The first one: in the middle of the 13th century, there was a British scholar – Bacon. He saw many people’s vision were so poor that they couldn’t see the words of the book. Hence, he wanted to create a tool to help people improve eyesight. For this, he came up with a lot of methods and did a lot of experiments, but without success. One day after the rain, Bacon came into the garden for a walk and saw the cobweb with a lot of rain. And then he found that the leaf veins became larger when he saw it through the raindrop. Even he could see the fine hairs on the leaves. He was very happy after he found this phenomenon. And then, Bacon immediately ran home, and found a glass ball. However, through the glass ball, the words still were fuzzy. He took out a diamond and a hammer, and cut a piece of glass. He put this piece of glass near the book and read the words. This time, the words were enlarged. Experiment succeeded. Bacon was mad with joy. Then he took out a piece of wood, dug out a round hole on it, and put a piece of glass. At last, he set up a handle in order to make it easy to hold. Using it, it’s more convenient to write and read for people. Later, after continuous improvement, this kind of lenses became the eyeglasses which people wear now. Bacon made important contribution for human civilization progress.

The other one goes like this. The first person who thought of improving people’s vision with glasses is a scientist came from Florence. About in the A.D. 1280, he used a pair of convex lenses to correction farsightedness. However, he revealed his idea of invention to a friar who came from Pisa. Later, the friar told others how to make glasses, and also pointed out how to make glass become tortuous. In 14th century, many Italians were wearing glasses. But until the 15th century, the concave lenses which were used for correct myopia were produced. However, the glasses didn’t catch on quickly. This was mainly because the lens grinding skill didn’t get full of development. In 17th century, lens makers still had difficulty in producing good lens. At that time, microscopes and telescopes were still in development. After that, many different glasses appeared, including prescription eyeglasses, prescription sunglasses and so on.

I really do not want to mention the prescription glasses I am wearing now, since every of my classmates are keeping saying that they look very ugly and ridiculous. Besides, they even humiliated me once, which is a shame to me. That was when I was spending my winter holidays at home. One day, after I watched some boring television programs, I just grabbed my prescription eyeglasses off and threw them onto the sofa carelessly. Then I went to the washroom and I totally forgot that my poor eyeglasses were still lying helplessly on the sofa while not where it should be—the glasses box. As a result, when I came back from outside and threw myself into the sofa, I felt something groaning as if in pain. Oh my God! It was my pair of prescription glasses! I hurriedly picked them up and examined them carefully. Fortunately, I found they were still in good conditions except that the frames of them were a little twisted. I brought the glasses to my mother to ask for a new pair. Naturally, I was scolded severely for my careless treatment to my glasses and also because, a pair of ordinary prescription eyeglasses cost a lot in the store on the roadside. What’s more; my mother said that since my eyeglasses could still be put into use, then there was no need for me to buy a new one. What could I say furthermore? After all, it was my fault totally. But you could never imagine how weird it looked by wearing a pair of leaning eyeglasses on your face. My friends were all very curious about my prescription glasses and always ridiculing me for this. Therefore, I do have good reasons to get rid of them as possible as I could. I only wear them in the classes now, but I feel that my eyesight is becoming worse and worse since I often have to view the world in a lean way.

Since then I had got my eye glasses. They are unique in the form and their frame is red. It helps me see things clearly from a distance. Meanwhile, it can protect my eyes when I watch TV and operate a computer. I am so grateful to them.
