Oil in tears

When studying the components of tears, scientists at the University of Ohio, USA discovered a type of oil-like fluid that has never been seen before. This finding may help them find a cure for dry eye.

Kelly Nichols, an assistant professor of phototherapy at Ohio State University, said the researchers have identified a material that forms the surface of the oil layer, ie the fat-rich Animo-compound acid. This is a new type of fat that people have never met.

In addition, researchers also discovered Amide oil. Amide oil is involved in regulating sleep, and has been shown to trigger news communication between nerves.

Amide oil or any other type of fat when not enough or too much, the oil layer may lose its ability to retain water, leading to dry eyes.

Eye dryness not only has one form but several forms, including headaches, inflammation, dryness and tears. These symptoms all affect the vision of the patient. In the United States, about 14 million people suffer from this disease.

This finding will help doctors find a simpler way to test dry eye: Take a tear sample, press the button, receive biological indicators, from which you can tell if you have dried up. eye or not?
