What kind of damage can children cause to their eyes when they use table lamps?

It can cause serious damage, which can lead to worse vision, possible blindness, eye exposure to bright light, and eventually eye fatigue, which can also damage the retina.

It can cause myopia, it can also cause eye bias, it can also cause glaucoma, it can cause farsightedness, and it can also cause vision loss.

Usually a desk lamp is not harmful to the eyes, but reading in too strong and dim light can be harmful to the eyes. Therefore, the table lamp should be placed in front of the left side of the desk so that the right hand does not block the light; It is best to choose a table lamp style that does not directly irradiate the eyes and is fixed; Table lamps can be used with 40 watt bulbs or 20 watt fluorescent lamps to achieve illumination levels of 400-700 lux.

How to choose a table lamp.

1. Low blue light: Blue light, simply put, is a kind of light that is harmful to people's eyesight, and reading books under the irradiation of blue light for a long time can easily lead to myopia, cataracts, and even blindness in severe cases. Especially for children, this kind of injury is more serious, so it is important to pay attention to this when buying a table lamp.

2. Soft light: In normal daylight, we see daylight, the color temperature is about 5600K, this light is white and high, if you read and study in this light, it is easy to cause visual fatigue. The light of the table lamp should be softer, with a color temperature of about 4000-5000K, which has a protective effect on the eyes.

3. No flicker: Many desk lamps will have the problem of strobe, and the strobe will have a great impact on people's eyesight, and it is easy to cause visual fatigue or dizziness. Therefore, when purchasing on the spot, you can test the strobe by yourself, you can turn on the photo function of the mobile phone, and face the position of the lamp source, if there is a flashing dark line on the mobile phone screen, it means that the lamp has a strobe problem.

4. Lighting range: the so-called lighting range, that is, the area that can be irradiated after the lamp is turned on. At present, the irradiation range of table lamps on the market is about 55 cm, which is enough to meet the normal learning and writing.

You may not be very concerned about the radiation range, but in fact, if the lighting range is relatively small, it is easy for people to have an improper sitting posture, and it is also easy to cause myopia, hunchback and other problems.

C certification: On the table lamp used by students, the state requires that it must pass the 3C certification, so when buying a table lamp, you need to pay attention to whether it is a 3C certified product, so that the quality is more guaranteed.

Problem description: I'm using an orange desk lamp to do my homework right now, I don't know if it's good for my eyes?

Analysis: The appropriate reading lighting light is still better than incandescent lamp, although the orange lamp will not cause great damage to the eyes, but it will have a certain impact on your eyesight, because it is easy to produce visual fatigue.

Moreover, when sitting under the desk lamp, it should be noted that frequent use of the desk lamp may not necessarily cause myopia. This is judged on a case-by-case basis.

First, it depends on whether your posture of using the lamp is correct, it is best to use it on the table, if you lie down, it is easy to cause the angle to be wrong, and affect your eyesight.

Second, it depends on whether your station light source meets the national standard. If it is an inferior product, the light may not be suitable for reading, for example, the light is too low, but usually, it will meet the standard of reading lighting.

Third, if there are certain conditions, it is better to buy an eye protection lamp with quality assurance, but myopia is also related to genetic factors and age.

Hope it helps.

Reading in too strong or dim light is not good for your eyes.

The ideal lighting should look like this:

2) Desk lamp style: It is best to choose a table lamp style that does not directly irradiate the eyes and is fixed.

3) Desk lamp brightness: The table lamp can use a 40 watt bulb or a 20 watt fluorescent lamp to achieve a illumination of 400-700 lux.

4) Reduce light and dark differences: When studying, not only turn on the desk lamp, but also turn on the lights in the room, which can reduce the adverse effects of light and dark on the eyes.

1. From the perspective of electronic appliances:

LED table lamp, because the light source is LED, LED is a DC light-emitting device, theoretically speaking, the light emitted, and our previous generations of light source out of the light is different, the traditional light source including energy-saving lamps, metal halide lamps, incandescent lamps, etc. are AC, will follow the frequency of the input current of the civil power grid, change (China is 220V, 50Hz power grid), so the frequency fluctuation of AC makes the traditional light source appear strobe, long-term work and study under this light source will be harmful to the eyes. If you use a rechargeable battery for a table lamp, the light-emitting panel will not directly see the LED lamp beads, and the one without glare can protect the eyes. The other is the LED table lamp driven by constant current power supply, this kind of product, you don't know how to read it, or find a reputable manufacturer to buy.

Second, from an optical point of view:

When the traditional light source emits light, it will emit red wavelength light waves at the same time, which you can understand as invisible infrared rays, which can cause damage to the eyes with a wavelength of more than 780nm. The LED light source, mainly the blue light slice excitation yellow phosphor, the wavelength of the light is between 380-780nm, there is no ultraviolet and infrared, a good LED light source (note is good, most of the things you usually see in the store outside do not match, at present, the domestic such good ones are exported) The color rendering index is greater than 85 (the higher the color rendering index, the closer to natural light), with a relatively complete spectrum, that is, it also has green light waves, close to natural light, and you also know a lot of times** Myopia is all about looking at green things, because it depends on green light waves to repair the damage to the eyes, at least it will not aggravate myopia.

Your question, to be like this, a real LED table lamp (from the light effect, color rendering index, glare value, illuminance, luminous angle, etc.) is definitely good for the eyes.

If the eye is irradiated, electro-optical ophthalmia may occur. It is recommended that if you are afraid of light, tearing, or have swollen eyes, then there may be a problem, and you should go to the ophthalmology department of the hospital for a slit lamp examination. In general, corneal repair eye ointments, such as Befushu eye gel, plus anti-inflammatory eye ointments, such as ofloxacin eye ointment, can be used.

Table lamps do not have much effect on the human body. However, when the lights are turned off at night, it is extremely harmful to the eyesight. Because, all around is black and the table lamp is very bright, forming a strong contrast, which is very harmful to the eyes.

In the long run, this will have an impact on vision.

LED light is a kind of light-emitting diode, which does not produce heat while emitting light, and generally has no harm to the eyes, but can not be irradiated for a long time, no more than 20 to 30 minutes each time, just close your eyes and rest, otherwise it is easy to damage the retina, and try not to use this lamp at close range.

The brightness of the table lamp has an impact on the eyes.

25 degrees or 40 degrees of incandescent lamp as an eye protection lamp bulb is better, and after using the lamp, you can do eye exercises to relieve the eyes, so that relaxing the eyes is very helpful.

Personally, I think that the LED desk lamp is best not to be used by children, I saw an article on the Internet, and a parent bought a Philips LED desk lamp, but when I went home, I opened the manual and saw that it was not suitable for children. But the outer packaging says that the eye-protecting desk lamp, we ordinary people don't know the insiders, and the personal understanding of the eye-protecting desk lamp is of course to protect everyone's eyes, doesn't it include children? It can be seen that the big brands are written like this, and the small brands are for the sake of interests, of course, they will not be written in the manual.

For the sake of the child's eyes, it is better not to use it, it is better to buy a lamp with a few dozen yuan for the child.

The brightness of the desk lamp must have an impact on the eyes, if it is bright, it will not be able to open it, and if it is weak, it will not be able to see clearly, and it will also reduce people's eyesight, and the most comfortable index of people is 40w, so you should adjust it to 40 watts.

Second, I want to remind that the color of the light is also very effective for the eyes, generally we use white light, but in fact, green is the most comfortable for people's eyes, and red is the most harmful to the eyes.

Generally speaking, this has no effect on eyesight, so it is recommended to choose a non-polarized desk lamp, preferably a daylight-colored desk lamp.

LEDs excite phosphors to emit light through blue light chips. Whereas, blue light has an effect on the retina of the human eye. As long as your eyes don't look directly at the LED desk lamp for a long time, it's not a big problem. The spectral ability of blue light is relatively weak. However, there is a question of biosecurity at stake here.

Can't you see anything during the day? Anyway, you have to use the light when you can't see anything. Harmless, ]

No, just pay attention to the distance from the book].

Most of the white light of LEDs is excited by blue light grains to excite yellow light phosphors to produce a white light spectrum, which is close to the blue light hazards defined by photobiological safety. Although inappropriate blue light wavelengths can cause blue light hazards, according to the non-visual response band to light, the blue light band can increase dopamine secretion during the day, which has a positive impact on physiological arousal, positive mood and endocrine.

Although inappropriate blue light wavelengths can cause blue light hazards, according to the non-visual response band to light, the blue light band can increase dopamine secretion during the day, which has a positive impact on physiological arousal, positive mood and endocrine. Therefore, a high proportion of blue light components or light with high color temperature is required during the day, but at night, considering that the blue light band will interfere with melatonin secretion, it is suitable to use lighting with low color temperature at night. Adjustable LED lighting with high and low color temperature can be used according to different lighting needs during the day and night, and has gradually become a new choice for healthy lighting.

It is recommended to wear wet room glasses with blue light protection to prevent dry eyes and prevent myopia.

At present, the most common table lamps on the market are LED lamps, LED is light emitting diode, LED lighting is also known as solid-state lighting, as the third generation of lighting technology after incandescent lamps and fluorescent lamps, it has the characteristics of energy saving, environmental protection, safety and reliability, and the solid-state light source is a new light source with great potential to replace traditional lighting appliances in the next ten years that is optimistic about the industry.

The main advantages of LED are: 1The light source has good directionality, lighting on demand, and is better as an emergency desk lamp; 2.

Sufficient illumination to meet your general lighting needs; 3.DC power supply, well-made LED lamp has no strobe hazard and no electromagnetic radiation; 4.Green environmental protection, high efficiency and energy saving; 5.

Solid light source, resistant to mechanical vibration; 6.No ultraviolet rays, no infrared rays; The small lamp beads have a long life.

Darren LED Eye Protection Table Lamp helps to care for the eyes and reduce eye fatigue. Darren eye protection table lamp adopts imported three-star lamp beads, bright and comfortable, high color rendering, restore the real color, the current of the lamp beads is stable, no strobe hazards, certified by authoritative institutions, no blue light hazards, and healthier eyes

Table lamps include incandescent lamps, halogen lamps, energy-saving lamps, LED lamps, etc., LED lamps are more energy-saving, and now eye-protecting desk lamps are basically LED lamps. Buying an eye-protecting table lamp can play a role in protecting your eyes. Last time, I bought a multi-cow N1 eye protection table lamp for my daughter, the light area is particularly large, and the whole desktop can be illuminated.

The least harmful to the eyes of the lamp should be the incandescent bulb.

No matter what kind of desk lamp it is, it only has eye protection function for a short time, and it is also harmful for a long time. Pay attention to rest, the combination of work and rest is the key.

Hello, whether a table lamp is healthy and eye protection is mainly judged from three aspects, one is no flicker; Second, the light is suitable; The third is no radiation ultraviolet rays.

Desk lamps with direct current are preferred, because traditional 220V alternating current will leave 50 Hz of current fluctuation, which will cause the light to flicker. Strobe can easily cause eye strain, decreased vision, and deepened myopia. There is also a light source that prefers yellow light, which is a warm color, warm and comfortable, stable and not dazzling.

Then there is to see if there is radiation ultraviolet rays.

LED lights cannot be used for close-up reading and writing work, because the blue light, a short-wave, high-energy light source emitted by LED lights, can directly penetrate the cornea and lens, and can reach the macular area, causing burns to the retina of the human eye.

Vision housekeeper Kang Luyuan 24V DC incandescent lamp reading and writing desk lamp is good, can be used as a reading and writing desk lamp for children, will not hurt the eyes, it is designed and manufactured in strict accordance with the national reading and writing desk lamp standard, with Chinese patents, Dr. research and development, no radiation, 0 strobe, no blue light, color rendering index up to 100RA, color temperature 2800K, the most comfortable, stable, equivalent to about 40 minutes after sunrise of the sun, the eyes are easy to accept, care for children's eyes.

I hope it can help you and be adopted by you, thank you!

When it comes to lights, the most familiar ones are probably strobe and blue light. Generally, if you choose a regular brand, you don't have to worry too much about these two issues, and they can basically meet the requirements. A good light, in addition to strobe and blue light, is the most important.

Illumination and color temperature, it is recommended to choose in fact, eye protection lamps and ordinary lamps are limited to eye damage, myopia is mainly caused by too long a time to see close, eyes and eyes are too close to the object of gaze. Therefore, we should look more far and look less at mobile phone electronic products.

Choosing a desk lamp for students to learn, I think the main thing to look at is the brightness of the lamp, neither. You can choose too bright or too dark, the light is natural and harmonious. To prevent myopia in children, the correct choice of table lamps is one thing, and it is also important to develop good eye habits.

The lamps that are really good for the eyes are the ordinary incandescent bulbs, the ancient light bulbs. It belongs to the thermal light source, and its disadvantages. It costs electricity, but you should know how to choose between a child's vision problem and a few kilowatt-hours of electricity.

In fact, judging from the current situation, choose a big brand of eye-care desk lamp. There must be nothing wrong, for example, Philips Opple and other professional lighting companies, the products they make must also be well-known, of course, now the more popular brands, there are small additions, in the protection of children's eyes, I still recommend listening to the opinions of some professionals, from a scientific point of view to protect better. Just by a lamp.

It's just going to make a difference.

When choosing a table lamp, look at the light source first, which is very important, because. With the popularization of mobile phones and computers, modern people have a huge amount of eyes, if you choose ordinary light sources or LED light sources, there will be a risk of glare, ghosting and blue light, which is easy to cause retinal damage. It is also a very smart desk lamp, which can remind my baby of the sitting posture and rest with his eyes by voice, etc., and there is also a **care function, that is, you can see the child's learning in the room by turning on the mobile phone in the living room, and you don't have to go over to disturb his learning, which is very worry-free!
