IMPORTANT NEW EVIDENCE: Study by the University of Oregon confirms blue light causes premature aging, damages retina cells and impairs brain functions

Published by the journal Nature, the new study from the University of Oregon (UO) confirms the results of the scientific experiments with fruit flies exposed to blue light, die much earlier than those that are not exposed, showing a 42% difference in mortality between the groups.

The researchers were amazed that the animals exposed to blue light not only lived a shorter span of life but their quality of life was also much poorer. According to the researchers, the limbs of the exposed animals were seriously affected and they found severe damages to their brains, impairing locomotion and affecting the flies’ ability to climb the walls, which is their common behavior.

The most affected were the Retina cells of the animals, losing around 83% of the cells at about the mid-term of their life span, which are very similar to the results of human cell studies that were presented by the University Complutense of Madrid (UCM) in 2013.

One part of the UO study involved a group of genetically modified flies that lacked eyes that were also exposed to blue light to check the effect on their brain, independently of retinal damage. The results regarding brain functions were similar, indicating that significant harmful effects could also occur even when the flies didn’t have to see the light to be harmed by it.

Other important factors that were found was that young animals revealed less damage than the adults, suggesting that cumulative exposure to blue light acts as a stressful element during aging. It is also noted in the study that the females suffered slightly more damage than males.

Out of the many organisms studied by geneticists in the twentieth century, the fruit fly (Drosophila melanogaster) is one of the most widely used in laboratories. In recent decades, genetic tools such as trans genesis, insertional mutagenesis, and sequenced genome, and experimental tools for investigation of cell biology and development, have allowed study of the basic cellular and developmental mechanisms of fruit flies, similar to other animals, including humans.

The LED technologies are relatively new; therefore, we are beginning to understand more and more the true characteristics of risks and the long-term effects that can cause retinal damages and, now its effects on premature aging, when we are exposed to screens without adequate protection. 

Founded based on 15 years of scientific studies by the UCM, Reticare protectors affixed on device screens completely cover the source of light, preventing light exposure not only to our eyes but also to our bodies. Such as the above substantiated evidence and progression affirm, since UCM’s discovery in 2013 regarding damages to the retina, now new and serious effects of blue light are being revealed, which makes it even more important to protect ourselves from device screens we use every day.
