New research shows that pigments in our nose and eyes are key to protecting us from the harmful effects of sun exposure.
The research was published in Nature Communications.
The findings may help identify and potentially treat some of the more common forms of eye damage, such as cataracts.
“Our nose and eye pigments have a huge role in protecting us against the damaging effects of sunlight,” lead author Dr David M. Cunanan from the University of Exeter, said.
We’ve known for some time that pigmentation in the skin and the eyes helps protect us from UVB rays, but what is more surprising is that we don’t see the benefits of these pigments on the surface of the skin.
“Our skin is a very thin, flexible membrane that can be exposed to UV rays, and it turns out that pigmenting the skin also protects us from damaging UV rays.”
This has been an area of ongoing research, but we had no idea how pigments work.
“The scientists used a high-speed camera to record the skin’s surface.
They then analyzed the images with a spectrophotometer, which uses light to determine the density of different pigments.
They found that a very specific type of pigment in the nose called anthracotic pigments was present in the surface layer of the human skin.
Anthracotic is the name given to the natural pigment found in pigments found in our skin and eyes.
It is composed of molecules that can break down into smaller, lighter molecules when exposed to sunlight.
It’s the same molecule found in the pigments we use in the body, like vitamin D.”
What’s amazing about the pigmentation is that it works in a completely different way from the natural pigments,” said co-author Dr Chris Haines from the National University of Singapore.
This is because the pigment is a living, living part of our skin, not just a pigment that can absorb sunlight.
Haines and his team found that anthracotics in the eyes were the most effective at protecting the eye from UV rays because they absorbed the most UVB radiation.
This is consistent with previous studies showing that anthrax was also a major source of UVB light.
Although the pigmented skin has a huge protective effect, it is not the only source of pigments that protects our eyes from UV radiation.
Pigments are produced in the eye, skin and muscles, which are all covered by a layer of corneocytes.
In our eyes, the corneocyte is the innermost layer of our retina, which is where light-sensitive cells are located.
But corneodes are a very complex organ.
They are packed with hundreds of millions of cells that respond to light and are made of a unique polymer called glycoproteins.
They work together to form a flexible, flexible structure that acts as a kind of lens.”
The eye, like the skin, has its own unique system of photoreceptors that work together,” Dr Hainess said.”
So even though our eye is a part of the cornea, it doesn’t get all the light it needs.
“We’ve found that if you take out the corns, that this plastic lens changes and we can see the corona much better.”
While the research was initially designed to help treat cataract patients, it has potential applications in the general public.
The researchers believe that these studies will help identify which pigments can help protect against cataraches and other eye conditions.
As the world moves to a low-emission future, the future of the eyes and skin is being upended.
“One of the most exciting things about this research is that the researchers have shown that a particular type of pigment in the coronal layer of eye can help with vision,” said Dr Cunanas team leader Dr David Cunan.
