When shopping for shades some of us may have to settle for anything that our opticians can fit our prescriptions into. Meanwhile, some are lucky enough to shop over-the-counter for non-prescription sunglasses. No matter which circumstance a consumer falls into summer requires at least ultraviolet protection. Don’t pack them too far away when winter rolls around though, since snow blindness is a very real threat in sunny but cold weather!

As cosmetic as sunglass shopping at first tends to seem, there are some technical aspects that must be considered. The first is, of course, the level and type of UV protection but the color, materials and even shape of the lenses play a vital role. Additionally, the color of a person’s iris can definitely play into the shopping priorities. Persons with very pale eyes will need extremely dark sunglass lenses when visiting many countries that tend toward bright sunlight. When starring at a sunset over water even in otherwise cloudy locations there will also be a brief but essential need for shades.

Emphasis here is on buying the sunglasses before boarding that plane or cruise ship since most of the sunniest places on earth also have a shortage of shopping centers and pharmacies. There’s a lot of things that are vital to travel like passports and local currency not to mention the ever present English to whatever dictionary. Don’t forget the basics of surviving the climate though since a severe sunburn or damaged retinas will be just as painful as being detained at a border somewhere. This advice can apply to domestic destinations like that southwestern dude ranch too by the way.

A quick consideration of ultraviolet must be mentioned. This is not so much of a problem as it once was though since even very low end sunglasses purchased from dollar stores will generally provide UV protection. Say no, though, if finding a batch that doesn’t have this feature. Over a long period of time overexposure to UV contributes to the development of cataracts. There are two types of ultraviolet to consider: UVA rays and UVB rays when exposed to the sun. Of the two, UVB is the more potentially harmful to human eyes. Sunscreens need to protect from both.

On this topic it needs to be considered that even clear polycarbonate lenses protect against UV rays. That’s a very good argument in favor of wearing corrective lenses! Another aspect to consider is the amount of light leak that enters the eye area when lenses sit too far away from the face. This light is just as damaging as the light that enters the eye directly. This means that for those in very sunny areas sunglasses that are curved and have wide plastic frames will protect the eyes and surrounding tissue better. These also result in less eye strain which can result in facial muscle fatigue or headache. Squinting all day causes an overall feeling of discomfort. Those dark glasses that cover most of the eye area prevent this.

A person’s eyeglasses are usually his or her most important article of clothing and usually the one accessory that most people are self conscious of. Not only can the appearance of your eyeglasses effect other people’s perception of you, more significantly, they can affect you perception of yourself. A pair of ugly and clunky old frames can be embarrassing. On the other hand, the right pair of frames can be both sexy and stylish. Moreover, the right pair of eyeglasses can come to look so natural it can reach a point where a person appears unrecognizable without his or her usual specs.

With so much selection in the retail optical stores and, even more overwhelming, the ridiculous array of choices available on the internet, it can be a chore to find the set of eyeglasses that will perfectly compliment your features. You can’t very well try on every style in the store, or if you’re shopping online, you may not get to try them on at all. Some websites sport a “try-it-on” feature, where you upload a digital photograph of your face and then past the various frame styles over top to get an idea of the final look. But even this can be an arduous process. It’s good to have an idea about the conventions of eyewear fashion before you go randomly searching the racks or the web pages for your next set of glasses.

Most eyewear professionals will tell you there are seven basic types of face shapes. While we know everyone is unique, knowing which of the seven shapes is closest to your particular facial features is helpful to determine which frame style will best compliment your features. A round face is one with few angles or sharp curves. As the general rule with eyeglass frames is that they should contrast the face shape, a person with a round face will look best in narrow, angular frames. A person with a square face, on the other hand, will look best in round frames, while an oblong face would be complimented by frames that are thick from top to bottom so as to make the face seem shorter. If one’s face is like a base-up triangle, frames that are wider at the bottom will look best and vice-versa for a base down triangular face.

When it comes to color, the opposite is true: the color of the frame of a person’s eyeglasses ought to be congruent with the person’s coloring. A person’s coloring is determined by their skin tone, eye shade, and hair color. For the purpose of eyeglasses, people fall into two distinct coloration, either warm or cool. For skin tone, color is less important than undertone. Pink or bluish undertones are cool, whereas pale orange or yellow undertones are warm. Dark to medium brown, dirty blonde, black and salt-and-pepper hair are cool while light brown, red, blonde, and white hair are warm. Eye color is more difficult to categorize given the nearly infinite shades of the human iris, but generally speaking, dark blues, greens and browns are cool, while pale blues, greens and amber browns are warm. As we said earlier, frame colors ought to match a person’s overall coloration. Warm colored people should seek out light frame colors such as orange, beige, and bright reds or greens. Cool colored people look best in dark frames, such as deep blue, dark brown, or even black.

When choosing any pair of eyeglasses keep in mind that the frames should always be in scale with a person’s head size and overall body size. Big glasses look good on big people, while smaller people tend to stick to the rule that less is more.

The history of sunglasses can be traced back to ancient Rome around the year AD 60, where the Emperor Nero is said to have watched gladiator fights whilst holding up polished emerald-green gems to his eyes, thus reducing the effect of the sun’s glare. The very first actual recorded evidence of the use of sunglasses can be found from a painting by Tommaso da Modena in Italy, 1352, showing a person wearing sunglasses.

Earlier, around the twelfth century in China, sunglasses were worn by court judges, not to protect their eyes from the sun, but in order to conceal any expressions in their eyes as it was important to keep their thoughts and opinions secret until the end of each trial. These were flat panes of quartz that had been polished smooth and then smoked to give their tint.

It was not until 1430 that prescription glasses were first developed in Italy to correct vision, and these early rudimentary spectacles soon found their way to China, where they were again tinted by smoke to be used by the judges. The frames were carved out of either ivory or tortoiseshell, and some were quite ornate. During the 17th century prescription glasses were being used in England to help elderly presbyopic people to see better. The Spectacle Makers Company was founded in England who started manufacturing prescription glasses for the public, whose motto was “A Blessing to the Aged”.

The development of sunglasses, however, remained static until the work of James Ayscough, who was known for his work on microscopes in London around 1750. He experimented with blue and green tinted lenses, believing they could help with certain vision problems. These were not sunglasses, however, as he was not concerned with protecting the eyes from the sun’s rays.

Prescription spectacles continued to be developed over the next few decades, especially regarding the design of the spectacle frames and how to get them to sit comfortably on the nose. The frames were made from leather, bone, ivory, tortoiseshell and metal, and were simply propped or balanced on the nose. The early arms or sidepieces of the frames first appeared as strips of ribbon that looped around the backs of the ears. Rather than loops, the Chinese added ceramic weights to the ends of the ribbons which dangled down behind the tops of the ears. Solid sidepieces finally arrived in 1730, invented by Edward Scarlett. Later on, lens technology made a great leap forward when Benjamin Franklin famously invented the first bifocal lens in 1780, called the “Franklin split” bifocal, enabling presbyopic patients to read and also see in the distance without the need for separate distance and reading glasses.

Sunglasses, as we know them today, were first introduced by Sam Foster in America, 1929.These were the first sunglasses designed specifically to protect people’s eyes from the harmful sun’s rays. He founded the Foster Grant Company, and sold the first pair of Foster Grant sunglasses on the boardwalk by the beaches in Atlantic City, New Jersey. These were the first mass-produced sunglasses, and from this year onwards, sunglasses really began to take off. When I say “take off”, I mean that quite literally, because in the 1930’s, the Army Air Corps asked a company Bausch & Lomb (who still exist today) to produce a spectacle tint that would efficiently reduce high altitude sun glare for pilots. They developed a dark green tint that absorbed light in the yellow band of the visible spectrum.

In 1936, Edwin H Land patented the Polaroid filter for making polarized sunglasses. This type of tint reduces glare reflected from surfaces, such as water. Later in that same year, Ray Ban took the design of pilots sunglasses further by producing the aviator-style sunglasses that we know today, using this recently invented polarized lens technology. The edge of the frame characteristically drooped away at the edges by the cheeks in a sort of tear drop shape, to give a full all-round protection to the pilots eyes, who regularly had to glance down towards the aircraft’s instrument panel. The polarized lens reduced the glare from light reflected off the instrument panel. Pilots were given these sunglasses free of charge, but in 1937 the general public were allowed to purchase this aviator-style model that “banned” the sun’s rays as Ray Ban sunglasses.

In 1960, Foster Grant started a big advertising campaign to promote sunglasses, and pretty soon famous film stars and pop stars started wearing sunglasses as part of their image. The public began to adopt this new fashion of wearing sunglasses, not just to protect their eyes from bright light, but also as a way of looking good. Today, sunglasses are continuing to be improved with efficient UV blocking tints, cutting out all the harmful ultra-violet light. Various coloured tints are now available and, of course, the frame styles are very varied and exciting. Now you can really make a statement with your fashion sunglasses, transforming your image or creating a new look.  Designer sunglasses have certainly come a long way in just a few years, and now not only protect our eyes from the harmful sun’s rays, but are also an important fashion accessory – and it all started nearly 2,000 years ago with the Roman Emperor Nero!

It’s a well known fact that many people nowadays wear sunglasses purely as a fashion statement or a reason to look ‘cool’ and trendy, but modern sunglasses were invented with another purpose in mind and that was to serve as protection for the eyes against the rays of the sun. I have tried to put together an article detailing the medical or scientific ramifications, (not that I’m suggesting for one minute that sunglasses shouldn’t be worn as a fashion accessory), as to why people should wear sunglasses.

UV Protection
Despite the fact that the sun is more than 90 million miles away from our planet, its rays pose serious health and ocular dangers to us all. Exposure to Ultraviolet (UV) rays produced by natural sunlight has been associated with all sorts of eye conditions in human beings. Cataracts are a condition that involves the clouding of the lens of the eye. The lens becomes more opaque and is therefore less able to transmit light rays onto the retina. The image on the back of the eye is then blurred. The structure of the lens also changes as the lens becomes less transparent. Although most cataracts develop as people get older, studies have shown a link between overexposure to UV rays from sunlight and the condition. It has also been determined though, that people who wear sunglasses on a regular basis have a decreased incidence of this eye condition. Photokeratitis is another condition associated with the sun. Defined as the burning of the cornea (the clear front surface of the eye) by UVB rays, it is also known as snowblindness and typically occurs at high altitudes on highly reflective snow, thus people that ski would be more susceptible to getting the condition. Pterygium is a condition which can be defined as a raised, triangular or wedge-shaped growth of conjunctival tissue which grows over the surface of the cornea and can be caused by long-term exposure to sunlight, especially UV rays. Various eye cancers can also be attributed to excessive over exposure to UV rays in sunlight.

Sunglasses Reduce Glare
Obviously, when the sun is shining the brightness and glare interfere with comfortable vision and the ability to see clearly by causing squinting and eye watering. By reflecting the sun’s rays, many surfaces create glare- snow, water, windscreens, metal, the list is endless and all are items or conditions that most people will encounter almost daily in their lives. Polarised sunglasses are particularly effective when it comes to reducing glare.

Sunglasses Protect from Wind and Dust
Sunglasses worn in windy weather can act as an effective barrier against windblown particles from getting in your eyes and causing possible corneal abrasions.

They Keep Eyes Moist
Wearing sunglasses helps reduce the rate of evaporation of tears from the eyes keeping them moist and comfortable. Sunglasses can also help keep contact lenses from drying out due to this helping against evaporation.

Blue Light Protection
Long-term exposure to the blue and violet portion of the solar spectrum has been implicated as a risk factor for macular degeneration, especially for individuals that are said to be ’sun sensitive’.

Dark Adaptation
Just by spending a couple of hours in bright sunlight during the day can seriously affect the eyes ability to readjust to night time or indoor levels of light, thus driving at night, for example, can be more hazardous for people that spend time in direct sunlight than those that don’t.

Sunglasses Reduce Headaches and Eyestrain
It is our pupils that control the amount of light that reaches the retina at the back of the eye. The pupils’ size dilates and contracts depending on current light conditions. The darker the condition, the pupil dilates to allow more light in but the opposite happens in brighter conditions, where the pupil contracts to reduce the amount of light that enters the eye. In very bright conditions the pupil cannot contract enough to reduce the light entering the eye to a comfortable level, which causes squinting. Squinting has the effect of reducing the space between the eyelids which further reduces the amount of light entering the eye. Muscle fatigue associated with squinting and to a lesser extent, the constriction of the pupil, can lead to headaches and eyestrain. On bright sunny days, sunglasses, if worn, can reduce the amount of light that reaches the retina to a more optimal level for clearer, more comfortable vision.

Medication Induced Photosensitivity
Some types of medication, such as treatments for psoriasis, some birth controls and even tablets for skin treatment can cause people to suffer photosensitivity. This heightened sensitivity to sunlight can cause discomfort. Sunglasses can help to alleviate this problem.

Sunglasses Reduce the Effect of Jet Lag
Recent studies have discovered that sunglasses can reduce the effects of jet lag by fooling your body-clock. Apparently it seems that by altering your light patterns you can tweak your body-clock to adjust to new time zones more easily. Jet lag is actually a physical phenomenon, according to the study, not just something made up in peoples minds. The biological clock is actually a cluster of 20,000 nerve cells that are situated in the brain. Researchers discovered that people recovered much quicker from jet lag if they wore a pair of sunglasses during parts of their journey.

Recent fashion conscious eye gear lovers are going reverse the stream with increasing fondness for vintage sunglasses. It seems like retro fashion fever has caught today’s discerning and fashionable eye gear consumers too. Vintage eye wear fashion is the current buzzword and sunglass collections are reversing back to the 50’s, 60’s, 70’s etc., to don eyes of twenty first century.

Designs of those phase of eye gear were most outrageous and out of the box – and people are now dying to put on those timeless designs created by leading fashion designers of those eras. Hence, more you step back to the past in choosing a pair of glasses for you, more daring and dashing you will look today. So set your eyes for the vintage sunglasses to be at the vantage class amongst your peers. Any glasses that resemble with the retro are being seen from the vantage point these days. Therefore, little wonder why large, bold and attention grabbing lenses of vintage sunglasses are in vogue now instead of designs coming from latest canvas of designers.

Classic designs from 70’s, 80’s were marked by big glasses to cover up larger areas of eyes. Models and role models of fashion are bringing back those ‘larger’ fashion and creating rage amongst their aficionados. In stead of funky shades, round and traditional or square molds have become alive once again creating excessive flair and fever in the marketplace, across the globe.

Classic designs of vintage sunglasses rose from the past and have already setting blaze in the market, brushing up today’s fashion conscious eyes with bright colors, larger shapes, versatile ranges and styles that were once a rage in yesteryear’s celebrities. Today’s designers too are equally conscious about this reverse trend against time and reverting those designs by mixing with their own to quench the quest for their patrons’ demands for vintage sunglasses.

Oakley is one brand that has definitely been conceptualized and developed for athletes of world-class quality. These are the athletes that view the occurrences of limits as one of the many mere challenges that arise in life. The dedication of such athletes has certainly driven Oakley to go beyond conventional ideas when it comes to the development of standards. It is inherent in human beings to weed out problems and come up with more than satisfactory solutions to deal with such problems accordingly.

Another thing that makes Oakley the strong brand that it is pertains to state of the art production facilities and research supporting the authenticity of all of its inventions and products. CAD/CAM engineering is employed when the people of Oakley brainstorm their products into conceptualization and creation. Prototypes are then developed, which are then built in vaporized polymers of approximately 16-micron layers. These polymers are needed for they solidify once exposed to electromagnetic radiation. Spectropho-tometers are then utilized to test progressive builds. Environmental chambers and impact accelerators are also utilized to complete the testing process. Only then would be the newly created inventions be exposed to athletes all over the world for field testing. With such a process aiming for optimum quality, it is no wonder why Oakley has become one of the strongest brands to have ever hit the industry.
