Do Led strip light Really affect vision?

Some people say that the light emitted by LEDS is blue, and the spectrum is missing, which affects vision

For LED light damage to the vision of the statement is also more, some say that the use of LED for a long time will be dizzy, uncomfortable, and even damage the vision (this is to refer to the eyes staring at the LED light to see?) ; But also said that because there is no ultraviolet and infrared light in the spectrum, there is no heat, no radiation, will not bring burden to the human eye, long time reading or work will not have eyes pain and swelling phenomenon (this is the use of LED lighting, do not stare at the LED lamp?) .

There are two main pieces of evidence that leds are harmful listed on the Internet, one by experts in Germany (no source or trial data can be found); Two is the baby to see the bath bully lamp blindness, a domestic professor said that the blue light in the bath bully caused. Another example in my life is that my classmate basically lost his eyesight because he stared at the LED flashlight with one eye for a long time, and he could only feel light. According to him, he looked at the LED flashlight for about 5 to 10 minutes.

In addition:

According to the 12th Five-Year Plan of the Ministry of Science and Technology, LEDS should account for 30 percent of the lighting market by 2015, and the National Development and Reform Commission has laid out a roadmap to completely phase out incandescent bulbs by 2016.

A lot of LED spotlights are used in the decoration of euramerican style on the network.

The jury is still out on leds. Although leds look like daylight, their spectral composition is far from that of natural light. We’re testing it with over 60 monkeys, and we’re just getting started, and I can tell you what the results will be.

Ps: In fact, there is no artificial light is harmless to the human eye. It’s been a long time… There were no observable abnormalities in the monkeys’ eyes. Now all kinds of monochromatic light is shining. I forgot to answer this question early. Today I suddenly turned it out. I didn’t expect so many people to care. I graduated normally, and entered the pit after the blog. The monkey finished the first phase of the test (LED irradiation of normal light source), and now I am doing the second phase of the test (test under various abnormal light source environment). In general, qualified leds do not have a significant impact on visual acuity at normal brightness. But leds emit blue light, which can disrupt circadian rhythms.

Actually should say so, all the artificial light, such as improper use will certainly affect vision, specific to the LED lights, is responsible for factory production of products, in the artificial light relative is the highest degree of safety of a batch of, is not responsible for factory production sold by weight or TB 2 piece of wallet mail, to the degree of safety is the lowest in the artificial light. I said look at everyone’s in blue light damage, blue light damage is there must be first, there are a lot of factory laboratory instrument light need aging test, of which most blue 450 nm, before my wife doesn’t myopia, eyesight is very good, but occasionally into the lab to see the aging situation, 2 years time, eyes began to rise the pain and see the wind tears. As for some other friends, customers bought some cheap goods with high color temperature, after they went home to install them, the most serious I have seen a family of three dare not turn on the light at night, because as long as the light is turned on, the whole family are dizzy and eyes hurt. Later I helped him change the warm white LED light of RA95, and the problem was gone. Blue light damage varies from person to person. For some sensitive people, excessive blue light with high color temperature plus glare will cause serious symptoms immediately, while for some people, it may only be slightly inappropriate, and after a period of time, they will not feel much after getting used to it. But the damage is certainly there. Of all artificial light sources, leds with an index above 80 have the lowest proportion of warm white blue light, while those with a positive white blue light are in the lower middle, meaning that leds with an index above 80 do no more blue light damage than CFLS. Originally according to the standard LED lamp display index is above 80, but now many led tape light are around 70, the extreme of more than 60 points. At the end of the day is responsible for not responsible, now we are all LED light measurement standards, the vast majority of people only standard is “bright enough”. Taobao see light source products, evaluation is a lot of baby good, very bright. Now that you have all the brightness as the only standard, manufacturer is happy, of course, because the same chip, do show index 70 lights, brightness of at least 10% higher than show that index 80, lower cost and low index, such as 2835 lamp bead, you are not required to display index, 3, 4 cents a 60, 26, 7 lumens brightness. Requirements to show the index, more than 80, basically in 7 points 8 points a star, brightness 24,5 lumens. If you do more than 90 display index, basic to 15 fen or even higher, brightness 21,2 lumens. So the higher the display, the more expensive it is and it doubles, and the brightness keeps dropping, and finally you have the really good stuff, the expensive stuff, and it’s not as bright as somebody else’s cheap stuff with the same power. Can not sell ah, manufacturers are not willing to do ah, anyway, everyone see brightness, then do “high brightness good goods”.
