Since the first glasses were invented, there was little change in this field. It was untill the 20^th cuntury that revolutionary changes were taken place in the glasses industry. So glasses produced before the time dividion are callled traditional glasses, those after it are called mordern glasses.Generally speaking, modern glasses are much advanced than those traditional ones, except in styles

Price should be one factor to be considered while comparing the two groups. Before the industrialization in glass field, eye wear are handmade only for those noble and rich people- eye wear in then time are luxury accessories. Later, as technology and techniques in the field matures on and on, the cost to make eye wear reduce all the more. For instance, some of nowadays modern eyeglasses can be purchased at several dollars.

Modern glasses are much lighter and durable than those traditional eye wear. Eye wear in the past are inconvenient to use, for they are mainly made with glass and metal, which are heavy in weight. Whats worse, glass is such a fragile material that may break into pieces easily under impact; metal will also deform easily in the mean time. On the contrary, such defects can never be found on modern eye wear. They are made from light weight and durable materials. For example, the lenses can be made from plastic, like CR39, a kind of very lightweight material; if the prescription becomes stronger on and on, high index lenses are also available- thick and heavy glass lenses are no longer needed. The frames can also be made from memory materials, like titanium, memory plastic, which can rebound to their original shapes after being twisted and bended.

More fashionable elements can be found on modern glasses than on traditional eye wear. When it comes to the 20th century, people begin to pay more attention to more than functionality that is what traditional glasses are mainly used for. And fashionable and personal elements are attached great importance since that period by both wearers and manufacturers. And now, many people tend to use eyeglasses as something of decoration, though many people are still in need of vision correction. One of such good example is the popularity of non prescription eyeglasses. These eye wear are specially designed for people who have no vision errors, but want to be as attractive and cool as those glasses wearers. To be simple, functionality is the main feature of traditional eye wear; fashionable and personal elements are now the main features on modern eye wear.

Mordern glasses have many advantages over traditional glasses. So people in the past refused to wear glasses. But today, people treat glasses as a fashionable accessory.

Nowadays, the polarized eyeglasses are divided into mainly two categories: one is coated with a protective substance and the other has a filter enclosed within it. Prescription polarized sunglasses were developed by Edwin Land in 1936 to block out solar glare. The former one is more common.

Sunglass lenses should also fight against UV rays. In general, there are three types of UV rays, namely UVA, UVB and UVC. These UV rays in different types have their respective risks. For instance, UVA can cause premature skin aging and UVB is a potential reason for skin cancer. UVC is more commonly found in artificial sources such as lamps.

The basic principle behind polarized lenses is that they can restrict light waves to a singular direction. Polarized lenses can now absorb solar glare from reflective surfaces by 99% or higher. Moreover, Oakley offers polarized lenses with moulded coating at the molecule level, which provides over 99% glare protection.

Polarized sunglasses are needed during most outdoor activities, such as skiing, snowboarding, fishing and so forth. These glasses are particularly helpful for fishermen, because sun reflection in their eyes can affect their eyesight into the water. Polarized sunglasses are needed not only in the summer but also in the winter.

One way to differentiate replicas from authentic polarized sunglasses is to rotate them. If the light passing through the lens changes intensity, the lens is forged. It is wise to choose quality polarized sunglasses, rather than cheap pairs.

It is the special coating on the outer surface of sunglass lenses that filters the UV rays, rather than lens color. Long-term exposure to UV rays can be quite harmful. Selecting sunglasses, the most important factor is UV protection amount. Those with 99% to 100% UV protection are competent. Price and darkness are secondary factors.

As the summer coming near, you’d better choose a pair of sunglass to protect your eyes from the harmful sunlight. Prescription polarized sunglasses are recommended for you.

You need bifocal reading glasses if you develop presbyopia. If you don't understand what the words mean it is simply a condition where the eyes not only has difficulty in focusing on distant objects but has trouble focusing on nearby objects as well.

There are four kinds of bifocal lenses to choose from. The choice is really yours on which of the designs are more comfortable for your eyes. All of these designs are functional and succeed in correcting the blurring of vision.

The lenses which has a round segment in the lower area of the lens

The semicircular segment which looks like a big letter D in the lower half of the lens

The rectangular section placed on the lower half of the lens, and

The distinct division of the lens into an upper half and a lower half.

These four types make the distinctive divisions of the lenses and are not aesthetically attractive to most people. It is good that these four types can be integrated into progressive reading glasses where the distinct lines disappear and only one solid lens can be seen.

These bifocal reading lenses could also be tinted to fit the frames of favourite sunglasses and become reading sunglasses. However, this can be more expensive than the regular ones.

The choice of the type of bifocal reading glasses is for you to decide on as no matter what the decision may be, the function will remain the same. Only thing is, progressives are more expensive and the expense can increase if you have them tinted for sunglasses purposes. But if it means that you can drive at ease and go to the beach in comfort, then the cost could be ignored.

You can get these bifocal reading glasses from your optician or optometrist, but do not think that if you go to a pharmacy and just pick up a readymade pair that it would function in the same way.

If you insist on getting the OTC type there may be risks like dizziness and nausea when you use them. That is caused by the measurements not fitting those of your eyes.

Remember that no two people are exactly alike and that is the same when it comes to reading glasses. Each eye has a distinction and careful measurements and calculations are needed to be made so that the bifocal reading glasses lenses are custom made to fit your eyes.

If you want to buy eyeglasses for women, you can go to this place to buy this kind of eyeglasses so that you can buy one suit women best. There are many types of eyeglasses and you may choose them according your own choice.

Women have always been fashionable. In fact, their style transcends gender. You can see them donning pants and jeans as if these clothing items have been made specifically for them. They could wear men's watches and ties with so much ease and without losing their femininity. They could also sport women's aviator sunglasses, just like the army Flyboys and hunks like Elvis Presley and James Dean did.

Large Lenses. An aviator will never be considered one unless it has large lenses. Fortunately, women love huge lenses because it definitely protects their eyes from the heat of the sun, as well as allow them to make their own bold statement. Most of the lenses can cover the entire eye socket. You can even find some of them that reach to the cheeks. For women, bigger ones will always mean the better bunch.

Thinner Metal Frames. Most aviators are made of metal frames, but those of women appear to be thinner. This could be because thicker ones tend to appear more masculine. To soften the look of the sunglasses and to broadcast femininity in its design, the metal frames are made to be slimmer than the others.

Polarized or Mirrored. Most of the glasses that are being sold today are either polarized or mirrored. These features also extend to women's aviator sunglasses. When you say polarized, the glasses can prevent the glare of the sun from reaching the eyes. On the other hand, mirrored sunglasses can reduce the amount of sunlight that blocks your view to as much as 60 percent, so you can have much clearer vision.

Arms with Rubber Tips. The arms of the glasses are also covered with rubber. This is to ensure that they do not suffer from any discomfort because of the tightness of the metal into their ears. Rubber arms can also come in different colors, which permit their sunglasses to look entirely sassy and charming. It would not be surprising to find women who buy aviators solely on the color of the rubber.

Design. Of course, women will always consider aesthetics on their purchase, and they would never be disappointed on the choices that they have. They can opt for the vintage aviators with their funky-colored metal frames, designer ones with accompanying semi-precious stones or crystals, and glasses designed exclusively for them by well-known fashion artists such as Dolce and Gabbana, Versace, Stella McCartney, and Chanel, to name a few.

Impact Resistance. The lenses in sunglasses today are also very strong. Even when you accidentally drop the glasses on hard surfaces, they do not easily crack, because of their thickness. They are also not easily scratched. Simply put, with aviators for women, the girls have a way of going practical with their fashion.

All in a simple word, to buy eyeglasses for women is really a time costing thing. However, women also have discerning tastes. They do not just settle for anything, even when it comes to their aviator sunglasses.

When we get old, our eyes begin to weaken, we may have some difficulty to focus on the close objects, at that time, a pair of reading glasses is needed for us to view smaller text and images. Some of us prefer to choose to wear the traditional reading glasses to help close reading, while others prefer to take the bifocal or progressive glasses because they will help them to see far distance and near distance at the same time without changing glasses.

Bifocal is a kind of glasses that were developed to offset a common vision problem among presbyopic wearers. Bifocal glasses have to be equipped with two focal points. Presbyopia was a common vision problem to those people who were going to fifties or becoming older. This visual problem caused a difficulty in seeing close up objects. People often call this eye problem:” too short arms”, this common phrase describe this symptom vividly. Why they called this? This is because presbyopic patients are used to hold the reading objects at an arm’s length, in which position can they see clearly. The need for bifocal eyeglasses is still driven by another visual problem, either nearsightedness or farsightedness. Some presbyopic patients have got farsightedness or myopia at an earlier age. Without the help of bifocal glasses, they have to use two separate pair of prescription glasses. That is really inconvenient if they have to make visual switches between different ranges.

Although a lot of wearers adore bifocal glasses and sing the praises of this kind lenses, in fact this entity is far from perfect. Those symptoms or side effects are closely linked with visual experience. So, it is the lens design that matters and leads to these bothersome or disappointing problems.

Franklin bifocal is the first bifocal eyeglasses design. He developed bifocal glasses in 1784. But now this lens has different designs. Franklin bifocal added reading segments in different shapes into a primary lens. Reading parts usually account for a small portion of the whole lens. But this kind of design could lead to a problem which just mentioned. Because there is a crossing line on the bifocal lens and it will cause frequent image jump. Headache and dizziness are actually subsequences of image jump that occurs from time to time. Bifocals with reading segments have a similar situation.

It usually takes a period to adapt to bifocal eyeglasses. Certain defects have been reported on those visual aid devices. Commonly heard ones include headaches, visual dizziness and image jump. What is the reason for these unwanted problems associated with bifocal eyeglasses? In most cases, factors of fashion will not cause problems that are associated with lens function.

In order to keep healthy, I like outdoor activities very much. But there is a problem: the sun light sometimes make the acctivities impossible, or we can not perform very well under strong sun light. For example, people playing golf may have the experience when their games are interrupted by sunshine, it is really disappointing when they can not even see the holes. In similar cases, transitions glasses be very useful. I like discount transition glasses.

Why don't I wear sunglasses? Well, I wear regular glasses, and I can't find sunglasses to fit over my regular glasses without making me look like my late grandmother when she went out for a Sunday drive. And, frankly, prescription sunglasses are far too expensive for the limited utility they would provide.

Recently, though, I was clued in to the flexibility and practicality of Transitions lenses. These are the prescription lenses that darken automatically in response to UV rays and lighten back up again when you go inside. So I decided to try them as a solution to my late-day golfing woes.

I've played several rounds now with my discount transition glasses and have been generally impressed.

When it comes to reading the greens, the darker lenses don't seem to hurt or help - basically, I can't tell any difference either way. And when the round is over, and it's time to hit the 19th hole, the lenses lighten up completely within a couple of minutes, which doesn't bother me personally at all. (Years spent in dimly lit dives have apparently inured me to temporary murkiness.)

They allow me to keep an eye on my ball in all but the most blinding conditions, which makes my late-day round far more enjoyable. Even when not facing the sun, I seem to be able to follow my ball against the blue sky much more accurately, cutting down considerably on time spent stomping through the rough.

The one downside to Transitions lenses comes on partly cloudy days, when stretches of bright sun are broken up by sudden walls of thick, fast-moving clouds. On one such day, I stood addressing my ball when gray clouds passed overhead. Suddenly, it was hard to see my ball. It felt like a Biblical plague of darkness, and I began looking around for locusts or frogs. Well, not quite. But I did have to step away from my ball and let my eyes get used to the shade (and allow the lenses to lighten up a bit).

Transition lenses are not only good for golf. They are for many different outdoor activities. I like discount transition glasses. Not expensive, but very practical. They give me a better outdoor life.
