There are millions of people throughout the world who are either born blind or have become blind over the course of their lifetimes. It is unfair to take away the visual beauty of the world from these people. Doctor Humayun has created the world’s first bionic eye that could change the life of every blind people in the world.

Doctor Mark Humayun is a well respected professor at the Doheny Eye Institute in California. He has been working for years on creating a bionic eye that would allow blind people to see images just like a normal person does. His idea of the bionic eye is actually an eye that has been built in a small video camera.

The test results show the bionic eye has given blind patients the amazing ability to see the scientists doing the tests. But the images are still blurry(模糊的) and we need much work before the eye actually becomes a regular implant(植入物) into blind people. Humayun believes that he can go into production with the bionic eye over the next three to five years.

A closer look at the bionic eye is amazing. The patient wears a special set of eyeglasses. All the signals(信號(hào)) are passed to the implanted eye. It’s done by wireless technology. Humayun has created an invention that could change the lives of millions of people. Imagine a world in which someone would no longer fear about being blind. This could be considered a technological achievement.

Good reading tips:

Try to read at the right level (水平). Read something that you can (more or less) understand. If you need to stop every three words to use a dictionary, it is not interesting.

Then come back when you have finished reading to look them up in a dictionary and write them in your own vocabulary (詞匯) book. Then try to remember them.

Try to read regularly. For example, read for a short time once a day. Fifteen minutes every day is better than two hours every Sunday. Fix (固定) a time to read and keep to it. You could read for fifteen minutes when you go to bed, or when you get up or at lunchtime.
