The invention of the glasses by Benjamen Franklin in 1780s had given a solution  to myopic eyes, and it has become the most common accessories in our life. The Impaired vision had affected 4.2 billion people in the world, and according to the research in America, the 3 out of 4 people in the States will have vision problems, and 71% of them are wearing glasses and 22% of them are wearing contacts. The enormous surge in diagnoses had happened in past decades, and from 25% to 41.6% of the American population are getting the nearsightedness. And the number is keep rising year by year, and in public places, more and more people are wearing or have a pair of glasses in prepared, and why?

The first reason is the booming of displays and the technologies. People are getting around with different kinds of display, like cell phones, Laptop, television, etc. They were causing the tiredness of the eyes by staring at the display for a certain amount of time. The eye will have been shaped in physically too long. The eye focuses light will be affected by tiredness and in turn pass the high possibilities to nearsightedness. For instance, reading a book in incorrect distance between book and eyes or in not efficient lights can also lead to the nearsightedness. Besides that, the genetic predisposition is also a factor to cause the myopia in children. If one’s parents are myopia, and there will be a greater chance of their kids to get myopia. In addition, the infection, caused by hand-touch or other not proper touch, can also result to the myopia. In the search, “Other forms of myopia can occur after surgery, or exposure to various harmful chemicals.”

For the other group of people, instead of preventing their vision, they wear glasses just for fashion, nothing but. They believe that wearing glasses can make one look more intelligent and brainy. It can cause the good first impression of being stylish, and friendly.  Besides, that due to the research of the scientist, glasses have the function of balancing out one’s face to be more symmetrical. There is another interesting function of the glasses, that has been developed recently, it helps one to cover up one’s emotion and anxiety, “Glasses cover not just the eyes themselves, but the surrounding tissues, the cheekbones, the frown lines,” Handley says. “These are all indicators of what you mean and are trying to say.”
