How about a good vision eye protection lamp It s easy to use

Hello, this usually brings glasses yes, to see things to see the clear, but once you take it down and return to the usual appearance, it will only cause dependence, if you want to alleviate myopia or reduce the degree, this is unlikely, at present, science and technology for myopia, there is no particularly good way. At the same time, Good Vision Eye Protection Lamp and Good Vision Eye Patch are not products of the same company, they are essentially different, please pay more attention to observe and don't be deceived!

This lamp is quite poor, it took a year to burn it by itself, don't go to the official *** to buy, if you repair it, you have to pay the round-trip freight, and you have to add maintenance fees, which is more expensive than you buy a table lamp, as a consumer, you can only admit it!!

What I bought is this sliding dimming 99 yuan that, the company name is Shenzhen Tongjian Optoelectronics, it has been broken for more than a year, it is put there and it is useless, and it is broken. Contact with the after-sales service, and he doesn't ask any questions and says that a maintenance ** makes you difficult to retreat, and the return postage has to be paid by yourself, which means: don't repair it, buy a new one.

Even if I buy them again, I won't buy them again.

It's soft and nice.

Tmall official *** bought a good vision desk lamp, 9 months the light went out, occasionally used once, I asked me to send it to them at my own freight, they took it for testing. Oh, a light bulb costs 10 yuan, I spent 10 yuan postage to send it, I have nothing to do. What the?

More than 10 bucks for a light bulb? So how did such an expensive light bulb go out in 9 months? More than 15 days, Tmall can not apply for after-sales, can not be reviewed, can not appeal, good vision, what three-year warranty is your postage.

Anyway, you can't do anything to him, consider yourself unlucky. Good Vision's first consumption was also my last consumption.

There are three ways to choose an eye protection lamp. First, it depends on the appearance: this appearance refers to the light of the eye protection lamp, and the light of the qualified eye protection lamp generally does not have any strobe, is relatively soft, not dazzling, and the brightness of the light is relatively uniform.

Second, it is necessary to look at the certificates, the product qualification certificate of the eye protection lamp, the product safety certification certificate and other documents should be complete, and there should be sufficient spare parts such as lamps to ensure the needs of consumers from time to time. Third, we should look at after-sales service: the use and maintenance methods of eye protection lamps are particularly important.

I bought it for my daughter in Ingres, and it feels very good.

I haven't used this brand, I don't know, I bought it for my daughter is Angels, and it feels very good.

Good eyesight, eye protection, table lamp is very good.

The eyesight protection light beads are evenly distributed, achieving the effect of no blind spots, no shadows, and uniform light, which effectively helps to alleviate visual fatigue, and the visual fatigue of reading and writing is not fatigued, and the eyes are more comfortable, effectively protecting the development of children's eyes, protecting eyesight and health. So it's good to have good eyesight and eye protection desk lamps.

The features of the eye-friendly table lamp are as follows:

1. The light is very soft.

The first feature of the eye-protecting table lamp is that the light is bright but soft. Judging from the color temperature data of the light, the color temperature of our common fluorescent lamp is 5600K, which is about the same as the noon sun, but for reading Xiaochun socks and writing, such light is white and bright.

2. Low blue light.

Blue light is a high-energy visible light that can penetrate the cornea and lens, thereby causing damage to the retina, resulting in eye diseases such as myopia, cataracts, and computer syndrome, which are now common. Eye-protecting table lamps can filter harmful blue light, thereby reducing its damage to people's eyes.

3. Large lighting range.

The high degree of science and technology is higher than that of the human eye, and the range of lighting is larger. If the light of the desk lamp is too concentrated, in a dark environment, the light input of the human eye will be high, and the eyes will be vulnerable to damage. But the light is scattered, the illumination range is larger, and the human eye absorbs the incoming light based on the average brightness of the surroundings.

At this time, the light absorbed will be smaller, and the light height of the table lamp will be higher than that of the eye.

This is because, once the light source of the table lamp is lower than the light source of the human eye, the person's vision will first accept the darkness, and then accept the irradiated area of the table lamp, causing great damage to the eyes. <>

Hello, the good vision eye protection lamp uses DC ballast, so that the DC technology does not have any fluctuations, and avoids the problems of electromagnetic radiation and electromagnetic pollution caused by high-frequency electronic failure or high-frequency ballasted fluorescent lamps. Its light beads are evenly distributed to achieve the effect of no blind spots, no shadows and uniform light, which can effectively help users alleviate visual fatigue, make their eyes more comfortable when reading and writing, and can well protect the development of children's eyes.

About strobe: the strobe problem is basically now fooling people, some say that there is no strobe is really no technology to show off, the problem of strobe only exists in the inductive ballast lamps, what is the inductance ballast lamps, to tell you, now basically can't see, if you are 70 years old, you may have the impression, is the kind of light that flashes first and then can be lit normally, generally when the lights are turned on, there will be a buzzing sound, and the strobe phenomenon only exists on this fluorescent lamp.

At present, it is basically a lamp that uses electronic rectification, 10W theoretical flashes per second, think about it is 100,000 times a second, if this kind of lamp can make people feel the strobe, then you can congratulate him, it is no longer a human eye, it is a god eye, this kind of eye can see the bullet fly without eye protection lamp. If you don't feel the strobe, you won't have fatigue, and if you don't feel it, there won't be harm.

If an eye protection lamp manufacturer still uses no flicker to fool consumers, it is really out.

About color temperature: most of the lamps on the market are 6400K and 2700K, 6400K is white light, and it feels white and blue. 2700k is yellow, and the yellow one is a little red.

Eye protection lamps generally use a color temperature of about 4500K to 5000K, but it is difficult to distinguish without reference. However, if you combine the above two color temperature references, it can be judged that the deviation of the international color temperature can have a margin of 500k, that is to say, 4500k is also OK, and 5500 is also OK. Anything beyond that value is fine.

At present, some lamps on the market are halogen powder, not pure trichromatic phosphor, and it is not easy to distinguish.

Eye protection lamp is a functional judgment, the final effect is determined by the eye, although the country has a product standard for the lamp, but there is no unified standard for the "eye protection lamp". SoDo eye protection lamps work？How does an eye protection lamp work?

Below we will answer them one by one, hoping to be able to help you.

Does the eye protection lamp have a positive rock fiber?

Many people will still grow their eyesight after using eye protection lamps, which makes many people wonder whether eye protection lamps are useful, in fact, eye protection lamps only protect their eyes in the light, and do not have the effect of protecting eyesight, and the most effective example of protecting eyes is to strengthen the attention to eye protection, do not use your eyes excessively, and do more outdoor activities at the same time.

How the eye protection lamp works:

Increase the low flicker to high flicker, use frequency conversion electronic ballast, increase the electrical frequency from 50Hz to 5500Hz to reduce flicker, use trichromatic phosphor, reduce the glare effect, make the light soft and not dazzling, so that the human eye can not feel the discomfort of stroboscopy, so as to reduce visual fatigue. The less strobes, the better the lighting. Very few turn alternating current into direct current, use DC ballast, use direct current lighting, it will not flash at all, achieve real flicker-free, and the light is close to natural light when used, very bright, but not dazzling at all, very soft, greatly alleviate visual fatigue.

And compared with other eye protection lamps, there is no electromagnetic radiation. The related technology of DC eye protection lamp has been awarded the invention patent certification by the State Intellectual Property Office.

The above is the eye protection light brought to you, is it useful? The whole story of how the eye protection lamp works.

Yes, in short, it provides a comfortable lighting environment. A good table lamp is mainly determined by illumination, blue light, strobe, CRI and color temperature, etc., by providing a very comfortable lighting environment to alleviate long-term eye fatigue, so it is still effective.

He can only say that it played a certain role, but did it work well? This is still different from person to person, I feel that it can only play a small role, not a particularly good role, as much as possible. At night, he can only say that it plays a certain role, but is the effect good?

This is still different from person to person, I feel that it can only play a little role, not a particularly good role, try to time, or don't use these electronic products at night.

In fact, the eye protection lamp still has a certain effect, and the eye protection lamp actually still has a certain effect. In the case of eye protection lamps, eye protection lamps are still very good for eye protection.

About this eye protection lamp, this is a commodity performance, if the real performance is better, it has a protective effect on this eye.

Based on the situation you described, your question is to ask about the property, etc., is it really effective? This must have an effect, that is to say, the eye protection lamp designed by the manufacturer according to the human eye, for example, the lamp in the past, she is always flashing, but the current lamp rarely flashes, it can be said that this is definitely good for the eyes.

Generally, the flashing frequency of the lamp is 50Hz, which has an obvious strobe effect. Eye protection lamps generally use DC or higher frequency alternating current, which has a certain effect on reducing eye fatigue. But don't rely too much on it.
