What are some of the difficulties of being blind? Two hundred years ago, a little boy was born in France. He was Louis Braille, a happy and lovely baby.
Sadly, when he was three, something bad happened. While playing in his father's shop, Louis hurt his eyes on a sharp thing. Although he got the best care at that time, he was still completely blind and could not see all the lovely colours and beautiful things around him.
Louis was a kind boy. As he grew older, he wanted to help other blind people read. However, it was really hard for him. The first way he tried was to poke (戳) holes in paper and read by touching raised (凸起的) letters with his fingers. But it was too slow to read the letters and few blind people could do it well. After that, he tried many other ways.
One day, Louis heard about someone using dots to represent (代表) sounds. He immediately found its advantages and he spent three years improving upon this idea. Finally, he made a special alphabet and blind people could feel it with their fingers. Each letter was made with a number of dots and people could feel them by their fingers.
The alphabet that Louis made is called 'Braille'. Today many blind people use 'Braille' to help them to read. This is how the Braille Alphabet looks:
Haiyan is 7 years old. Her parents gave her an iPad as a gift for her birthday. A month later,her eyesight(视力)dropped to 300 degrees. This is serious for such a young child.
Many children in China are facing the same problem: iPad using is bringing problems to their eyesight. The problem is so common that newspapers even call the iPad the "No. 1 killer of children's eyesight!"
"There are about 30 shortsighted children coming every day, "said Hu Dali, an eye doctor at Guiyang Aier Eye Hospital. "Half of those children have poor eyesight because they have played with phones and iPads for too long. "
Doctors and scientists say children's vision(视觉)is not yet fully developed and their eyes get tired more easily. The screen of an iPad uses very bright(明亮的)LED backlight. If children look at an iPad screen for a long time, their eyes do not have time to rest. This will make their eyesight worse over time.
Doctors advise that users should hold their iPads between 40-60 centimeters(厘米)away from them. The brightness of the screen should be comfortable for children. Parents should also stop their children from using an iPad for more than one hour every day.
