Blue light from mobile phones and computers accelerates skin aging

15 Mar 2022   author: noname

We spend more and more hours a day staring at our phones, tablets or laptops. Modern technologies grasp us and separate from the outside world. But perhaps now the time you spend looking at the screen or monitor will be reduced. They emit blue light that is highly energetic and penetrates deep into the skin and accelerates its aging. 'Blue light can penetrate deep into the skin, into the deeper layers where collagen and elastin are produced, and the skin becomes thinner and more fragile. Increased exposure to this light can cause noticeable oxidative damage to the skin,' says a British dermatologist.

Antioxidants primarily protect against the negative effects of both blue and ultraviolet radiation. They neutralize the free radicals that these light spectra produce in tissues. Strong antioxidants are polyphenols from green tea, chocolate, or red wine, various colorants in fruits and vegetables, or vitamins C, A, D, or E.

And what's worse, American scientists have shown that long and regular staring at computer monitors, mobile phones or tablets seriously impairs vision. The blue light emitted by these devices, which also disrupts the human sleep cycle, produces toxins in the cells of the retina. If it accumulates on a daily basis and for a long time, the retina dies and blindness is likely to develop in the person in time.

"Prolonged exposure to short-wavelength light produces toxic substances in retinal cells and provokes macular degeneration in the retina, which can lead to blurred vision or a dark spot in the center of the visual field," say scientists from the University of Toledo in Ohio.

"It's no secret that blue light damages the retina. Our experiments have only explained how this happens at the molecular level. We hope that these discoveries will lead to the prevention or treatment of macular degeneration on the retina," said the doctor from the University of Toledo.
