Take care of your eyelgasses

There are a lot of people who are blear-eyed sufferers or hypermetropic sufferers, and I believe that most of people also know something about those kinds of people. There are people who need to wear sunglasses to protect their eyes from the harm of ultraviolet radiation; and according to the different need there are different sunglasses for distinct people. For instance, there is a kind of sunglasses for those people who climb.
However, there are another people you might haven’t noticed or even never heard of. They are people like me who are presbyopic sufferers. Just as blear-eyed sufferers and hypermetropic sufferers, there are special eyeglasses for each kind of people. However, just like presbyopia is not well-known so that there aren’t some special eyeglasses for us to wear. Even though there aren’t special eyeglasses for us, we have to go on our life.
Therefore, we decide to have two pairs of eyeglasses. When we need to see a thing which is near to us such as we read newspaper and some instruction words, we wear nearsighted eyeglasses; when we need to see a thing which is far away from us, we have to wear hyperopic eyeglasses. I believe that every people hope that their life should be easy, so do we. We expect that one day we are able to only wear one pair of eyeglasses which can let us see anything in this world without changing another pair of eyeglasses. We don’t like the life that we have to take two pairs of eyeglasses with us when you go out for something and we have to change two pairs of eyeglasses for more than ten times. It is very troublesome. We do hope that one day in this world there is a kind of eyeglasses for us to wear.
To our pleasant, at present there do have a kind of eyeglasses which is only for us to wear, and they are bifocals or progressive eyeglasses. I happened to know this news this year. At the beginning, I couldn’t believe it. Whatever, I shopped for one pair in an online eyeglass store which is named bigeyeoptical.com. After I wore my new eyeglasses, it’s true that this kind of eyeglasses is really able to let us to see things in different distance without changing eyeglasses. What’s more, if we have a pair of progressive eyeglasses, there is no need for us to shop for two pairs of eyeglasses every time. We may save a lot of money. It costs us much money every time we have to shop for two pairs of eyeglasses.
I do feel excited that there are some people who care about people like me who suffer from presbyopia. Now I can say goodbye to the old days when I had to wear two kinds of eyeglasses for ever.

I’m a presbyopic sufferer; therefore, I’m unable to see things clearly no matter they are close to me or far away from me. I just can’t see them clearly. At first, I don’t know that there are bifocals and progressive eyeglasses, so I have two pairs of eyeglasses for me to see things clearly. Actually, in the beginning I could accept it because usually I only need to wear myopic eyeglasses. However, as the time went, there were so many things for me to see that I had to change my eyeglasses frequently. As a result, I was tired of it. As a matter of fact, I didn’t like to take many things with me when I went out for something, especially for shopping. Even though they were only two pairs of eyeglasses, I didn’t want to take them with me. However, there was no choice for me; I had to take them with me once I went out.
I remembered that there was a time I went out to shop and I took my two pairs of eyeglasses. When I saw the price of something, I had to wear my shortsighted eyeglasses; however, when I need to see something which was a little bit far away from me, I had to wear my farsighted eyeglasses. I did this for more than ten times. It’s really frustrated. What’s worse, I didn’t buy anything on that day. So I was truly angry with my eyeglasses. I contributed the reason that I couldn’t shop for anything to my eyeglasses. It’s because of my eyeglasses which were so inconvenient that I shopped for nothing. Therefore, I hoped that there’s a pair of eyeglasses which was able to let me see things clearly no matter how far or how near they were to me.
I asked my friends and turned to the internet, finally I found that there was a kind of eyeglasses which was able to satisfy my requirement in an online eyeglass store which was called bifocals and progressive eyeglasses. In fact, I didn’t think much about bifocals and progressive eyeglasses, I even didn’t find any information about this kind of eyeglasses, and I just bought one pair of bifocals and progressive eyeglasses. To my pleasure, this pair of eyeglasses turns out to be excellent. I do can wear one pair of eyeglasses to see anything no matter it’s far away from me or quite near to me.
Now I feel that my world is fantastic again due to my progressive eyeglasses. I can only wear progressive eyeglasses to go out for shopping. I want to see price, then I can see it; I want to see some clothes which is far away from me, then I can see it. I do love my progressive eyeglasses.

Gradually, the bifocal and progressive eyeglasses have become outstanding among all kinds of eyeglasses. They are a kind of new scientific and technological product. On a small lens, there are several diopter prescriptions, which is quite different from common lens that only has one diopter prescription. On bifocal and progressive lens, there are three visual fields from top to bottom for far, middle and near distance. In the middle, distance, the prescription gradually rises from far-distance visual field to near-distance visual field. Hence, wearer is able to clearly see scenery in any distance only by moving eyes and head. While the bifocal and trifocal eyeglasses just can see thighs in two or three specific distance. Therefore, a pair of bifocal and progressive eyeglasses can correct both nearsightedness and farsightedness, and be used as several pairs of eyeglasses at the same time.
Well, are the bifocal and progressive eyeglasses suitable for all wearers? Who are appropriate and inappropriate to wear them?
First, the presbyopia sufferers are suitable to wear the bifocal and progressive eyeglasses. According to the research, in America, there are four million people, especially middle-aged person, who have the trouble of presbyopia, which is different from farsightedness and nearsightedness. Generally, common presbyopic eyeglasses have the problem of image deformation and visual boundary, which make the wearers feel uncomfortable and confused. However, the bifocal and progressive eyeglasses do not bear theses problems. There is no boundary on its lens, so the surface of lens is the same with common lens. Its unique and novel design of lens makes presbyopia wearers more conveniently and comfortably to watch in various distance.
Second, there are many people who need near-distance work and dislike to change eyeglasses for different occasions. Such people can wear the bifocal and progressive eyeglasses. For example, if people cannot see words or pictures when reading or writing, they can wear a pair of bifocal and progressive eyeglasses to help them.
Next, some workers in special fields are not suitable to wear the bifocal and progressive eyeglasses because the design of bifocal and progressive lens is special — its upward areas for far-sighted while the downward for near-sighted. These people include librarian, pilot, electrician, construction laborer, and so on.
People who have obstacle in sport are also inappropriate to wear such eyeglasses. The obstacle in sports is mainly the defect of balanced ability, such as carsickness, seasickness or other similar dizzy symptoms. It is difficult for such people to adjust the bifocal and progressive eyeglasses. Hence, theses people should be cautious if you want to buy a pair of these eyeglasses! Meanwhile, this note is also true of the people who are sensitive to the change of diopter.
Moreover, the bifocal and progressive eyeglasses are not suitable for people who have a bad astigmatism.
Are you the appropriate person? If you are, try to order a pair of bifocal and progressive eyeglasses now! Surely, a new and bright visual field is waiting for you!

Bifocal and progressive eyeglasses have become the new focus of the world attention in recent years.
The bifocal and progressive lens is quite different from common lens. Common lens refers to one prescription, such as the myopic lens and hyperopic lens. While the bifocal and progressive lens compromises the merits of bifocal lens and progressive lens. It is a kind of lens with different prescriptions for different distance in one piece of lens. Namely, the diopter changes from up to down, and wearers can see both the far- distance scenery, middle distance scenery and near distance scenery. Hence, wearers who wear bifocal and progressive eyeglasses do not need to change eyeglasses to see things in different distances.
There are also many other advantages of the bifocal and progressive eyeglasses.
Compared with common bifocal eyeglasses, bifocal and progressive eyeglasses can get the entirely successive and clear visual sense. The common bifocal eyeglasses have a limitation of focusing scope in each visual field, which causes the failure in gaining an entirely successive and clear visual sense. However, the bifocal and progressive eyeglasses overcome this obstacle. For such kind of eyeglasses, its added value increases in the progressive areas gradually and successively, so the wearers can gain satisfactory visual sense on any distance.
Moreover, there is no obvious diopter boundary in progressive lens, which exist in common bifocal lens and trifocal lens. Hence, its lens’ appearance is not different with common lens. Well, its lens is thinner, compared with the same prescription eyeglasses. Therefore, wearers do not need to worry about the beauty of bifocal and progressive eyeglasses. Besides, these boundaries can create image deformation, making wearers feel dizzy or see scenery blurred. But the bifocal and progressive eyeglasses do not have this trouble. And bifocal and progressive lens also do not have circular blind spots. Hence, wearers can enjoy a better and more natural vision effect.
To sum up, the bifocal and progressive eyeglasses are a kind of new technological product. Although now they are not widely popularized to people, wearers prefer them to bifocal or trifocal eyeglasses. A pair of such eyeglasses can replace several common ones, which is both convenient and economical. And they can better meet wearers’ visual requirement.
In addition, if you feel that there is a little change of visual sense, when wearing a pair of bifocal and progressive eyeglasses, do not worry! That is normal. Like other eyeglasses, you need some time to adjust your new eyeglasses. So the bifocal and progressive eyeglasses do. Hence, surely, you will get quickly and well with these eyeglasses.

My father is an engineer; he is now 48 years old. Originally, he suffers from myopia and his eye sight is very poor. Usually he wears a pair of 7 diopters. And that’s enough for his eyes. Recently, he said that he feel the glasses seems to not suit him anymore, sometimes he feels blurred when he look far away. So he asked me to accompany him to go to the doctor to have the eyes examined.
So the next Sunday, I accompanied him to go to the doctor. After the test, the doctor said that with the growing of the age, the condition of the eyes is becoming more complicated. When one look near, he or she would find it hard to see clearly, while look at things in distance, they still have problems. People become a combination of myopia and hypermetropia. This is called presbyopia. In this situation, the doctor advises my father to buy a pair of bifocal eyeglasses, which is designed for people with presbyopia. Bifocal eyeglass is a kind of glasses with different prescriptions in different parts of the lenses. For example, in the upper side of the glasses, the prescription is 3 diopters, while in the down side of the glasses, it may be 1 diopters. The difference in prescription may satisfy people who need different requests at different distance.
Instantly, we go home and search relevant information about bifocal eyeglasses. There is a large amount of information about it. And through careful observation we finally focused on some shops. And we separately clicked in the relevant hyperlinks and go on our careful study. Through the feedbacks of wearers, we know that there will be an adapting process. The common glasses only have single prescription while bifocal eyeglasses have two. So when one see things form different section of the glasses, the eyes themselves should adjust to the glasses, sometimes the wearers will feel dizzy. In the process of study, we came to know a different kind of glasses called progressive glasses. This kind of glasses is similar to the bifocal eyeglasses. Rather than two prescriptions, progressive glasses have many prescriptions in one pair of glasses. The prescriptions are arranged in a progressive order that is the reason of its name. So a single pair of glasses can satisfy people’s different demands, ranging from shortsighted to farsighted.
Finally, we decided to buy a pair of prescription glasses in an online shop called glassesshop.com. It has its own progressive section so we think it may be formal and reliable. Furthermore, the glasses sold by them are quite cheap since it’s the first time we buy progressive glasses and we should take care. We hold the opinion that if we take this purchase as an experiment so we should not take too much risk. If it fails, it did not take us much money, whereas it successes, we will be too happy to have done it.
The result turns to be satisfactory and we are quite satisfied by its after service. They take close eye on the feedback of my father and give professional suggestion to us. They are very good!
