The Dhaka Times Desk We may never have thought about eyelids. But this time, some information about the mysterious eyelids has come out. This report analyzes this issue.
Eyelids have been buzzing and whispering among scientists for a long time. According to some scientists, the eyelids act like filters to prevent dust and harmful substances from entering the eyes. Others say that it acts as a kind of sensor like a cat's whiskers; It also alerts the eyes to airborne sand and hazards. Why do humans and other mammals have petals in their eyes? Researchers have been studying this issue for a long time.
A group of biologists said in their recent research report that the eyelids filter small particles, microorganisms, and infectious germs in the air and help the air to flow into the eye. The report was published in the journal The Royal Society Interface.
A group of scientists led by David Hu of the Georgia Institute of Technology in Atlanta, USA, conducted this new research on eyelids. They conducted this study on a total of 22 species of mammals, from monkeys to humans.
According to scientists, the flow of air is able to flow in a controlled manner through the petals to a satisfactory level in the eyes without creating any obstacle on the vision. These petals protect the eyeball from drying out of the coating consisting of mucus, oil and water. Not only this, it also acts as an indirect dust control system. The petals protect the eyes from dryness and infection. Studies have also shown that children with allergies have eyelashes that are 10 percent longer in length and thickness than other children.
The researchers also found that some animals, such as giraffes, have multi-layered eyelids, which protect their eyes from dry and excessively dusty environments.
It should be noted that many people think that the eyelids have a special effect on the face of people in terms of establishing contact with others and attracting people.
