Blue light damages our body, its negative impact is confirmed

Many people wonder what damage blue light causes?, or how does the light of the cell phone or the computer affect the eyes? In this blog I have already talked to you several times about this topic, I have given you tips to protect your eyes with filters against the blue light of the screens and I have even recommended several applications to manage the intensity of this type of light emitted by your eyes. screens.

There is still a lot of controversy about the impact of blue light from screens

Despite the fact that we are increasingly aware that blue light is not neutral for our body, there is still much controversy about its impact on our body and of course on our eyes. That is why it is good that scientists continue to investigate and publish new studies that allow us to be clear about whether blue light is bad or not. Today I’m going to tell you about a new study that has investigated the impact of exposing fruit flies to blue wavelengths of light.

The research, which was published in npj Aging and Mechanisms of Disease (link at the end of the post), consisted of observing the effects of subjecting flies to different lighting conditions.

The researchers found that flies exposed to 12 hours of light and 12 hours of darkness had a shorter lifespan than those kept in the dark all the time, or exposed to one light emission but with its blue wavelengths filtered out.

Damage to your retinal cells, your neurons and locomotion problems

The flies exposed to blue light showed damage to their retinal cells and brain neurons. They also suffered locomotion problems.

Professor Jaga Giebultowicz, from Oregon State University, highlighted that there is evidence to suggest that increased exposure to blue light is a risk factor for sleep and circadian rhythm disorders.

LED lighting has not been used enough to know its long-term effects

“With the frequent use of LED lighting and displays, humans are subjected to increasing amounts of light in the blue spectrum, as commonly used LEDs emit a high fraction of blue light. But this technology, LED lighting, even in most developed countries, has not been used enough to know its long-term effects on humans.”

Interesting, right?
