I have had contact lens since I was a senior high student because I am afraid that the glasses will make my eyes distortion and bulgy. It is nearly seven years. Here I have my own understanding sharing with you.

When wearing contact lens, you must pay enough attention to the sanitation. You should wash your hands before touching them. And the tending liquid with omnipotence is quite nice. I get used to changing them every season. There are other kinds which can be changed every month or every year. I remembered that once I didn’t change in time, I got keratitis finally. So don’t forget to change them regularly.

You must not surf the Internet when you are wearing contact lens. It will lead to cataract, which influences people’s life greatly. It was reported that a boy with contact lens became blind when he was having a barbecue. He was rather close to the fire there. It is very terrible. So we should be careful at any time and keep away from the fire.

The more famous the brand is, the stronger the ability of studying and productivity is. At first, I wore contact lens with thickness of 0.14 to 0.09. They are certainly not so comfortable, but they are fit for those who didn’t wear them before. Some contact lenses just have the thickness of about 0.035mm. They are quite comfortable while the price is high at the same time. Some contact lenses have strong inserted ability, for which they are not so suitable for everyone. People whose eyes have much secretion are not suitable for them. So before buying contact lens, you should know some information about the product.

I wore contact lens all the time except when I was sleeping. When my eyes are in tears, felt dry or aching, I didn’t pay enough attention to my eyes, let alone go to see a doctor. So the result was quite bad. There grew a calculi in my eyelid. The doctor strongly recommended that I should give up contact lens. I feel very regret about my poor eyes now. I didn’t take good care of them but destroy them totally. Now I wear back glasses. How I wish that I had noticed every details before!

Presbyopia is a normal physiological phenomenon. In the young years, people’s eyes are very strong in the regulating force, so that people are able to see objects breezily whether near or far. However, as time goes on, the adjustment of eyes gradually declines, and the line of sight becomes ambiguous, so that, at this time, people need to wear convex lenses in order to see clearly.

The presbyopia in the early days can often go with the following symptoms:

First, when reading the close materials, people need to shift them far way so as to be able to see clearly.

Second, people usually find it difficult to read the small prints.

Third, their eyes are easily to be fatigue while seeing objects not far. 

Fourth, for people to read books, more lighting light is generally required.

Fifth, people often feel headache after the close work; meanwhile, a sense of eye acid appears more frequently.

Sixth, shortsighted ones find out that, after the presbyopia occurs, they need to pull off glasses more while seeing close objects.

Thus, in view of the above occasions, a special type of progressive multifocal glasses is designed. They are especially created for primary and secondary school students. After putting on short-sighted eyeglasses, most of students are engaged in close works. Originally, the mild myopia people, when watching vicinity, require no adjustment at all; but after wearing myopic eyeglasses, looking at the close objects will stimulate adjustment, which will easily cause visual fatigue, resulting in the continued development of myopia. Therefore, progressive multi-focal glasses are especially designed. They are characterized by:

1) From far to near, there is a row of refraction, which enables people to achieve a higher resolution when seeing different objects whether far or near.

2) To coordinate the regulation of human eyes, so as to make it more in line with the normal visual physiology, and to delay the development of myopia, and at the same time to reduce the emergence of eye fatigue.

The groups that progressive multi-focal spectacles are suitable for:

First, farsighted (or presbyopic) people, especially those who have frequent changes in seeing objects near or far;

Second, people who have a higher requirement for appearance and comfort;

Third, those myopic ones over the age of 40, on whom presbyopia starts, and in general, they need to put off eyeglasses or exchange two different pairs in order to see near or far.

All in all, multi-focal glasses provide people with full clear vision, and have been increasingly favored by the majority of presbyopic patients. Currently, to wear a pair of farsighted glasses has been the past; whereas, to own a set of progressive multi-focal glasses is the real manifestation of modern people toward high-quality visual effects, and a good choice toward healthy life.

My sister is a workaholic. Every week she spends one day on the car, two days on the air and three days before the computer. Even on the airplane, bus she still works. Every time our family has a dinner, the missing one is my sister. She is too busy to have a dinner with us. Only on the Christmas Eve can I see her.

But yesterday when I came home, I saw my sister sitting in the chair. How amazing! I ran to her and she gave a huge hug.

“Sister, how could you come home today? Are you fired?”

“no, I’m not fired,” my sister laughed,” I am on holiday. This week I won’t go to work and I can do everything I like.”

“How wonderful it is! We can go shopping together!”

At this time my mom came out from the kitchen,” your sister need relax, don’t let her be too tired.”

“Ah, what’s wrong with you? Are you ill? Tell me!”

“Not a big problem. Just something was wrong with my eyes. I have put on contact lenses on the air, I just forgot, I was too busy. I worked 14 hours that day and totally forgot my contact lens. So that night when I finished my work, my eyes were really hurting.”

“My poor sister, you shouldn’t do this again. You pay too much attention on your work and your body just protested.”

“I know. So the next day, I went to see the doctor and asked for a week’s leaving. The manager agreed. I knew Linda will be busy this week-she has to do more work.”

“Anyway, you have done right. Your manager owes you many holidays. Though you earn much money, but your body can’t support and give you warning.”

“En, so now I have a week holiday, tomorrow when you finish school, we go out for shopping, ok? We will have a big dinner in the downtown.”

“Wonderful! Do you know you should do this long before, my dear sister?”
