Heard horror stories about the harmful blue light?
There are new stories on the topic. About blindness and beauty. First talk about blindness.
It is said that the color blue from the screens of electronic devices can damage the retina and lead to blindness. This is nonsense.
The story began with research at the University of Toledo. Blue light irradiated visual pigments. And not even the pigments, and the part of the pigment, which receives light. This is an aldehyde form of vitamin A, which is called retinal.
If the irradiated retinal blue, then it can become harmful to cells. In fact, he and no light is toxic. Just retina is able to block the harmful effects of special protein.
Retinal can enter the bloodstream and act on other cells in our body. No one had not occurred poobluchat light in the head is not the retina, and other cells to see how behave retinal. Researchers from the University of Toledo is done and checked, everything happens in a test tube with different cells.
An interesting study, but no practical conclusions were not, and the recommendations of the scientists did not give. Just spotted journalists combination of blue light and damage to retinal cells, and then fanned out of molehills. As usual, someone has misunderstood something.
The American Academy of Ophthalmology, even special article on this subject published so that people no longer hysterical.
In my laptop there is a night light mode, and the phone - eye protection. If you enable protection, the screen turns to yellow. Sometimes very horrible from such protection.
In fact, the blue light does not hurt the eyes. But it can disrupt the circadian rhythm of sleep and wakefulness. About it tomorrow to tell apart.
Are you scared? I do not.
