Progressive eyeglasses differ from traditional reading glasses, bifocals or trifocals in lens design. While those three types provide one to three lens powers in a single lens, progressive spectacles incorporate a set of different powers in their lenses. The majority of presbyopic patients may have known this functional difference between other forms of multifocal reading glasses and progressive glasses. However, there may be fewer people know that progressive glasses frames can also differ from the frames of other reading glasses. This saying is well founded. In fact, even progressive glasses users want to wear attractive frames with fashionable styles. And progressive eyeglass frames manufacturers should consider all traditional factors that are involved in regular types of glasses.

Frame size is the most critical factor that may differentiate progressive glasses from other forms of reading glasses. First let’s discuss the frame size of regular reading glasses, bifocal and trifocals. Traditional reading glasses all take use of single vision lenses, so that lens design will not impose extra requirement on frame size. When it comes to bifocal lenses or trifocal lenses, there is more than one power in a single lens. Some people may get worried that the frame should be large enough to host large lenses which will provide enough visual field at each part. In fact, two or three focal points can be easily arranged in a small frame, with modern lens technologies.

The task is slightly harder when opticians try to insert progressive lenses into a small frame. The reason is that a progressive lens comes with a gradient of increasing powers. If the frame is too small, the reading portion of the lens may become particularly narrow and cause uncomfortable reading experience. This is because progressive lenses should be cut to a size that is compatible with the small frame. Without the availability of “short corridor” progressive lenses, progressive glasses frames have to be relative large if the wearer expects normal reading aid. However, modern lens technologies have made it possible to take use of “short corridor” progressive lenses and specialty lenses with customized reading or intermediate portion.

C: Progressive glasses frames were at a time larger than bifocal frames or trifocal frames. The development of “short corridor” progressive lenses and customized lenses makes presbyopic individuals to enjoy those small frames.

People who have experience of ordering some goods on the Internet know probably some of the benefits offered by this source. For example, it is needless for the buyers to leave their homes or offices. Simple enough, a few clicks of the mouse can make all things done. Eyeglass products are also widely available online now. Most people tender to get similar benefits and try to purchase spectacles from online retailers. Well, it is ok to get ordinary eyeglasses like regular prescription eyeglasses, sunglasses, goggles and so on. However, when it comes to bifocal glasses online, additional care is absolutely necessary.

Online retailers will certainly feel additional challenge when they try to provide bifocal reading glasses for customers through the Internet. The reason is that fitting these bifocal lenses is really an intricate process which involves basically an additional prescription power. In fact, this is the similar case in trifocal eyeglasses and progressive eyeglasses. These three forms all belong to multifocal eyeglasses. This term suggests an obvious point that more than one power should be fitted into a single lens. This involves surely more skill requirements on an optician or an optometrist. Since the purchaser is not present, it is relatively harder for an optician or optometrist at the side of an online retailer to get the target eyes perfectly fitted. This is why most sites shy away from offering bifocal glasses online.

Another challenge associated with purchasing online bifocal reading glasses is that now there are lots of special-purpose designs. For instance, there are reading segments in different shapes that can be added into a primary lens. D segment, round segment and rectangle segment are possible customized styles. These customized bifocal reading glasses require certainly extra measurements of the customer’s eyes. Even for those retailers courageous enough to provide bifocal glasses online, an in-depth discussion with the customer is indispensible.

C: Bifocal glasses online involve additional measurements and in-depth discussion between the two sides. Presbyopic patients should take additional care before deciding to access this source.

Progressive eyeglasses have been benefiting and satisfying a great number of presbyopic patients all along its history. Compared with bifocal reading glasses and trifocal reading spectacles, progressive glasses made of progressive addition lenses make some significant improvements. For instance, the bothersome problem of image jump can be completely eliminated by using progressive spectacles. However, there is still an inherent problem or shortcoming that will naturally be caused by progressive power lenses. Like other forms of multifocal reading glasses, the problem of peripheral vision loss is to some degrees inevitable. This can not be completely avoided. In fact, it is not objective to singly sing the praises of progressive lenses’ unique and sophisticated design.

It is true that the power gradient of a progressive lens can prevent the users from getting visual fluctuation or experiencing image jump that will probably occur in bifocal or trifocal eyeglasses. Progressive eyeglasses will never cause this problem. By molding a wide range of lens powers into a single lens, it is quite significant while evaluating its benefit of bringing comfortable power transition. Putting aside the non-functional benefit of bringing more attractive lens appearance, these functional advantages mentioned above should help progressive glasses gain greater customer acceptance. However, the truth is that nothing in this world is flawless. Progressive reading spectacles are not exceptional in this case.

When the gradient of increasing lens power enables the wearer to see clearly at all distances, including the near, the intermediate and the distance, peripheral vision loss is an inherent side effect because of the narrow vertical range of undistorted vision. To some extent, progressive eyeglasses are born to be associated with this problem. It is easy to understand that each part of the lens responsible for one vision range becomes narrower. While this problem happens to bifocals and trifocals slightly, it is more seriously linked with progressive spectacles. Taking the intermediate vision zone for example, some wearers of progressive glasses can not even see more than 25% of a computer monitor. And they have to move the head from side to side in order to get a comprehensive view of the screen and the content on it. An approach to make a compromise is to use tailored progressive lenses especially for computer work.

C: Progressive eyeglasses were born to cause an inherent side effect or shortcoming, peripheral vision loss. This problem is sometimes inevitable because the vertical range of undistorted vision becomes narrower.

A convincing testimony to the technological improvements in the eyewear industry is that progressive eye glasses succeeded well the traditional bifocal reading glasses and trifocal glasses. As a later comer, progressive glasses are supposed to offer more benefits associated with visual correction. This is absolutely true. The inventors of progressive eyeglass lenses did this work just with clear mind of making progression. Compared with conventional bifocal reading glasses or trifocal eyeglasses, progressive spectacles do have some advantages which are brought by the unique and complicated lens design. The most noticeable breakthrough made by progressive lenses is that a gradient of increasing prescription lowers could be incorporated into a single lens.

Such a powerful lens is incomparable. This is because a bifocal lens has a universal design with only two powers and a trifocal lens only adds an additional power. Thus, the functionality of vision correction enabled by progressive eye glasses is also superior to that of either bifocal glasses or trifocals. It is true that people can get visual aids at near, intermediate and distance ranges from a pair of trifocal spectacles. And the extra visual help at the intermediate zone marks the difference between bifocals and trifocals. However, objects within all distances can be controlled by a pair of progressive spectacles. Compared with bifocals and trifocals, progressive reading glasses come with a smoother power transition.

Another advantage of progressive eye glasses is old-age-related. Both bifocal and trifocal reading glasses are obviously associated with “old age” because they have visible segments or lines on the lens surface. Progressive lenses have never these “age-telling” lines or segments. For a certain group of people especially female ones, it is unpleasant to let others know their age. In this case, progressive eyeglasses are more cosmetically attractive. Most wearers can adjust to the additional lens power by tilting the head to sight through the appropriate part of the vertical progression.

C: Progressive eye glasses as a later comer have some valuable advantages over traditional bifocal reading glasses and trifocals. They provide a smoother power transition and more cosmetically attractive look.

Of course the colour of your skin, hair and eyes can also affect your decision.Skin tone is often a primary factor in choosing the right frame colour. All tones fall into two different colour bases blue which is cool or yellow which is warm. A cool complexion has blue or pink hues while a warm complexion has a yellow or peaches and cream colour. Eye colour is usually a secondary reason when choosing your glasses because of the wide range in eye colours. With blue eyes for example, they can range from violet right through to pale blue in colour. Brown eyes can range fron a light shade which is cool all the way to almost black that is warm in colour. Hair colour should also be considered either cool or warm. Strawberry blond, gray, white and light brown are cool colours. While golden blond, flat black brown and red hair are warmer colours. Once you determine whether you are warm or cool in colour you will be able to find the right frame to suit your needs. For cool colourings go for frames that are black, dark brown even plum or magenta also a dark turquoise would work really well.

To choose the right glasses for a round face, you should try angular narrow glasses to lengthen the shape of your face and look for glasses that have a wider structure like rectangular shape frames. The oval face is thought to be the perfect face shape due to the equal proportions. To keep the balance, look for frames that are as wide as the broadest part of the face. Triangle shape faces are narrow at the forehead and widen around the chin, to balance out the top and bottom of the face choose a frame that is wider in shape. An upside down triangle is wider at the top than the bottom, to deal with this choose a lighter frame or even a rimless frame as this will draw attention to the top of your face.


A square face has a strong jaw line as well as a broad forehead, while the width and the length are in proportion. To make the face seem longer, try narrow frames that have more width than depth. The diamond face shape are narrow at the jaw and eye line, while the cheek bones are wider, tough this is the rarest face shape, you can still find frames to suit.A frame that have detailed brow-line or even rimless and maybe even cat eye shaped will suit very well with this face shape. The oblong shape face is longer than it is wide, and has a long cheek line. To make the face appear shorter and more balanced a frame that top to bottom depth is best to add depth to the face.

Anyhow, choose the right color, design and style of cheap eye glasses according to your skin color and facial form, you will certainly find the ones suitable to you most.
