LED lights consume about one-fifth the energy of incandescent bulbs of comparable brightness, and they are already commonly used for home, street, office and industrial lighting. They are also increasingly found in car headlights, flashlights and some toys.
We all know that sunlight is composed of the colors red, orange, yellow, green, blue, indigo and purple. Our daily life of various artificial light is the same, whether it is energy-saving lamps, halogen lamps or LED lights, they will emit white light, but also because the light contains the blue component.
Is the blue light of LED lights more?
LED like various other artificial light sources, also contain blue light components. According to the spectrum analyzer measurement, the blue light content of LED is in fact the same as other energy-saving bulbs, incandescent bulbs (in the same light color premise, for example, are warm white light or are cool white light). Simply put, LED is the same as other light and will not cause more damage because of the blue light component.
Does blue light cause damage to the eyes?
Light is a form of energy. We see light because light forms an image on the retina, and as it forms an image it also accumulates energy. This energy, if accumulated too much in a short period of time, can cause damage to the retina. Various colors of light do not carry the same amount of energy at the same brightness. According to scientists, blue light because the wavelength is shorter, so it is easier to penetrate the eye, so the impact on the retina than other colors of light is higher, which is the reason we often hear that "blue light hurts the eyes".
What can I do to avoid my eyes receiving too much energy in a short period of time?
For the eye to see images, the light-sensitive cells in the retina have to receive energy, the right amount of energy to allow us to see without causing damage to the retina. But staring at a light source for a long time and at close range can cause damage to the retina.
Generally speaking, the regular manufacturers after the national quality inspection of the products listed, there will be no hidden danger of excessive blue light. To avoid eye damage from blue light, there are several things to keep in mind:
1. Adjust the height and angle of the light source of the lamp to avoid the eyes in a normal sitting position to see the light source, do not deliberately close to stare at the light source.
2. Home lighting can consider using some "warm white" LED lights to reduce the damage to the eyes.
As long as you can do the above, reading under a desk lamp even if you look too long retina will not be harmed. But in addition to the possible hazards of blue light, myopia is the biggest killer of children's eye health, so when reading books or have to remember to brighten the lights, keep your eyes at a distance from the book, while every 30 minutes to rest for 10 minutes, so as not to be myopic.
