What kind of light is harmful to human eyes, yellow light or white light

What kind of light is harmful to eyesight?

You may have this experience: reading under the light at night is more tiring than reading under the natural light during the day, and it is easy to have fatigue symptoms such as sore eyes, tearing or blurred vision, double vision, and even headache, headache, etc., which seriously affects one's health, especially the health of the eyes! Because the quality of ordinary lighting is not as good as natural light. Why?

Ordinary, the average person only pay attention to the brightness of the light, thought the brightness is enough, on the eyes is good. This idea is unscientific and incomplete. Judgment of the quality of lighting: In addition to the appropriate brightness, the stability of its lighting, uniformity, continuity, light color comfort is very important. Unfortunately, many manufacturers specializing in the production of desk lamps, the above issues also do not pay enough attention to its products only in the shape, color changes, many people for years in the undesirable light to read, study, to the eyes of the health of the eyes to produce a serious harm:

1, strobe damage: generally we use incandescent bulbs, fluorescent lamps, halogen quartz lamps are directly to the 220V, 50Hz alternating current work! Due to the size of the alternating current voltage and current changes 100 times per second, resulting in the lights flicker 100 times, scientifically called "strobe". Although this rapid flicker of the human eye can not be directly distinguished, but this flicker makes the light discontinuous, the human visual nerve stimulated by rapid changes in the light, easy to fatigue, over time will constitute damage to the eyes. Ordinary dimmable table lamps, this flicker is more intense, the human eye damage is also greater.

2, light color damage: ordinary light bulbs light color reddish, feel not bright enough, so that people can not help but close to the book, easy to make the eye ciliary muscle spasm and trigger myopia.

3, shadow and glare damage: due to the relatively small size of the traditional light bulb, light-emitting points concentrated, easy to produce shadow interference; poorly designed lamps and lanterns will also produce direct interference with the human eye - glare, direct stimulation of the human eye.

4, uneven light damage: traditional light source light due to its structure determines the brightness of the irradiated desktop is not uniform, the gap between the strength of a large, often close to the desktop lamp is around the brightness of a few times or even dozens of times, so that people in the reading of the pupils need to be constantly adjusted to adapt to the different intensity of the light fatigue is very easy to produce.

5, bee sound and electromagnetic radiation damage: with fluorescent tubes of desk lamps, the use of iron letter ballasts, often produce a "buzz" sound; or ordinary electronic ballasts are often accompanied by serious electromagnetic radiation and electromagnetic interference, so that human health is affected, but also around the other home appliances can not work properly.

How does BOSHI Table Lamp protect your eyesight?

First of all, Balas adopts a number of international latest scientific and technological achievements to change the current into the lamp into a smooth direct current, and then through the DC/AC inverter to supply the lamp, so that the lamp emits an extremely smooth white light with stable brightness, eliminating the alternating current strobe. It also eliminates the stimulation of human eyes caused by the rapid change of light intensity of general desk lamps, and greatly improves the quality of lighting, and its luminous smooth, continuous, soft, natural, very close to natural light. Prolonged use of the eyes is not easy to fatigue, so that people relax, really protect the eyesight.

Secondly, the Balas lamp adopts tri-color fluorescent tubes, with good light color and realistic color of the illuminated surface. Its larger light-emitting surface, significantly improving the ordinary incandescent desk lamps, quartz halogen desk lamps due to the light-emitting point of concentration and can not be overcome by the shadow interference, writing behind the tip of the pen shadow is extremely small. Very suitable for writing. And the use of CAD design of the lampshade reflective parameters, so that the brightness of the irradiated surface uniformity is good, in favor of the human eye comfortable reading.

Once again, the electronic ballast of Balas desk lamp has a number of technologically advanced technical measures such as anti-lightning strike, anti-electromagnetic interference and anti-electromagnetic radiation, and automatic protection of abnormal state, which is practical, safe and reliable. The touch switch (part of the model) which is made by the integrated circuit of Motorola Company of the United States is elegant, precious and luxurious, allowing you to fully appreciate the charm of science and technology.

At the same time, the Balas desk lamp, that is, open that is bright, never half a bit of noise. Energy saving, with the same brightness than incandescent lamps, with five years only need to pay a year of electricity, the use of economic.

Balas Bo vision of the company's strong technical services to provide users with excellent after-sales service, all products have a warranty certificate to ensure that users have no worries.

Eye care tips:

Balas Boshi lighting engineers to remind the majority of users should be scientific eye care:

1, the use of desk lamps, lamps should be adjusted to the angle, so that the light can not be directed to the eyes, so as not to produce direct glare.

2, the height of the lampshade should be put higher, so that the desktop light uniformity, to avoid the human eye reading, the pupil constantly adjusted to fatigue. At the same time, it can also reduce the desktop, paper surface reflection stimulation.

3, just turn on the lights, fluorescent tubes have not been stabilized, the light intensity is weak, one or two minutes before entering a stable light-emitting state, so you should avoid just turn on the lights immediately study.

4, if used for writing lighting, the lamp can be placed in front of the left, so that the small shadow behind the nib is not easy to detect (for people accustomed to using the right hand), to reduce the shadow interference.

5, it is best to have a top light at the same time, so that the surrounding environment and the desktop main irradiation surface of the brightness difference is reduced, so that the eyes are easy to adapt to, comfortable vision.
