The daily effects of blue light emitted by your phone or computer can accelerate aging, even if it does not get in your eyes. This emerges from a new study on fly models, stating that the blue wavelengths generated by light emitting diodes damage cells in the brain as well as the retina. : Health - Asume Tech

The daily effects of blue light can accelerate aging, even if it does not get in your eyes
Prolonged exposure to blue light, such as from your phone, computer, or household appliance, may affect your life, even if it does not glow in your eyes.
New research at Oregon State University suggests that the blue wavelengths produced by light-emitting diodes damage both brain cells and the retina.

Light is vital but prolonged contact with artificial light is more important to health. In the blue spectrum, the human being is exposed to an increased amount of light generated by light-emitting diodes (LEDs) that can disrupt normal sleep cycles. The LED technologies are relatively new; Therefore, the long-term effects of exposure to blue light over the lifetime are not understood. We studied the effects of light in the model organism Drosophila melanogaster and found that flies that were kept in daily cycles with 12-hour blue LED and 12-hour darkness compared to flies that were in constant darkness or in blue with blue were kept significantly less lifespan blocked wavelengths. The exposure of adult flies to 12 hours of blue light per day accelerated the aging of phenotypes and caused retinal cell damage, neurodegeneration of the brain, and movement disorders. We report that brain damage and movement disorders do not depend on degeneration of the retina, as these phenotypes were visible in flies with genetically-degraded eyes under blue light. Blue light induces the expression of stress-sensitive genes in old flies, but not in young ones. We also found that some known blue photosensitive proteins do not act in pathways that mediate harmful light effects. Our study unveils the unexpected effects of blue light on the fly brain and establishes Drosophila as a model for studying the long-term effects of blue light on the cellular and organizational levels.
