New research has revealed “blu” rays, which are caused by the sun’s ultraviolet light, are harmless and should be treated as such.
The research, published in the journal Nature Photonics, said the rays emitted light that is very bright and thus does not cause damage to human eyes.
But it is not yet clear how much light a human’s skin gets.
“This study, although well-designed and carried out by a team of researchers, is still relatively small in terms of its scale and is not an exhaustive analysis of the potential health impact of this rays,” said Dr Michael D. Brown, a researcher at the University of Arizona in Tucson and lead author of the paper.
“We know from previous research that these rays are harmless.
In addition, many people have been exposed to them.”
I’m hoping the next step will be to determine whether they pose any risk to humans, as well as other animals, by determining their exact location on the retina.
“Dr Brown told the Associated Press news agency he hoped the research would lead to new ways to safely treat the rays.”
It’s a bit like taking a bath.
If you don’t wash your hands, you’re going to get sick, but the question is, can you wash your eyes and the answer is yes, we can.
“In the long run, I’m hoping this will help us make safer, more effective treatments for people with certain types of eye disorders, such as macular degeneration.”
Scientists said the findings could provide more insight into how the rays can cause damage.
“These findings could help to address the questions of how much ultraviolet light a person gets and whether they are damaging the eye,” said Jennifer Hoch, a University of California, Los Angeles, professor of ophthalmology.
“But this work is far from definitive, and there’s a lot of work still to be done.”
“This work may shed light on the mechanisms underlying the potential damage to the eye from this UV-B ray, but more work is needed to determine if the UV-A rays, produced by natural sources, are a better target,” she added.
“Ultimately, the best way to protect eyes from UV-radiation is to wear sunglasses.”
Scientists are not sure if there are any long-term health benefits from wearing sunglasses, but they said the new study showed the rays were harmless to the human eye.
“The findings support the idea that the UVB rays do not pose a health risk to people,” Dr Brown said.
