Why Should You Choose Progressive Lenses Over Bifocals And Trifocals

November 28th, 2011

The discussion and debates surrounding the topic of whether progressive lenses should be chosen over their bifocal and trifocal counterparts have been going on since like forever ago. While the two groups of people following them separately have perfect enough arguments and reasonings, it seems that the ones who favor progressive lenses are gradually taking the upper hand. Let’s herewith hear their arguments and decide for ourselves whether they make sense.

First of all, these eloquent fine debaters would say, lenses of progressive glasses provide better visions than bifocals and trifocals do. This is a statement with much truth in, basically in three aspects. First, progressive lenses provide more precise powers. Bifocals and trifocals, as already revealed by their names, only have two or three different powers blended onto the same lenses, which means one can only get clear vision for two or three ranges. For most people this might come as a huge harassment since real life experience tells us that only two or three powers don’t even come near as enough for our daily uses. Progressive lenses, on the other hand, provide a gradual progression of prescription powers, with which almost any vision need could be met. Secondly and probably the most importantly, progressive lenses spare their wearers off the nettling experience of image jump, in which sudden changes of powers across the separating lines could cause distortion to the image and nausea and other reaction to the wearer. Progressive lenses, with the ingenious design of gradual progression of powers, offer wearers a natural smooth view that resemble one that you get with your natural eyes. Precise powers and natural view, it can’t be to much of a mistake to say that progressive lenses are the ones with better vision.

Another argument that keeps coming on the lips of those progressive lenses advocates has to do with aesthetics. As is known to all, bifocal and trifocal lenses have these annoying visible lines that give away the wearers’ age in no time. Most people have scruples with bifocals due to this defect. With progressive lenses, they don’t have to worry. Rid of the nettling lines, progressive lenses immediate create a youthful and energetic vibe to the faces of the wearer.

Progressive Lenses Are The Ideal Lenses For Eye Glasses

November 4th, 2011

Eyeglasses and progressive lenses are the perfect match. They fit for each other not only functionally but also aesthetically. For eyeglasses, the type of glasses that have certain prescription powers so as to meet particular vision correction needs, the lenses choice is surprisingly rich. There are the single vision lenses, the most common one around, the bifocals and trifocals and the progressives. Out of the three, the latter two can then be classified as a type, the multi vision lenses. The difference of them from the single vision ones is, of course, the number of prescription powers featured. While single vision lenses are still the predominating force in the optical industry, there do exist a huge demand for multi vision lenses, for the number of people with more than one particular refractive error is growing rapidly. Those people want their eyeglasses with more than one prescription powers so their multi vision correction needs can be cured are certainly in preference of such glasses.

As for the advantages lenses of progressive glasses have over bifocals and trifocals, its pretty simple. Most of those who wear bifocals are over the age of 40 and have developed presbyopia, as a result, the visible lines on the lenses have long been regarded as a telltale sign of the wearers’ age. Progressive lenses, with their uniquely advanced design, solve the problem once and for all. Because the prescription powers on the lenses increase gradually instead of suddenly jump to a new level, there’s no meeting point of two utterly different parts of lenses, hence no visible lines. This is hugely beneficial aesthetically in that the wearers of such glasses will no longer be immediately recognized as the one who’s over 40 in a crowd. With such glasses, they look just as young as those dynamic youngsters.

Having established that progressive lenses are the best lenses out there for eyeglasses wearers, you may wonder where to get them. While every optical store has their stocks of such glasses, online retailing websites are the places where you can get the best bargains. So, once you’ve made up your mind about these progressives, why not swing over to some professional websites to check out some of the most worthy and cost effective glasses on the planet.

Progressive Lenses and Frames Prove Immensely Helpful

October 23rd, 2011

For those suffering from presbyopia, a pair of eyeglasses made from progressive lenses and frames proves immensely helpful and useful. As age presses ahead, many adults in their advanced age, or even middle age, are harassed by the vision problem. And bifocal or trifocal eyeglasses are not enough to provide sound protection and correction for their deteriorating eyesight. They get bogged down in the dilemma between clear vision and proper vision correction. Now a pair of eyeglasses made from progressive lenses and frames will come to your rescue and eliminate your dilemma once and for all.

Progressive lenses are quite different from bifocal and trifocal lenses in that progressive ones are justified to be called multifocal, thanks to the gradient of lens powers blended in a single lens. With different degrees of magnification from the top to the bottom part of lens, respectively indicative of minimum to maximum magnifying power, the progressive lenses are fully and readily armed to offer all-around vision support. Wearing pogressive eyeglasses, you can easily descry the objects no matter in near, intermediate, or far distance. All remains for you to do is that you should tilt or lean your head to focus your eye to the exact portion of lens which provides corresponding magnifying power in accordance with the distance of the objects. There is another merit that is worth your credit, that is, progressive lenses are free from the defect of image jump which usually plagues wearers of bifocal and trifocal glasses. Put it another way, progressive lenses are characterized by seamless and smooth transition between different lens powers. The gradient of lens powers goes smooth from one degree to another, without resulting in the uncomfortable and uneasy viewing experience. This strength enables wearers to see things in a much smoother and easier fashion.

On account of the comprehensive lens powers blended into one single lens, the traditional frames are designed or customized in a fairly large size in order to accommodate the area of focus of progressive lenses. This may make the frames very unpleasing to the eye. But as modern technology advances, many progressive lenses manufacturers had come up with a method to overcome this problem by means of inventing the “short corridor” progressive lenses with compact designs. This means it will provide larger reading zones and make it compatible with a lot of stylish and trendy and smaller frames. Undoubtedly it attaches so great a touch of fashion to the progressive lenses.

Having taking into account the abovementioned facts about progressives and lenses, you must have gained a fairly good and clear understanding of them. So next time do not hesitate to lay your hands on them, for they are quite worthy of your money.

What’s difference between average reading lenses and progressive lenses
Compared with average reading lenses, there several apparent characteristics of progressive lenses. In fact, progressive lenses are well-known for a gradient of prescription powers, which means the gradient starts at the distance power at the top and reaches to the maximum added power for near vision at the bottom gradually. Due to this special feature of progressive lenses, they enable people, especially elder group over 40 years old, to see clearly at varying distances with only slight tilts of their heads and their eyes. To be specific, not only do progressive lenses make accommodations between varying distance prescriptions effortless and correction of multiple refractive errors possible with just one lens, but also the intermediate in between and the close up at the bottom fits the natural positions required for respective vision tasks perfectly.

And if they want to relax with a book, they only need to see through the most added area at the bottom. Progressive lenses make accommodations between varying distance prescriptions effortless and correction of multiple refractive errors possible with just one lens. Aside from that, the design of having the distance vision area on the top, the intermediate in between and the close up at the bottom fits perfectly the natural positions required for respective vision tasks.

Speaking of correcting multiple refractive errors, there are quite a number of types of lenses that can pull it off, among which most notably bifocals an trifocals. What’s different about progressive lenses is that they do it with comfort and delicacy. Thanks to its gradient of prescription powers, progressive lenses avoid the discontinuities( A.K.K image jump) in visual field created by many of it bifocal and trifocal counterparts. With these lenses, the wearer will be spared from the discomfort caused by sudden changes in prescriptions when their eyes move across the sharply defined boundaries between different segments on lenses of bifocals and trifocals. A more natural and continued vision field is created, for the ease and health of the wear’s eyes.

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 18th 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.

Progressive eyeglasses lenses are now becoming some of the most favorable products for wearers. Those lenses are really unique in many aspects, and can help overcome many demerits in conventional lined lenses. And there are two main forms of those lenses, namely bifocal and trifocal. Here is some detailed information about the two lenses.

They find that those advanced lenses are really ideal for them. They have both those merits in progressive bifocals and some their own advantages. Usually, wearers will feel much comfortable with them, for the vision changes are very natural. Still, these lenses can also ensure people enjoy great vision clarity. Or some wearers think they feel no lenses on their faces with them.

In fact, the result of progressive Vs trifocal lenses can reveal much great difference between the two. They are totally different in solving eye problems and other compilations in common glasses. The former one can also provide great comfort to wearers at any time with great vision clarity, whereas the later has some shortcomings.

In conclusion, progressive spectacles lenses are much better than ordinary lined lenses. And it is a good idea to choose them at any time, for more and more achievements are now made on them in terms of both functions and designs.

Still, those sunglasses are really very nice to look at, keeping with the latest fashion in the industry.

However, regular wearers of those lenses find that some progressive lenses problems can never be avoided at any time. This is because those problems are some inseparable parts of those lenses. One of the greatest problems is almost all wearers have to spend sometime adapting those lenses. And the adapting time varies a lot amid people of different groups. For instance, younger people may spend less time than those older ones; those who seldom wear glasses may spend less time than those regular wearers of other glasses.

In addition, how much do progressive lenses cost is also a frequently asked question by many consumers. Those lenses are really much expensive than other ordinary glasses.
