Introduction of Several Bifocals

March 31st, 2010 by Jean Caster No comments »

As one of the oldest forms of varifocal glasses, bifocals can still maintain their vitality all the more. Then, some people may ask- what are varifocal glasses? Varifocal glasses refer to those glasses that have more than one focuses in one lens- some have two, others have three or more. Bifocals are just such typical glasses with two focuses. Some people may think that bifocals should retreat from their markets, for there are some much advanced glasses- trifocals and progressive glasses. In fact, it is not the case because more and more innovations are now made on them.

Bifocal safety glasses are just one of the most important forms of bifocals. Those glasses are bettered on the basis of conventional bifocals and can assure wearers enjoy great security with them. In particular, if people often expose their eyes to the sun light, their eyes may become injured as a result. Correspondingly, those safety glasses can make sure that wearers can enjoy ideal vision clarity without worrying about any potential damages. Those glasses are now available by almost all famous glasses manufacturers. For example, Lowes, one of the world’s top glasses makers, manufactures and provides the first-class bifocal safety glasses to consumers of all walks of life. Therefore, people may have a try on their products- bifocal safety glasses Lowes.

There are still bifocal glasses for sports use. Those glasses are specially designed for sportsmen and fans. Generally, wearers will have endured the pain caused by glares and other unwanted lights. With those glasses, some wanted lights will be highlighted and other unwanted lights will be filtered. In a word, sportsmen can have much better performance with them. And it can be easily to explain the reason why so many people love to wear bifocal sport glasses.

In addition, there are also bifocal sunglasses of different forms and types. Of which, bifocal reading sunglasses polarized are very outstanding. They are some of the best alternatives for people who love to read under sun lights or around any places with great glares. They can block any harmful radiations and rays in the sun lights and can also filter out any glares reflected by glass or water. So, some people who love to fish also wear such sunglasses.

Of course, there are also many other unique bifocals, like progressive bifocals, etc. And this can help explain why those glasses are still very popular among people.

Why Are Multi-focal Lenses So Nice to Wear?

March 30th, 2010 by Scott Mozayeni No comments »

There are many forms of varifocal spectacles, like Varifocal spectacles lenses, Varifocal sunglasses, cheap varifocal contact lenses, etc. They have benefited a lot of people, though there are some minor varifocal spectacles problems.

In the past, people often and have to wear single vision lenses, due to backward technology in the industry. However, as many innovations are made, some multi-focal lenses are available in the market. They are also called varifocal spectacles. Generally those spectacles have many derived forms. Here are some of them.

Varifocal spectacles lenses are the main part of those spectacles. They can be used to replace the same frame if people like. And many wearers who love to wear glass lenses of different styles and designs often buy several pairs of such lenses. Doing so can help them save a lot of money, and maintain personal images and tastes. In particular, more and more achievements are gained on those lenses.

Varifocal sunglasses are other forms of those spectacles. Sunglasses of this type are combination of function and fashion. That’s to say, they can be used for vision correction and accessories. In summer, those sunglasses are good alternatives for people who are in need of varifocal glasses if they often go outdoors. However, many people are confronted by the fact that varifocal glasses are very expensive, let alone varifocal sunglasses. Fortunately, there are some retailers who have considered the needs of consumers from different social strata. They will sell some of those sunglasses at very low price. Usually, people can get those cheap varifocal sunglasses from online vendors or some particular optical shops. Of course, their quality is the same as other expensive ones.

Still, there are also contacts with multi-focuses. Those lenses are very popular among people who often care a lot about their personal images. And those lenses are also very good choices for some sportsmen. However, contact lenses are among some of the most expensive products in the industry, needless to say multi-focal contacts. But this does not mean those lenses can only be worn by some rich people. Luckily, cheap varifocal contact lenses are also available in some shops. Their cheapness can benefit those who do not want to wear glasses.

It is no denying that some varifocal spectacles problems can never be avoided, be they systematic or unsystematic. If people can consult with their eye doctors and care about some related maintenances, such problems can be reduced to some extent.

Astigmatism and Bifocal lenses

March 30th, 2010 by Scott Mozayeni No comments »

Bifocal lenses are proved to be very useful in curing some particular eye problems. Of which, astigmatism can be effectively by them.

Astigmatism, one of the most common eye problems among glasses wearers, has caused a lot of troubles to sufferers. Sufferers of this disease always have blurred vision, for the images of any object can not be directly and accurately projected on the retina. Just because of this, they will have to endure double vision that may cause dizziness if such symptom can not be treated. Generally, based on the causes, astigmatism can be fallen into two sorts, namely, regular and irregular astigmatism. However, any one of the two types is caused by the damage or deformation in cornea or lens.

As so many troubles will be caused by this problem, many sufferers want to get rid of it completely. People have tried every possible effort to tackle it since the problem occurs. And now, there is a very effective ways for it- Wearing bifocal lens for astigmatism is a well-known solution. Here is some specific information about it.

Bifocal lenses are some of the best alternatives to cure astigmatism. Maybe the bifocal lenses history is firmly related to astigmatism. The data has it that the history of those lenses is much shorter that ordinary lenses, only about two and a half centuries. The first bifocal lens inventor is legally said to be Benjamin Franklin. He might be one of the sufferers of astigmatism when he was old. Because he was such a wise and creative man that he had found the solution ultimately. Or he might be a sufferer of other eye problems, as presbyopia, and he made such lenses that were also very useful in treating astigmatism. Anyway, bifocal lenses are very nice alternative to deal with astigmatism.

As for bifocal lens types, there are lined bifocals and no-lined bifocals. This first type is the oldest and commonest member in the family. There is an evident division line in the middle of the lenses. The second type is the latest member in the family. As no such division can be found in those lenses, they are also called progressive bifocals at the same time. And the two types are very good alternatives for people with astigmatism.

All in all, astigmatism can be successfully cured by wearing bifocal lens for astigmatism, and every sufferer of this problem may have a try.

What to Do If We Have Presbyopia and Other Near-vision Problems Simultaneously?

March 29th, 2010 by Jean Caster No comments »

Eye is such one of the most important organs for our human beings that we should care it a lot. However, each of us will get old as time goes on. And some unavoidable eye problems may occur as a result. For example, presbyopia is an eye problem that often strikes people who are over forty. And for some of us who have nearsighted or astigmatism, etc. they may suffer a lot when they are over forty.

Luckily, there are two methods to tackle such condition- wearing glasses and receiving surgery.

In fact, ordinary glasses are useless in solving those eye problems. And one of the best alternatives is bifocal lens. In fact, bifocal lenses are also called bifocal lenses Benjamin Franklin. This is because Bifocal lens history is firmly connected with him.  Almost two and a half centuries have passed and many innovations are made on it since bifocal lens was created by Benjamin Franklin. Bifocals are some of the most widely used reading glasses for many aged people or people of other age group.  Most of such lenses are lined, for they are combined by two different cut lenses. And now, there are some no-lined bifocal lenses, also called progressive bifocals. Those lenses are much advanced than conventional bifocals, for there is no radical vision change. Wearers will feel no lenses on their face, as those lenses can provide natural vision. Therefore, most people tend to wear progressive bifocals. And Facts have proved that many people have had their eye problems solved by wearing bifocals, be conventional bifocal lenses or progressive bifocals.

Or in some other cases, like the problems are very serious or the patients do not want to wear glasses, eye surgeries are better alternatives. Among all those eye surgeries, receiving bifocal lens implant is rather good. During this process, only some small incision will be made and patients will not suffer from any great pain. After the surgery, patient will find that they have new eyes, for their eye problems are cured successfully. However, surgery will cost much than ordinary methods.

Keep in mind, we should consult with our eye doctors, no matter which method we choose. If we can do as our doctors suggest, we can get very good results in solving those horrible eye problems.

Bifocals for Reading- So Many Members

March 29th, 2010 by Jean Caster No comments »

Bifocals are some of the most widely used devices for vision correction. And they are also sometimes the symbols of fashion. But the purpose for reading is of the greatest importance. Therefore, many bifocals that are firmly related to reading come into market. Here are some forms of those glasses.

Bifocal readers are some of the most conventional forms. Those glasses can help wearers a lot if they have some problems in seeing minor objects. The can be used as magnifying glasses sometimes. Generally, according to the patients’ needs, the prescription varies a lot. For example, some are in need of larger power and other need smaller power; some are in need of +1.5, while other +2.0 power magnification. In this sense, those readers can help wearers see any objects very clearly if accurately prescribed.

Still, there are also some tined bifocals for reading.

Bifocal reader sunglasses are tinted bifocals. Those glasses can be used both as reader and sunglasses at the same time. And they are some of the most beloved products among young people in summer. Functionally, they can magnify what people see; they can help protect wearers’ eyes from being damaged by any harmful rays and radiations in the sunlight. Those glasses can also be symbols of fashion in most cases. Henceforth, some people always think how cool it would be if reading with those sunglasses under the sun.

Bifocal reading sunglasses are also very nice alternatives for those who often read in the sunlight. Those sunglasses are suitable for people who can see minor objects clearly and it is not needed for them to magnify any objects. Like the reader sunglasses, those sunglasses can present wearers great glamour.

It is true that those glasses are really very nice to have on. And of course, sometimes problems may also occur. Therefore, people should be careful about their eyes and their glasses. The vision care of bifocal reading glasses is really very important. And wearers are suggested to do two things. One is often consult with their eye doctors on their eye problems and something about their glasses. Another is to nurture very good habits in eye caring and glasses maintaining. By and large, if wearers can follow the aforesaid two points, they can enjoy very nice eye health and the longevity of their glasses can also be prolonged.

An Overview on Progressive Lenses

March 28th, 2010 by Randa Nahl No comments »

It is true that progressive glasses are the most important devices for some eye-problem-struck people. However, the most important parts in those glasses are lenses. Therefore, the evolution of progressive glasses is also the upgrading of lenses. Here is some information about progressive lenses reviews that are often discussed by most people. Here are some of those points.

When it comes to some products, people will firstly think of their brands. Therefore, the first point is about progressive lenses brands. There are many brands for almost all products, and progressive lenses are no exception. Generally, their brands cover from low-end to high-end. That’s to say, some of those lenses are for ordinary wearers, whereas others are only for people of upper class. Essilor, Hoya, Kodak，Shamir，Sola, and so forth are some of the most reputable brands for progressive lenses. Each one of them has its own targeted consumers. And consumers of particular group may just buy those fit them most. Therefore, those brands can work in complementation.

Another important factor that may influence people’s purchasing- cost. And many people want to know how much do progressive lenses cost. In fact, there is no exact answer for this question. However, there is something that is firmly related to it. Compared to ordinary lenses or bifocal or trifocal lenses, progressive lenses are much expensive in the same glasses shop. This is because progressive lenses are in need of much accurate prescription and manufacturing and more efforts will be spent as a result. But if from different vendors or retailers, those lenses may be cheaper than ordinary lenses. For example, progressive lenses from online vendors cost less than those from real optical stores.

However, wearers may be troubled and confused by some progressive lenses problems. Those problems might happen only in those lenses. For example, any discrepancy in prescription will directly lead to mistakes in the lenses, and many consumers have experienced this when they purchase online, but fail provide their latest eye prescriptions.

Ultimately, progressive lenses can be obtained from various channels. The most common place to get them is real optical store; and the most popular place is online shop. However, the latter channel is money-saving, but with more accidents.

In a word, progressive glasses are really very important, so are progressive lenses. And people are suggested to know more about both of them.

The untrue perception of eye vision

March 27th, 2010 by Stephen Simon No comments »

Our only pair of eyes is the organ for vision, through which we can see the world. Scientists found that most of the perceptions and ideas passed down from our parents about eye vision correlations are wrong. Let’s look at some of them.

The first misperception is that wearing eyeglasses can meanwhile worsen your eye vision as time goes on. This is because, before wearing glasses, you get used to the blurry world around you. After wearing, you see the clearer surroundings, after that you get accustomed to the new world. Now if you take away the glasses from you after a period of time, you will feel the world is not the same as what was before your wearing glasses. This is the change of your perception, not the eye vision itself. Your vision and eyes are the same actually.

The second misperception is that extended use of eyes will damage and worsen our vision. This was told by our parents and teachers since childhood, but this perception about eye vision was believed to be untrue either. Eyes fatigue may occur after reading books or watching TV for prolonged hours, but eyes fatigue is not going to worsen your eye vision. Scientists say eyes are meant to be used, even overused sometimes.

Thirdly, all of us used to do the eye exercise for many years in the school and at home, which was thought to be useful and effective in preventing and curbing the progression of nearsightedness and improve the eye vision. A survey conducted in America concluded that there is no evidence showing relations between eye exercise and the improvement of vision of eyes.

Scientists further explained that the eye vision is a mechanism of heredity. There may be other factors which influence people’s eye vision, but no strong causation has been found.

Though there are so many misperceptions, it is always wise to visit a vision optometry in your local community and have your eyes vision checked and prescribe eyeglasses when necessary. Periodic visiting in vision optometry is necessary to ensure that you can always see clear of the world.

Trifocal Lenses -Unregretful Alternatives for Glasses Wearers

March 27th, 2010 by Stephen Simon No comments »

During the several hundreds of years, people have to wear single vision glasses before the emergence of the first bifocals. Bifocals are some of the earliest varifocal lenses. As their names indicate, those lenses have more than one vision focuses on one lens. They have benefited people who have both near vision and far vision eye problems simultaneously. Among all those lenses, trifocals are most typical.

Trifocal lenses, as people can know from their names, are lenses with three focuses- focuses for far vision, middle vision and nearby vision respectively. Then, which part in the lenses is responsible for a certain vision? Looking from their structure, the top part is for far vision, the middle for intermediate vision and the lower for nearby vision. Therefore, people can see clearly of any objects within their corresponding vision areas. The greatest advantages in those lenses are wearers can enjoy more comfort than by other lined glasses. However, there are still some demerits on them. For example, wearers will have to spend sometime adapting them; they may sometimes suffer from visual complications, due to the structure of those lenses. Of course, those troubles are rare and minor.

As for these who want to buy those nice multi-focal lenses, how much do they cost is really very important. Compared to other single vision lenses, trifocal lenses cost a little more. For example, if the conventional lenses are averaged $200 in real optical stores, those multi-focal lenses will cost about $300 on average there. However, this does not mean wearers will have to spend a lot of money on them. There are some cheap ones in certain shops through particular channels. Trifocal lenses at those places are much cheaper than other ordinary retailers with guaranteed quality and can be afforded by many wearers.

Among all those purchasing channels, buying trifocal lenses online is really very fascinating for many people, due to several reasons. One is those lenses can be obtained at very low cost; another is buyers just need to click their mouse if they want to buy; products from online vendors are also guaranteed in quality, etc.

In a world, those unique lenses are really very ideal choices for people with aforesaid eye problems both functionally and economically. Just be quick and get them.
