Eye lights play is a concept, with longer fatigue
Eye lights do not have “GB”, manufacturers own standards
Yesterday, reporters went to a lighting market to understand the situation of East Zhongshan Road Nanjing, find eye-lamps on the market is really varied, ranging from $ prices $ $ from more than 20 to more than 300. A salesperson told reporters, many types of eye lights currently on the market, better eye light you can adjust lighting to suit your needs.
Sales people said take a higher-priced eye lights on presentation to reporters. “Ordinary table lamp light emitted by that of the more glaring light, so in this lamp takes too long to learn, on human vision has a lot of injuries, eye of light emitted light is soft, natural light, brightness and relatively stable, nor Flash, so you can effectively protect your eyesight. “When reporters asked what standards when judging eye lights, the sales person told a press conference, eye the light is a standard for all manufacturers, there is no unified national Executive standard.
Eye lights of so-called “no strobe” is actually a “high frequency flashing”
Press search on the Web for a while, found in many so-called technology, intelligent eye lights advertising, these ads in the eye lights have “radiation-free”, “no strobe”, “no shadows” and “non-glare” effect. One industry source told reporters that the so-called eye lights the main selling point is the “no strobe”, which means that the lamp light stability, not a Flash splash, and it is only relative to the fluorescent lamp. Eye lights in real sense, not high frequency Flash strobes but are high to human eyes don’t feel the speed. It was eye light the characteristic, issued it as more stable and more comfortable compared to the light of fluorescent lamps. “Eye-light is the basic working principle of Flash increased low frequency to high frequency flashing, but as said by high frequency Flash must be advertising strobe-free, long time in this light reading, eye also results in fatigue. ”
“Eye feature” is detected, and normal lights doesn’t make much difference
“Eye-care is a feature of the judgment, the ultimate effect is to decide with the eyes. Countries although the lights are standard, but on the ‘ eye-light ‘ but there is no uniform standard. These so-called eye lamp product performance is an ordinary lamp. When testing, quality inspection departments can only detect it has failed to meet product standards, but on the ‘ eye ‘ this function is unable to determine. “Quality inspection departments concerned in Nanjing told reporters that the eye lights more businesses play a concept, there is no accurate data to support its so-called eye function.
“Using eye-light and ordinary light, no great difference, typically basic energy-saving lamps will be able to meet the daily needs the eyes of the people. “However, for some people questioned whether the eye lights will cause higher brain radiation because of high frequency flashing problem, Nanjing General Hospital of Nanjing military region Director Liu Xinfeng in neurology or query on the eye lights eye function, says it will make much harm. “Exposure to radiation has a lot people now live, the dose of radiation to a certain aggregation effects on the human body, there is no experimental proof eye light strong radiation harm the brain. ”
Vision loss and cannot be “culprit” attributed to the eye lights
Children using the lights do not have color
Eye-light, why do children of myopia has deepened? Is eye-problems with the quality of the light? Wang Yuliang, Director of ophthalmology in hospitals in the province, “said eye lights” can be “eye” and there is no scientific justification. Lead children’s vision problems are many, can not be completely “culprit” comes down to eye-lamps.
Lighting for many parents concerned about quality issues, basic lighting angle for an interpretation of Wang Yuliang. His children the most common desk table lamp lighting categories: incandescent, fluorescent lighting and energy-saving lamp light source. “Incandescent light red, light in the infrared components higher, luminous efficiency is relatively low electrical energy into light sources; fluorescent lamp luminous efficiency than would be 20%, and light flashing high; so from the perspective of photosynthetic efficiency ratio, energy-saving lamps is relatively good. “Mr Wang told reporters, flashing for more than 20 times per second, eyes seem more stable light source. What lights to protect eyes, what kind of light on the eye injury, there is also no clear results.
So what should parents how to properly use the lighting? Director Wang suggested: first, for the children to use lights do not have color. Many families were installed the color of ceiling lights, color of the lamp is not suitable for reading light, depending on the cell to see the red, green and blue color, if you focus on one of the colors in a single light source, for a larger vision of injury. Bathroom lighting is definitely not open, it emits is infrared light, serious damage to eyesight; the second, brightness of the lights fit is very important. “Not too bright, not too dark. ”
Protect your eyes count on what lights do not fly
Special attention should be paid to children towards opportunities
Child matters, but cannot relax! In an interview at the press conference, many parents with this concept, which not only helps children working overtime to brush up on their homework, on the other hand is the best buy eye light, and let the child do on a regular basis “eye exercises” to reach the “rest” effect. But Wang Yuliang believes that eye exercises for each section of the “rules” are theoretically derived, you cannot rely on this to protect the eyes.
“For the light source, and as close to the solar light as possible for eye development. Because our living environment is most often exposed to natural light. “Wang Yuliang, Director said, the entire spectrum of the light from the light source is the closest to natural sunlight. Full-spectrum light source can be referred to as full spectrum light, can have red-orange to green and the Sun Dian seven colors of purple, so you can minimize the damage to the eyes. “Protect your eyes count on what lights do not fly, the most effective is to strengthen attention to the eyes, and at the same time doing outdoor activities. “Wang Yuliang recommends:” parents can put the child’s Desk under the window, provide children with opportunities to view. ”
