Great eyeglasses with much saving and valuable functions

July 25th, 2010 by Ray Didia No comments »

Eyeglasses that are made with specific prescriptions have been the most popular solution to vision problems for many years. And this status tends to continue in the near future. The large figure of eyewear users has greatly boosted this market. While shopping around for a pair of prescription eyeglasses, the labeled price and the function or functions provided will be the mostly considered factors. A pair of great eyeglasses should offer powerful functions and enable a customer to get much saving. However, there is likely a dilemma between these aspects. In detail, eyeglasses with more functions will usually charge a customer more money. For example, a pair of progressive reading glasses is usually much more expensive than another pair of regular readers. This rule can be proven in sunwear and safety wear industries.

The availability of eyewear products over the Internet has greatly changed the above conclusion. Those powerful eyeglasses, sunglasses and safety glasses that charge unreasonably high prices are usually offered by local optical stores. The situation over the Internet is that there are currently many large retailers providing magic glasses at much lower prices. It is easy to get great eyeglasses with much saving and valuable functions. Taking progressive glasses as an example, online customers only need to spend $20 or $30 on a single pair. At a local store, such a typical pair would probably charge over one hundred dollars. Today, great savings provided by online optical shops have been a major factor that helps them attract more and more customers.

The other factor contributing to the competiveness of great eyeglasses supplied by online retailers is their guarantee of eyewear quality. Progressive reading glasses are unusually powerful because they can offer vision correction at all distances. Tinted eyeglasses or prescription sunglasses are magic due to their ability of dealing with UV danger and refractive errors. Rx safety eyeglasses are exciting for they enable certain workers with poor vision to protect their eyes from suffering an injury. Offering great savings is not the sole responsibility taken by reputable online eyewear stores. They also ensure eyewear functionality.

Beneficial lens treatments used in sunglasses for men

July 25th, 2010 by Ray Didia No comments »

Compared with female wearers, male sunglass users usually pay more attention to the functional side of a sunwear. Those colorful and even strange elements incorporated in women’s sunglasses are mostly unattractive for most men. UV protection is always the first consideration made by male customers. But there are actually some other functional aspects that should be evaluated. Regular sunglasses only offer proper UV protection, but they do not incorporate some other treatments. Sunglasses for men can practically take use of certain extra treatments, which offer significant help.

The most commonly used treatment is polarization and the exact product is polarization sunglass lenses. In detail, men’s sunglasses which contain a special filter can selectively filter out glare reflected from horizontal smooth surfaces. Glare is very bothersome when staying in fierce sunlight. The filtration treatment embedded in lenses can eliminate “hot spots” of glare. Sunglasses for men also widely utilize anti-reflective coating. Many people know that scratch-resistant coating and anti-fog coating are sometimes used in eyeglass lenses. Now, anti-reflective coating is popularly applied to sunglasses. What is the exact help brought by this coating? Applied to the back surface of the lenses, anti-reflective coating help the wearer stay away from sunlight glare when the sun is behind. Preventing sunlight reflection from the back side is also important.

Another great treatment or technology is quite significant for sunglasses for men. This is the most advanced form of sunwear which brings a maximum degree of functional help. The exact name is photochromic sunglasses, which have lenses that are capable of changing darkness according to light conditions. It is common for some people to switch from an outdoor environment to an indoor circumstance. Without the availability of photochromic glasses, it is necessary to make switches between a pair of clear glasses and another pair of regular sunglasses. The innovative lens treatment brings significant benefit to people with poor eyesight. All of the above lens treatments are commonly used in men’s sunglasses.

What are discontinued eyeglasses?

July 24th, 2010 by Richard Schneider No comments »

It is a basic fact that many eyewear manufacturers have been around for many years or even decades. Eyewear brands like Ray Ban, Prada and Versace can all be dated back to several decades ago. And it is for sure that they have released many models of eyeglasses in their history. It is also widely recognized that the eyewear market is always changing in terms of frame style and even lens and frame technologies. Any eyewear brand who wants to attract and maintain loyal customers should try hard to make continuous innovations in frame design. Several models will be released in this year and some others in the next year. In this process, one facet is that new eyewear models will be developed every new year. This is commonly known by the public. But fewer people will know or pay attention to the other aspect that there are also many eyeglass models being discarded or discontinued each year. These discontinued eyeglasses have been always in the market for a couple of years.

It is hard to know exactly why these glasses are discontinued. A possibility is that these discontinued models are no longer fashionable after several years’ prevalence. It is hard for most eyewear styles to stay in the mainstream for many years, except for those with a classic design. Cat-eye glasses, bug-eye glasses, Ray Ban Aviator sunglasses and Wayfarer glasses are some other the never-out eyewear styles. Ok, there are absolutely some lasting styles but this is not the case for the majority of eyeglass models. From a historical perspective, discontinued eyeglasses account for a major proportion of the eyewear market, knowing that this market has such a long history.

It is necessary to know that discontinued eyeglasses are not exactly equal to unavailable eyeglasses. For instance, a manufacture stopped producing several models three years ago but these are still available in a small fraction of the local or online optical retailers. It is not surprising that there are some people searching hard around the Internet world for a certain model of discontinued glasses. In fact, it is a common thought among certain customers that they want to buy another same pair which has functioned well during the past years and only charged little money.

White sunglasses have been popular for many years

July 24th, 2010 by Richard Schneider No comments »

When summer weather begins to heat up, summer attire and other accessories will follow. Sunglasses have been a major accessory which helps block harmful rays contained in sunlight. In addition to this functional help, sunshades mean a lot in terms of fashion enjoyment and appearance enhancement. Nowadays, sunwear manufacturers try to find any possible ways to design new sunglasses in innovative styles, colors and even shapes. In retrospect to the history of sunglasses, there have been some classic designs using different elements. White sunglasses are a historic style and now are sold by lots retailers as a form of retro sunglasses. Most of us may have heard of sunglasses in other colors, like orange, yellow, purple, rose, green, and so forth. Neglecting their differences, these products have greatly supported the diverse demands from customers.

But we should be clear that sunglasses in different colors have dramatic differences. In most cases, the colors refer to sunglass lenses. They are exactly called sunglass lens tints. Until now, possible lens tints include green, yellow, orange, amber, rose, brown, and gray. These tints applied to sunglass lenses can offer additional advantages in specific lighting conditions. However, some other colors can not be applied to sunwear lenses. This can be exemplified by white sunglasses. This prevailing style does not refer to sunglasses that have white lenses, but white frames. This color is not transparent and lenses in this color will not allow light to pass through. Making this point clear is really important. Sunglasses with a white frame can create a unique look for lots of people. It is completely feasible to paint the whole frame white and an alternate is to add another color, creating a two-tone effect.

White sunglasses have stayed in the top fashion world for many years. And lots of celebrities have used these sunshades. As early as in 1967, Audrey Hepburn used a pair of white sunshades in a huge size, which seem completely like the wrap-around sunglasses of recent years. The movie titled “Two for the Road” has witnessed her image with white sunwear. Another example is that Princess Diana was photographed with white sunshades in 1989. During the past decades, white sunwear has remained as one of the most popular design.

Wine glasses as a unique product

July 22nd, 2010 by Jay Furlong No comments »

The time when all eyeglasses were black has forever gone. People who have a vision problem now have numerous options provided by eyewear makers. Compared with contact lenses and eye surgeries, Rx spectacles are widely considered as the most acceptable treatment or remedy. However, people living decades ago had probably been bothered by the plain, standard design of prescription eyeglasses. Rx eyewear users at that time had very limited options and the majority of their concerns were getting vision correction met. Nevertheless, modern folks have definitely realized a drastic change in the eyewear market, especially in the recent decades. Eyeglasses provided by modern manufacturers come in different shapes, use different frame colors, apply various temple designs and thus support a wide variety of demands. In particular, colored eyeglass frames have helped expanded Rx eyewear market greatly. A typical, new design is wine glasses.

Note that we are discussing eyeglasses. The phrase wine glass is commonly referred to a type of glass stemware that is used to drink and taste wine. In this case, wine means an alcoholic drink made from the juice of grapes that has been left to ferment. This is exactly the common explanation of this phrase. However, few people know that the word “wine” can also be a color. This is a dark red color. In some cases, it is also called wine red, indicating the color of the drink stated above. Knowing this difference, it is understandable that wine glasses refer to prescription eyeglasses that have a wine-colored frame in this writing.

In the remaining part, we try to point out what is the uniqueness of eyeglasses in wine color. Many wearers may have been used to green glasses, red glasses, yellow glasses or some others. These colors have been utilized in eyewear design for many years. But wine as a unique color is applied just in recent years. For certain people, getting a pair of eyeglasses that appears in the same color as wine is probably an exciting experience. It is foreseeable that wine glasses will gain further popularity.

Yellow sunglasses in different forms

July 22nd, 2010 by Jay Furlong No comments »

The summer weather makes the use of sunglasses a necessity for lots of people around the world. It is interesting but reasonable to group all sunglass users on this planet into two groups: those function-oriented and the others fashion-oriented. For the first group of wearers, it is fortunate that current lens technologies have make it easy for sunwear manufacturers to incorporate 100% UV protection in their products. For the second group, things sound a little difficult. This saying is based on the fact that the demands in fashion world are always endless. Nevertheless, it is undeniable that the current sunwear market can satisfy most of the customers in terms of fashion enjoyment. Yellow sunglasses are one of the fashionable products in recent years. This color can be commonly seen in many products in other industries. And its application in the eyewear industry is quite innovative.

Both sunglass frames and sunglass lenses can be tinted. And yellow sunwear as a wide concept can be referred to different types of products. Painting the frame into yellow brings yellow frame sunglasses, and tinting the lenses into yellow gets the design of yellow lens sunglasses. Both of these two major forms can be named yellow sunglasses, for their similar effects. Yellow-framed sunglasses usually take use of lenses in other colors, such as brown and gray. The appearance brought by yellow frame sunwear is quite attractive. And even Bill Clinton can not resist them. The frame can be cat-eye, but-eye or oversized.

The color yellow applied to sunglass frames means only fashion enhancement. But it has an additional functional benefit when applied to sunglass lenses. As the other type of yellow sunglasses, yellow lens sunshades have been widely recommended by the media and eye doctors. The degree of UV protection offered by sunglasses is determined mainly by the lens material used. The lens darkness or color is not the decisive factor of UV protection. However, different lens tints have been traditionally used in sunglasses, with an expectation to achieve additional advantages. In particular, sports sunglasses with yellow lenses can heighten contrast in overcast, hazy, low-light conditions during outdoor or indoor sports. What’s more, they can offer sharper focus by filtering blue light.

Three major categories of optics glasses

July 21st, 2010 by Reza Hyver No comments »

Optic as an adjective word means “connected with the eye or the sense of eyesight”. With this detail, it is easy to understand optics glasses, which refer to eyewear devices that are worn over the eyes with an expectation to get vision correction or eye protection. The key part that offers one or several functions is the lenses. They are exactly called optical lenses which have perfect or approximate axial symmetry that transmits and refracts light. And until now, optical lenses are typically made of glass or transparent plastic. In some cases, a set of simple lenses with a common axis are combined to form a compound lens. And a single lens has just a single optical element. During the long history of eyewear, these lenses have played a significant role. And different lenses and additional elements added to them have helped manufacturers develop numerous eyewear products.

Currently, there are exhibited in the eyewear market mainly three categories of optics glasses: prescription eyeglasses, rx sunglasses and protective goggles. This classification is according to their fundamental functional differences and neglects some combinational products. They are given the same wider concept simply because all of them use optical lenses. The first category is well-known and commonly used. Regardless of special eye conditions or cosmetic factors, there are mainly four vision conditions that require the use of regular prescription eyeglasses, namely, myopia, hyperopia, astigmatism and presbyopia. A common place among these four types of Rx eyewear is that their lenses have specific power or powers.

Compared with prescription eyewear, sunglasses and protective goggles are generally subsidiary optics glasses. The help offered by these two forms is commonly considered less critical. This can be simply proven by the figure of sunwear users and that of Rx eyeglass users. The use of prescription spectacles is a necessity for people who have poor eyesight. But most people wear sunglasses and protective goggles just for additional eye protection. Even if this is a fact, most eye care practitioners emphasize the use of sunwear and safety eyewear as frequently as they can.

Improvements made by modernistic glasses

July 21st, 2010 by Reza Hyver No comments »

According to historical record, the first use of magnification was in the 5th century BC by ancient Egyptian hieroglyphs. And corrective lenses were firstly used in the 9th century. Whether these records are true or not, it is undeniable that eyeglasses used for vision correction have been around for quite a few decades. In the long history of glasses, there have happened significant changes or improvements. Modernistic glasses differ greatly from those old ones in nearly all aspects. The biggest and most noticeable difference is the eyeglasses availability. Dating back to even one hundred years ago, it was uneasy to get a pair of prescription glasses. Only the elite had access to Rx eyeglasses, because of the scarcity. And at those early days, both lens and frame technologies were quite less advanced than today.

Optical lenses used in prescription glasses are the essential part which provides visual correction. After several centuries’ development or advancement, modernistic glasses are now greatly contributed by advanced lens technologies. A simple example is that superior lens materials like high index plastics allow strong lenses to be regularly thin. This was impossible in old glasses. And this improvement is quite meaningful because there is a large group of people who suffer from severe vision conditions. Another improvement in the Rx lens industry is the invention of multifocal lenses. Single-vision lenses as the traditional and regular form are not competent in some circumstances. Patients who have both presbyopia and myopia or hyperopia will discover that multifocal glasses like bifocals and trifocals much more helpful.

Lens improvements made by modern eyeglasses are certainly not limited to the two points mentioned before. Now it is still necessary to discuss some changes in frame style that can be seen in modernistic glasses. The most noticeable facet is frame color. Modern eyeglasses are now available in any possible colors, while traditional glasses appeared only in black or gray. In recent years, yellow frames, orange frames and some other models are quite fashionable among especially young ladies. This is unimaginable by our grandmothers and earlier generations.

Primary features of transition glasses

July 20th, 2010 by George Manche No comments »

For people without much experience of wearing eyeglasses, it is hard to understand transition glasses from the meaning of these words. Transition means the process or a period of changing from one state or condition to another. How can this term be used in eyewear products? In fact, these are an advanced form of eyeglasses that really involve different transitions. The exact part that brings such transition is the lenses, which can change their darkness according to the surrounding environment. It is widely known that sunglass products currently available in the market come in different darkness in their lenses. In a typical case, a light pair does not give enough protection in bright sunshine. And an opposite case is that a dark pair blocks excessive light and brings an uncomfortable feeling, especially while driving. For lots of sunwear users, this is a dilemma which is hard to conquer. However, the development of transition eyeglasses provides a perfect workaround.

In simplest words, transition glasses use lenses that are self-adjustable in terms of darkness. They can change from dark to light and clear according to different light conditions. These glasses will not cause users to squint in sunlight or fumble in poor light. In detail, these glasses are clear indoors and darken automatically in response to sunlight outdoors. When staying indoors, they function as regular prescription eyeglasses because the lenses are fitted according to the wearers’ specific prescriptions. Moving to an outdoor environment, they serve as sunglasses, or exactly prescription sunglasses. It is equally feasible to get 100% protection against the sun’s harmful UV rays.

This adjustable attribute of transitions eyeglasses is very helpful, because it brings unparalleled convenience. It is very convenient to use a transition pair in both indoor and outdoor conditions. In fact, transition glasses are just products from Transitions Optical Inc. A wider concept of these glasses is photochromic eyeglasses. Currently, most popular brands use the photochromic lens technology that is owned by Transitions Optical Inc., which has led most eye care practitioners and customers to refer photochromic glasses to transitions glasses. Actually there are some other brands which use their own photochromic lens technologies.

Profession glasses for extra eye protection

July 20th, 2010 by George Manche No comments »

Many people may find that their regular eyeglasses are suitable for all routine activities in daily life. But they can not function well during certain tasks linked with their special professions and personal hobbies. When it comes to the latter consideration, sports glasses are the right choice and these people may need to get an additional pair of sports glasses if they want to get free enjoyment. In fact, sports eyewear has been a big market for many years because these products are very helpful in protecting athletes and amateurs’ eyes during games. For their particular function of eye protection, sports glasses are considered as a sub-set of safety glasses. There are some other specialty glasses used by people with certain professions. They are exactly called professional glasses.

Professional eyeglasses cover a wide range of products that offer extra eye protection in some fields involving dangerous factors. To some extent, sports eyewear can also be grouped into this category, based on the fact that these glasses help greatly professional athletes shield their eyes. Of course, professional glasses have much wider applications. They can be used during shooting, hunting and so forth. Carpenters, plumbers, pipe fitters, machinists, millwrights and laborers are target users of professional eyewear. These jobs always involve risky sources that may seriously hurt the workers’ eyes. Some tasks require the use of side shields, goggles and full face protection. People who work in such an environment must wear a pair of protective glasses.

The most significant difference between professional glasses and regular glasses is the enhanced impact resistance. Eyeglasses for professional usage must conform to a higher standard of impact and shatter resistance. Moreover, both the frame and the lenses should be made according to this standard because they may be hit or attacked randomly. All eyewear products used in risky professions should meet specific criteria. Regular eyeglasses even with a high durability do not qualify as profession eyewear. In general, there are several frame tests for protective eyeglasses. They include high mass impact test, durability test and high velocity impact test. And these tests can group professional spectacles into basic impact and high impact types.
