Found that there are a lot of stores are trumpeted a glasses, some shop called the glasses computer radiation-proof glasses, some is said the blue glasses (several times as the coyotes glasses), and, anti-fatigue glasses and is the fifth generation... OK! I suddenly had some curiosity about this anti-glare anti-radiation anti-fatigue.
The sky is blue, what harm does blue light have?
My young, fragile, fragile, fragile spirit can only comfort itself after suffering from the ruthless tyranny of the boss. Yes, the sky is blue, the blue blue has the hair harm.
Take a closer look at all the information about the dangers of blue light, and they all point to a high-tech: LED. Yes, you read that right, the LCD, the lamp, the car headlights, even the leds used in the flashlight.
We use the most, this white LED. To make it glow white, let the LED chip emit blue light, and then the phosphor powder emits yellow light, and the two colors of light blend into the white light. Specifically for the color palette, if you want the LED to be whiter, increase the amount of blue light. If you want the LED to warm up, cut the amount of blue light.
I'm sure not to mention that we all understand that the most blue light we have in our daily lives is from a variety of LCD screens. How does a liquid crystal display, once marketed as a synonym for health, have become a danger today, from mobile phones to computers to tablets to televisions?
In real life, whether we're lying in bed with our cell phone or sitting at our desk in front of a desk, the blue light of an LED light continues to bombard our rod cells. The scientists then discovered a phenomenon that after the rhodopsin decomposition, the material that was produced after it was decomposed absorbed 330-420 nanobands of violet and blue light. But the uv light below 400 nanometers is invisible to the human eye. So that's why blue light can cause retinal damage.
There, into the eyes of the blu-ray will pass a light to reverse, will already decomposition of rhodopsin direct reduction into normal function of rhodopsin, rather than follow the normal rhodopsin synthesis process. As a result, the energy of the rod cells has been greatly enhanced, and the human eye's ability to capture photons has been greatly improved.
But is this promotion good? In further experiments, we found a new phenomenon: apoptosis. As the human eye enhances the photon capture capability, the apoptotic process of the photoreceptor cells is activated and the retinal damage is caused when the light illumination of the human eye reaches 380kj/m2.
So, blue for retinal damage, can be simply summed up in this process: too much blue light into the retina and retinal photoreceptor ability improved, when the retina capture photons after reach a certain amount of retinal cells begin to die, and retinal damage.
