Several brands that provide square sunglasses

June 17th, 2010 by Jay Furlong No comments »

Sunglasses are currently provided in many types according to functional and style classification approaches. Evaluating frame shape, there are square sunglasses, round sunglasses, rectangle sunglasses and so forth. What is the reason for the existence of those differently shaped sunglasses? One possible explanation is that the classification in terms of sunwear frame shape can diversify customers’ demands for sunglass styles. This is similar to the practice in prescription eyeglasses. Sunglasses are a necessary accessory for millions of people around the world. It is a disaster if all of them have the access to only one frame shape. Another explanation is probably the guideline that the frame shape should contrast with the wearer’s face shape. Human beings have different facial shapes like round, square, oval, oblong and triangles. These different face shapes require specific complementary frame shapes while using sunglasses or eyeglasses. It is for sure that not all people will get equally satisfied with a uniform frame shape.

As one of the most popular styles of sunglasses, square sunglasses are now available from many reputable brands. The remaining of this article gives some examples of popular styles from different names. Nike GDO square sun glasses are suitable for both men and women. Like other eyewear products from Nike, these square-shaped sunshades have the best blend of style and durability. Hallmarks of Nike also include quality materials and long-wearing comfort. Square sunwear from Nike use Nike Max Lens technology which ensures precise visual information at all angles of view. These sunglasses feature first-class UV absorbency, capable of blocking 100% UVA and UVB.

Tory Burch also provides square sunglasses within its oversized sunwear collection. This model released by Tory Burch is a combination of a vintage vibe and a modern twist. They are simple yet ultra glamorous with large modified square plastic frames. Like other eyewear products in the Tory family, these sunglasses have the Tory Burch signature logo embedded at the temple. Optional lens colors contain black, brown, olive and amber. Gucci is also providing squared sunwear. A typical model from this reputable brand takes use of vented lenses. They complement square, round, oval or heart-shaped faces.

Presbyopia glasses in different forms

June 16th, 2010 by David Wachler No comments »

Some people may not know the exact meaning of presbyopia glasses. In simple words, it refers to prescription eyeglasses for presbyopia correction. It is necessary to discuss some aspects of this bothersome eye condition. Presbyopia is a natural part of aging and individuals over 40 years old will suffer this problem sooner or later. Most eye doctors believe that presbyopia is a natural phenomenon and is independent from other vision problems like nearsightedness and farsightedness. The first and foremost sign of developing presbyopia is a difficulty seeing details up close. At this point, old eyes can not grasp clearly the notes and signs on materials that are just in front of the body. Over time, the old eyes will continue to advance and become more rigid.

Since a majority of the world’s population will suffer presbyopia, finding appropriate solutions become a great and significant task. Until now, major treatments for presbyopic patients include presbyopia glasses, contact lenses and surgeries. The first solution is the commonest because it is the safest and easiest. Eyeglasses for presbyopic correction come in different forms. Reading glasses have a longest history and they are followed by bifocal reading glasses, trifocal reading glasses and progressive reading glasses. This progress in presbyopia eyewear represents the continuous development in lens industry. In detail, reading glasses use single-vision lenses which can only compromise presbyopia and “restore” close vision. Bifocal reading glasses have two focal points and thus can deal with another refractive error. More powerfully, a trifocal lens is capable of managing intermediate vision. Progressive reading glasses are widely recognized as the most advanced form.

Except for various forms of presbyopia glasses, prescription contact lenses in bifocal, trifocal and progressive forms can also correct presbyopia. Contact lenses in different forms are actually made in similar concepts to corresponding eyeglass lenses. And they function also in similar ways. Unlike presbyopic eyewear and contacts, surgeries like LASIK, PRK and CK can help cure presbyopia in a relatively permanent way. During these surgeries, an ophthalmologist will use artificial multifocal lenses to replace the old, improper-functioning natural lenses.

Colored fashion sunglasses

June 16th, 2010 by Andrew Rabinowitz No comments »

There has been a dramatic change in the sunwear industry. The best testimony to this is that fashion sunglasses account for the majority of sunwear products in the modern market. All of us know that sunglasses were originally developed for eye protection against damaging ultraviolet (UV) rays contained in sunlight. Some scientific research have pointed out that excessive exposure to UV rays is closely linked with an eye disease called cataract. This condition usually causes a difficulty in seeing things clearly or we can say that it leads to vision blurriness. Eyewear that made of UV blocking lenses is called sunglasses which can help filter out unwanted, harmful UV rays and high-energy blue light. It is definitely true that sunglasses were initially aimed to help human beings fight against these harmful rays. Nevertheless, a modern pair of sunglasses means more than functional help.

A phenomenon in the current sunwear market is that nearly all buyers try to pursue fashion sunglasses, which usually come with the most stylish elements. In other words, it is a common thought that sunglasses should also be fashionable, in addition to helpful. And fashion statement of sunwear has two dimensions. One is to take use of unique and unusual frame styles. Large Aviator sunglasses are a perfect example. And there were popular cat eye sunglasses during the first decades of 20th century in the United States. But in fact, stylish sunglasses made of attractive styles actually are quite limited in diversity. It is hard to create lots of unique sunwear styles.

A wider dimension involves utilizing all possible colors to decorate both sunwear frames and lenses. Fashion sunglasses currently available come mainly in this group. Supposed to block out harmful rays, sunglass lenses should be colored. While dark is the widely used color traditionally, now it is technologically feasible to take use of any regular colors, such as green, blue, purple, gray, orange and red. Tinted or photochromic lenses in these colors will help fashion-conscious people gain an attractive look on face. Moreover, unusual colors have also been applied to sunwear frames and lenses, like burgundy, camouflage, chocolate and peachy.

A big trend created by Sarah Palin eyeglasses

June 16th, 2010 by Andrew Rabinowitz No comments »

Believe it or not, the trends in the eyeglass and sunglass worlds have been greatly influenced by a couple of well-known celebrities. Have you heard of the impact made by General Douglas MacArthur on Ray Ban Aviator sunglasses? Do you know that round eyeglasses have gained much popularity after Harry Potter’s first appearance with a pair of round eyewear? If you do not know all these widespread stories, a current one is for you. In the past two years, rimless eyeglasses with clear lenses have been one of the biggest trends among Rx eyewear users. And the celebrity who has contributed exclusively to this style is named Sarah Palin. The rimless eyeglasses worn by Sarah Palin during 2008 U.S. vice presidential debate are now widely called Sarah Palin eyeglasses. Created by Japanese designer Kazuo Kawasaki, this eyewear model has become a much-have fashion accessory for a great number of ladies around the world.

How popular are these eyeglasses currently? According to the vice president of Italee Optics, Inc, “we began hearing from our authorized dealers and they wanted to stock multiple pairs of the exact same frame and style and color that she had”. As the world’s largest online retailer of contact lenses and eyeglasses, Costal Contacts announced in January of this year that Sarah Palin eyeglasses in 8001 model have been the top selling design of rimless eyeglasses for the past year. Charging only $49.95, the Sarah Palin frame at Coastal Contacts has been the top of its best sellers list for over one year.

Even after her failure in the U.S. presidential election, the unique and attractive eyeglasses have helped her gain a special status in the area of eyewear. From a political perspective, there are some people who love her and some who hate her. But Sarah Palin eyeglasses have greatly boosted the popularity and acceptance of rimless eyeglasses among Rx eyewear users. A majority of users believe that it is a good choice to get a smart and sophisticated look.

Principle and functionality of polarized sunglasses

June 15th, 2010 by David Wachler No comments »

Sunglasses in colorful models are meaningful for people who are fashion conscious. Red sunglasses, pink sunglasses, yellow sunglasses and others are some of the popular styles. When more and more customers increasingly focus on sunwear appearance and style, it is worth emphasizing that the original functionality and other functional benefits should not be ignored. Buying any pair of sunglasses should first make sure 100% UV ray protection. Excellent protection against harmful light has long been and should continue to be the most valuable gift sunglasses can give. Yet regular sunglasses may not be competent in special conditions. For example, if there is strong glare reflected from flat surfaces on a sunny day, normal sunglasses can not shield the eyes adequately. In this case, polarized sunglasses are needed. Briefly speaking, polarized sunwear is aimed to reduce sunlight glare in outdoor circumstances, which is a great help for certain groups of people.

How can polarized sun glasses bring this functionality? Or what is the principle behind this helpful function? The sunlight is not polarized in its original form. However, flat surfaces like smooth water can separate sunlight into two polarized components which will then be reflected and transmitted in different amounts. In detail, more horizontal components will be reflected than vertical components. And an excessive amount of horizontally reflected light is the major source of glare experienced by people in such an environment. Polarized sunglasses take use of lenses that have polarized filters with the transmission axis oriented vertically, thus they can filter out unwanted horizontal light reflected by smooth surfaces. This principle explains why fishermen, bikers, golfers, joggers and skiers will receive little glare when they put on their polarized sunwear.

Polarized sunglasses are now provided by nearly all notable sunwear brands like Prada, Versace, Dior, Ray Ban and so forth. This technology has been a basic requirement or capability which can be taken to evaluate an eyewear brand. Sunglasses made of polarized lenses all come in shades from light gray to very dark, or photochromic. In other words, polarized sunglass lenses can not be crystal clear. This is a simple tip to check if your sunglasses are polarized.

Whom are rectangle eyeglasses for?

June 14th, 2010 by David Wachler No comments »

Since the number of people who need vision aid is so large, the diversity of needs is supposed to be correspondingly wide and large. It is the opticians’ responsibility to measure patients’ prescriptions and the responsibility of precise lens fitting relies on both opticians and lens manufacturers. During the long history of prescription eyeglasses, proper and precise lens fitting has been followed strictly according to patients’ prescriptions. Getting Rx lenses appropriately fitted based on individual visual needs has been considered as a task of the highest priority. After getting this task well finished, eyewear manufacturers and distributors have also paid much attention to customers’ varied needs in terms of frame shape, frame material, frame style, frame color, lens material and so forth. In this article, we will focus on frame shape and discuss in detail rectangle eyeglasses.

Everyone has a basic facial shape falling into seven major standards, namely, round, oval, oblong, base-down triangle, base-up triangle, diamond and square. Even if there are some variations, these seven facial shapes can cover the vast majority of people all over the world. Recognizing personal facial shape is the first step of determining whether rectangle eyeglasses are personally suitable. Any pair of prescription eyeglasses will stay on the wearer’s face if it is expected to function properly. So, the overall appearance of the eyewear is closely associated with the match-up between frame shape and facial shape. Eye care professionals have reached an agreement that the frame shape should contrast with the wearer’s face shape. Following this rule or suggestion can make your purchase a successful one.

Knowing the guideline stated above, it is still necessary to recommend rectangle eyeglasses exactly to certain groups of people. A rectangle eyeglass frame usually has sharp angles or strong lines. This feature is a good “tool” to offset the curved lines featured by a round face which has the width and length in the same proportions. A round face has almost no angles. According to the above rule, rectangle eyewear is most suitable for round faces. Another group of people who can benefit well from rectangle glasses is those who have an oval face.

Modern technologies used in retro vintage sunglasses

June 14th, 2010 by David Wachler No comments »

Sunglass designers living decades ago were creative enough that they had developed a couple of classic frame styles, which are provided by modern manufacturers as a special category called retro vintage sunglasses. Cat eye sunglasses, bug eye sunglasses and 80s oversized sunglasses are some of the examples of retro sunwear products that are regaining popularity among the average. For a majority of target customers, this is reminiscence. While most of them resort to these retro sunwear products for re-experiencing their classic style and appearance, there are actually additional benefits that are made available by modern manufacturers. During the past decades, lots of improvements and breakthroughs have been made and most of them are absolutely feasible to be used in retro sunwear styles. The combination of a retro frame style and an advanced lens technology brings greater benefits to modern customers.

The main purpose of this article is to list some of the latest lens technologies that have been applied to retro vintage sunglasses. Photochromic lenses may probably be the most advanced form of sunglass lenses until now. What is the effect of these lenses when they are fitted into a retro frame? Well, these lenses are auto-adjustable that they will lighten and darken in changing light conditions. These retro sunglasses will function well during outdoor activities lasting several hours because when weather conditions change or the sun begins to set, they can automatically adjust the amount of light that can enter the eyes. Another advanced lens technology that can be used in retro sunwear is polarization. Polarized sunglass lenses contain a special filter that can selectively filter out horizontal light reflected from smooth surfaces, reducing dramatically glare.

Moreover, retro vintage sunglasses can also utilize different types of lens coating. Anti-reflective (AR) coating applied to the back lens surface will help eliminate glare when the sunlight is behind. In other words, this coating prevents sunlight reflection from the back surface of sunglass lenses. Another helpful coating is called mirror coating. Applied to the front surface of the lenses of retro sunglasses, mirror coatings can block an additional 10 percent to 60 percent of visible light, enabling wearers to experience more comfortable vision.

Benefits of wearing orange eyeglasses

June 13th, 2010 by Randa Fritch No comments »

Regular prescription eyeglasses all take use of clear lenses, which means that these lenses are non-colored. Some people may have heard of orange eyeglasses, yellow eyeglasses, red spectacles etc. Since the lenses fitted in prescription eyewear frames are clear, the colors in these phrases refer actually to the frame color. Black is probably the most commonly seen color that is used in eyewear products. However, it is important to point out that the situation in recent years has changed profoundly. Prescription eyeglass frames come in any possible color as well as colorful combinations. All of us know that these new and modern eyewear products in various colors add more items to customers’ choice. But this is not the only benefit. There are some other benefits of wearing colored eyeglasses. Taking orange glasses as an example, this article tries to propose those possible benefits.

Frame is one of the most important parts of a pair of eyewear. After getting precise prescription fitting guaranteed, the key task of selecting eyeglasses is to choose a right frame, which should basically repeat personal features. The frame shape should be in opposite or contrast with personal facial shape. The frame size and the face size should be approximately in scale. Yet another critical element is frame color. Orange eyeglasses are generally suitable for individuals with a warm coloring, which is yellow-based. A warm-coloring person may have yellow skin tone, blue eyes and golden blond or flat black hair. For people with a warm color base, orange eyewear is a good option, because the two colors will complement each other quite well.

In addition to the appearance consideration, there is another benefit of wearing orange eyeglasses. Orange is definitely a comfortable color and making eyeglass frames in this color would help users gain comfortable vision. In fact, this benefit or advantage has yet been borrowed by sunglasses in orange tint. In the sunwear market, orange sunglasses are quite favorable among many shooters, hunters and the like. These devices can block haze and blue light and enhance the orange color of a target.

Powerful polarized bifocal sunglasses

June 13th, 2010 by Mark Burns No comments »

All of us know that regular sunglasses on the face can help in fighting against hazard rays or light in the sunlight. There are kid’s sunglasses and sunglasses for adults, both of which can get great benefit from the protection. Players in the current sunwear market can be classified according to different rules. Black sunglasses and sunshades in other colors are two major categories indicating a coloring difference. In terms of frame shape, there are full-frame, semi-rimless and rimless sunglasses. A special type called performance sunglasses is different from regular ones because they are used mainly in sports and are made with particular lenses and frames. Traditionally worn for eye protection, some modern sunglasses can also offer vision correction equal to that of regular prescription eyeglasses. This is not the end. The great progression in sunwear industry has made many more options or combinations a reality. Polarized bifocal sunglasses are a typical example.

Interpreting this easy phrase, a first additional function or benefit added to regular sunglasses is vision correction. The advantage claimed by bifocal reading glasses over traditional reading glasses may have been long recognized by the elderly group. Presbyopia is a major dangerous source to the eyesight of people who are in their 40s or older. Regular reading glasses can only help this group of people deal with presbyopia. If there is a presence of another vision problem like myopia or hyperopia, bifocal reading glasses are the more convenient solution. Nowadays, this kill-two-birds-with-one-stone function has been incorporated into sunglass lenses. Polarized bifocal sunglasses just take use of these lenses.

The other additional benefit provided by polarized bifocal sunglasses is associated with sunlight glare. In summer, the sunshine is always fierce and reflected glare from flat surfaces such as smooth water can be strong. This type of horizontally reflected light can be filtered by polarized sunglass lenses. As a result, these lenses can improve comfort and visibility during outdoor activities. Fishermen, boaters and drivers are some of the target users of these products.

Who need oval sunglasses?

June 13th, 2010 by Mark Burns No comments »

Supposed to provide eye protection against UV light outdoor and indoor, sunglasses produced by famous and emerging brands are available in traditionally dark color as well as modern fantastic colors like yellow, green, orange and the like. This diversification in frame and lens colors stands for modern sunwear users’ wide variety of appearance pursuit. Yet frame and lens coloring is not the sole approach to sunwear decoration. The frame shape is also a critical or even the most important element of an eyewear frame. Many people may have been quite familiar with the classic Aviator sunglasses. These sunwear models appear mainly in a combinational shape of round and square. There are also some similar sunwear shapes designed by other brands, which proves the extreme popularity of the Aviator style. However, this does not mean that all sunglasses are limited to this shape and this is the single option. There are still oval sunglasses, square sunglasses, oblong sunglasses etc.

It is theoretically feasible to make sunglasses in any wanted shape. People living on this planet can be grouped according to seven basic facial shapes, namely, round, oval, oblong, base-down triangle, base-up triangle, diamond and square. It has been widely recognized by eyewear professionals that it is important to realize a balance between facial features and frame features in terms of shape. Based on this criterion, it is acceptable to say that there should be related frame models in corresponding shapes as seven facial shapes. For instance, oval sunglasses should be available for people with an oblong or square face. In this way, the frame will successfully offset some obvious features, or exactly angles, of the face. This consideration is almost the same as that of regular prescription eyeglasses.

The mentioned seven or more sunwear shapes are just theoretically feasible. The current sunglass market has actually been predominated by only quite a few models in similar shapes, like rectangular and oval-square. Oval sunglasses are actually rarely seen. More common models come in oval variations.
