April 13th, 2010

People with certain eye problems, like astigmatism, presbyopia, are in need of multi-focal glasses. And the first multi-focal glasses, bifocals, were invented almost two and a half centuries ago. But during that period of time, great achievements are made in this field. People in now days can find that there are various sorts of multi-focal glasses and some of which are made by combining together with other types. Among which, trifocal sunglasses are just such typical examples. Those sunglasses are, to some extent, some of the best products for people with the aforesaid eye problems. And wearers can also enjoy the happiness of great vision clarity and comfort life with them. Why? This can be explained from several perspectives- here are they.

What’s more, some of the most important features on sunglasses can also be found on trifocal sunglasses. It is said that eyes with problems are in need of more care and protection. Therefore, trifocal sunglasses are not only made from tinted lenses, but with lenses of particular functions. Those lenses are very nice at combating explosive that may cause serious damages to eyes once the lenses are broken. Still, trifocal sunglasses can protect wearers’ eyes from being injured by harmful rays from sun lights or in our daily lives. For example, UV rays can be filtered out by them; some glares reflected by other objects can also be blocked; dust that may lead to eye infections can also be kept off, etc. Therefore, those sunglasses are very popular among people of certain group- people who love to read under sun lights can wear them; people who love to do outdoor sports can choose them, etc.

From the perspective of cost, trifocal sunglasses are also affordable for almost all people, no matter how much they earn.

However, those eye-disease-struck people also want to have a try. Later, there are some prescription sunglasses in the market- people with some common eye problems, like myopia, farsightedness, etc, can also wear sunglasses. But no one has ever thought that people who are in need of bifocals or trifocals can wear sunglasses- those problems are really very hard to deal with. Subsequently, some great achievements are made and progressive sunglasses come into market, which are much advanced than conventional bifocal or trifocal sunglasses. Those unique sunglasses are very popular among people of particular groups.

A Panorama of Bifocal Eyeglasses

April 12th, 2010

Among all the great inventions in the history of human being, eyeglasses are included. According to some data, the first modern-alike eyeglasses did not come into being until the 13^th century in Italy. Since then, eyeglasses started their course of enhancing vision. However, people gradually found that some eye problems could not be solved by ordinary glasses, for they might have more than one eye diseases simultaneously. But the practicable solution for such problem did not become possible till the emergence of bifocal eyeglasses.

Bifocal eyeglasses, as their names indicate, are eyeglasses that have two focuses. For each lenses, there are two parts, say, the top part and the lower part. The former part is for distance vision and the later one is for nearby vision. Therefore, one can look at the top part if he wants to look afar; and look at the lower part if reads. Generally, the former one is much wider than the later one. This is because much wider vision area is needed when one looks afar. Therefore, there is an invisible vision arch in the lenses. Due to their unique merits, bifocal eyeglasses can effectively solve eye problems like, presbyopia, astigmatism, myopia, etc. that may occur at the same.

However, the invention of bifocal eyeglasses is rather complicated and they do not appear till the late18th century. Here is some information about the history.

In fact, the history of bifocal eyeglasses is a legend. Although who have invented bifocal eyeglasses is still in controversy, most people deem Benjamin Franklin as the only legal inventor. According to bifocal glasses Wiki, Benjamin Franklin had some problems in reading when he was old. However, he was such a creative man that he decided to solve them by making some glasses. One day, he found his problems can be treated by overlapping two lenses, namely, one is for near vision, and another is for far vision. Then, he began to embed the two lenses in one frame. And the ultimate result was-with those newly created glasses he could see clearly of objects afar after reading for sometime. It might be possible that Franklin is not the first inventor of bifocals, but he should be the first to wear them.

The bifocal eyeglasses created by Franklin are not as nice as people can now use. They are roughly made, partly due to then backward technology. However, as some innovations are made in the industry, bifocals are also perfected all the more. Only two century are passed away, bifocals in nowadays are really very practical and nice in solving the aforesaid eye problems. For example, people will seldom complain of their eye problems with personalized bifocal eyeglasses. Or to some extent, those glasses can highlight their personal tastes and elegance.

Professionals in the industry find there are still many things to do with bifocal eyeglasses. In addition to assimilating some fashionable elements in their designs and products, they also spare no efforts in strengthening their functions of vision correction. For example, most of the bifocals are lined glasses, and they have prompted some no-lined bifocals recently. Those newly upgraded lenses have bettered people’s lives greatly.

It is no denying that with the development of technology, more achievements will be scored in bifocals. Here is a promising and bright future.

What Do You Know About Some Common Multi-focal Lenses?

April 12th, 2010

This history of glasses lenses can be dated back to more than eight centuries ago. However, those lenses we often use till now are almost single vision and the lenses with multiple focuses did not come into being until the emergence of bifocals. It was the 18^th century that witnessed the appearance of the first bifocal lenses. And who is the first bifocal lens inventor? Till now, the universally recognized inventor is Benjamin Franklin, one of the most reputable state men in then US. He found it was impossible for him to read or see other objects with ordinary single vision lenses (he may have both Presbyopia and near vision problems at the same time). He then tried many methods to solve those problems by overlapping two different lenses. And the results prove to be practical.

Theoretically, multi-focal lenses, also called varifocal lenses, have more than one vision areas comparing to ordinary lenses. Bifocals listed above are just such typical example, with two focuses. In fact, there are still some other multi-focal lenses that can be found in optical stores, in addition to bifocals.

Trifocals, also called trifocal lenses, are much advanced products than bifocals. They have three vision areas in the same lenses, namely, near, intermediate and far vision areas. They can provide wearers with much greater comfort while they have to look at objects of different distance.

However, there is a disadvantage in both bifocals and trifocals- there is an evident division line among each vision areas. Because eyes have to endure the pain of transmitting from one area to another, some wearers can not withstand such radical vision changes. Therefore, much advanced lenses are needed.

Therefore, the coming of progressive lenses has satisfied people’s demands. Those lenses are really multi-focal, for the transition among any vision area is very natural and no aforesaid lines can be detected on them. So, wearers of such lenses will never suffer from pain caused by radical vision changes. And the result is more and more people love to wear those lenses. Moreover, progressive lenses often come together with bifocals and trifocals.

Multi-focal lenses are always in the process of evolution, through which more and more achievements are scored.
