily a good thing, eat more food that manages the eyes, often look at green things, pay attention to eye hygiene, as long as the eyesight is no longer **.
Frequent removal of glasses has a great impact on vision, because the lens of our eyes, as you frequently take off your glasses, it will change back and forth, which is easy to make the eyes tired. If you have to wear glasses, it's best to wear them all the time, but be sure to pay attention to the shocking news, read for a long time, and give your eyes a time to relax later, at this time you have to take off your glasses and see the scenery from afar. >>>More
So,in the face of such a large myopic population,how can we protect our eyes well?First of all,we need to know what behaviors are very harmful to visi
To put it simply, the trace elements that help vision are vitamin A, followed by calcium, vitamin B and vitamin C. Vitamin A, also known as retinol, plays an important role in the formation of human vision. It is involved in the synthesis of rhodopsin in the retina, and if vitamin A is insufficient, the eye's ability to adapt to dark environments will be reduced, and in severe cases, it may lead to night blindness. >>>More
