How to solve the problem that wearing a mask often fogs the eyes? What is the principle of anti-fog mask?

During the epidemic, masks have become a must-have fashion item for everyone. Everyone must have a mask in his hand. When you walk down the street, you will see everyone wearing a mask. When the Wuhan epidemic broke out, masks became scarce materials. Try not to go out and wear a mask when going out, which became a common state at that time. Leaving the scarce materials where they are most needed, all localities began to donate them to Wuhan, and materials from all over the country warmed the hearts of Wuhan people. Medical staff from all directions helped Wuhan and let the people of Wuhan see hope.

But at the same time, we will encounter many problems that need to be solved. Many medical personnel wear glasses, protective clothing and masks, and often paste a layer of fog on their glasses, which affects their vision and thus their work. In order to solve this problem, a student in our country invented an anti-fog mask, which will actually bring great help to medical staff. On the basis of the original mask, the inventor designed a wave-shaped gas barrier to prevent glasses from fogging. After he designed it, he tried it on and felt the effect was particularly good. Then he discussed with his father and donated the design to a mask manufacturer for free, so that more people could share his innovation. Very young, but insightful, practical and innovative.

The principle of anti-fog mask is to block the way of exhaling air through some small designs on the basis of the original mask, so as not to let the air paste on the glasses. Use a little skill to make the work of medical staff simple and convenient. It is these creative inventions that make our life full of many possibilities and endless fun. Creative people can often see the world from an innovative perspective and dare to challenge all the problems in the world. As long as you are willing to work hard and innovate, nothing can't be solved. I believe that these humble inventions will also bring infinite possibilities to our world.
