Too long eyelashes can damage your eyes

When praising someone for their beauty, people always say that they have a pair of beautiful big eyes and long curved eyelashes, which are really beautiful. But everyone knows that too long eyelashes can be harmful to people. Everyone always thinks that the longer the eyelashes, the more beautiful they are. They are beautiful, but do you know what the dangers of too long eyelashes are? Let me tell you about the dangers of too long eyelashes.

Key points: Researchers believe that eyelashes of this length can effectively block and reduce the air flow to the eyes. If the length exceeds this, not only will it not block the air, but it will become a "funnel" for air to reach the eyes, increasing the evaporation of water in the eyes and the accumulation of dust.

Many people desire long and thick eyelashes, but the longer the eyelashes, the better. After studying the length of eyelashes of 22 species of mammals, scientists from the Georgia Institute of Technology in the United States concluded that the "optimal length" of eyelashes is 1/3 of the width of the eye. If it exceeds this "optimal length", its effectiveness in keeping the eyes moist and refreshed will be reduced, and excessively long eyelashes may even affect eye health.

Eyelashes have a filtering function, which can prevent dust from entering the eyes and prevent moisture from being lost. "We found that the filtering function of eyelashes helps reduce the accumulation of particles (dust) in the air in the eyes," said Guillermo Amador, a doctoral student at the Georgia Institute of Technology and one of the researchers. The researchers used wind tunnel tests to study the role of eyelashes of different lengths in keeping the eyes moist and dust-proof. The results showed that when the length of eyelashes is 1/3 of the width of the eyes, water evaporation and dust accumulation in the eyes are reduced by 50%. Researchers believe that eyelashes of this length can effectively block and reduce the air flow to the eyes. If the length exceeds this, not only will they not block the air, but instead they will become a "funnel" for air to reach the eyes, increasing the evaporation of moisture in the eyes and the accumulation of dust. In other words, too long eyelashes will make the eyes drier and dustier. When the length of eyelashes exceeds 1/3 of the width of the eyes, the evaporation rate of water in the eyes will increase.

The research results not only help people promote eye health, but also have important significance for human exploration of space. Guillermo Amador said the research could help improve the cleaning and maintenance of space exploration equipment, such as the solar panels on Mars rovers.

I have talked so much about the dangers of having too long eyelashes above. I hope everyone will pay attention to the problem of too long eyelashes in daily life. Because too long eyelashes can cause great harm to the eyes, women who love beauty should not use false eyelashes and try to use less mascara, which will also affect our eye health. Please pay attention to the dangers of having too long eyelashes.
