Now spring has come and the sun rays are becoming more and more intense. I am sure all of us would think of buying sunscreen or sunshade to protect our skin from being burned by the strong sun rays since protecting our skin from the sun has become a common sense. However, I am afraid few of us are aware of the damage caused by ultraviolet radiation to our eyes, and I myself included. It was not until several days ago that I realized the terrible harm caused by the sun to our eyes.
That day when my 10-year-old son went back home from school, he asked me to buy him a pair of sunglasses earnestly. I felt strange about his requirement. In my opinion, sunglasses are not necessary or even useless to children. What is more, my son is near-sighted and has to wear prescription eyeglasses all the time. “Why you need sunglasses? I do not think it is of any practical use to you. You know, you are near-sighted and you cannot see clearly without wearing prescription eyeglasses.” I asked him. Then he told me the reason.
He said that in that day’s hygiene class, the teacher told them the serious effects of sun rays to people’s skin and eyes. Too much exposure the sun’s ultraviolet rays can cause some serious eye diseases such as cataracts and macular degeneration. We may not aware the effects immediately, but they would show their influence when we become old because the damage is cumulative alone with the increase of time which we expose our eyes to the sun rays.
At first I did not believe what my son said, or I did not think it could be so serious. I searched the internet for information about the damage caused by sunrays. I was shocked by what I saw from the computer. There are a lot of scientific reports about the serious harm of sunrays. My son’s words were not exaggerated at all.
I decided to buy my son a pair of prescription sunglasses to protect his eyes from being damaged by too much exposure to the sunrays. I had no time to shopping around local stores in order to buy a pair of prescription sunglasses. So I chose to buy one online. That same evening I ordered a pair of prescription sunglasses from the net store http://www.cheapprescriptionglasses.net/. Now I have received the goods, though it is much cheaper than those sold by local stores, its quality and style are really excellent! Wonderful to buy prescription sunglasses online!
