For many, Designer Sunglasses are one of life’s critical accessories. Whether your choosing a pair of sunglasses to make a big fashion statement, or you’re choosing them to help you play a sport better, you’ll always be able to find a stylish pair of designer sunglasses. Moreover, you’ll prefer a decent quality pair of designer sunglasses to the nasty, cheap lookalikes you get at the convenience store. Below, we give you best hints at choosing designer sunglasses that not only give you the look you want but also give you the protection as well.

Firstly, you should try on a number of designer sunglasses to find the best style for you but also ones that fit well. Many people make the mistake of buying sunglasses that they like the style of instead of ones that fit properly. Your new sunglasses should not pinch or cause any discomfort. Remember that you will actually want to wear your sunglasses on regular occasions, so comfort is paramount.

Choose a fair that fit you well - there’s nothing worse than having them flop around when you get a bit hot, then choose the ones that look great on you. This can be tricky as not every style you like will look good on your particular face. So, make sure to start with what you like for styles and try on as many pairs of designer sunglasses as need be, to find a pair that answers both to your style preference as well as what looks good on you.

Though many people buying designer sunglasses overlook this one in favor of how they look - it is absolutely crucial that you pick a pair that offer your eyes protection from harmful UV rays. Many designer sunglasses will offer this feature as it is so important for people to protect their eyes, but don’t just assume that because it’s a good name and a high price - that your sunglasses will, indeed, protect your eyes.

Lastly, when buying new designer sunglasses - you’ll typically see styles that offer polarized and non-polarized lenses. This depends on your personal preferences. Normally, polarized sunglasses are used by sports enthusiasts to help improve their vision and performance in strong sunlight.

In the cloudy winter months, it’s difficult to imagine the sun’s rays as anything but a welcomed change. But did you know the sun’s rays can also be harmful to your eyes? Ultraviolet light produced by sunlight is responsible for several vision problems, including snow-blindness, cataracts, and numerous degenerative eye conditions. The best way to protect yourself from these harmful effects is to always wear eye protection.

Ultraviolet light is light beyond the spectrum of light that is visible to the human eye, similar to x-rays or infrared light. It comes in three forms: UVA, UVB, and UVC. Earth's atmosphere filters out almost all UVC and much of the UVB light, meaning the majority of UV rays we encounter are UVA. Indeed, UVA is in part beneficial to human beings, as it is required source for vitamin-D production in the skin. However, overexposure to any or all UV rays can lead to advanced aging, skin cancer, or just good old sunburn.

When it comes to your eyes, however, UV rays are very damaging. Most eye care professionals recommend wearing sunglasses whenever you are going to see a prolonged exposure to UV rays. And, since UV rays penetrate our atmosphere even on the cloudiest days, having proper eye protection is always a must. It’s difficult to believe that light we can’t see can be damaging to our eyes, but UV rays, whether directly from the sun, or even by reflection, pose a significant risk to our vision.

The peak hours for UV ray penetration are between 10 AM and 3 PM, when the sun is at its apex. Other factors increase risk, as well. Due to their unique atmospheric qualities, higher altitudes and locations closer to the equator see higher UV levels. You should consider all these factors when you know you have to be out in the sun for an extended period.

But, since most of us don’t really have a choice regarding sun exposure – after all, most of us don’t live and work in caves – having proper eye protection is vital. When choosing sunglasses, make sure they guarantee UV protection up to 98% (or to 400nm). Glass is largely transparent to UV rays, so plastic or composite lenses tend to be a better choice. If your glasses have been coated in a UV filter material, they are even safer.

No matter what time of year, UV rays are always present. Although they tend to penetrate the atmosphere more during the warm summer months, they are also a risk during winter. Snow reflects UV rays, essentially letting them do twice the damage. Being aware of the risks of UV exposure is the first and most important step to protecting your eyes. But, with quality protective eyewear year-round, you can enjoy the warm, healthy sunshine carefree.

In a nutshell, light travels in the form of waves that basically vibrate in random directions and when this light is reflected off a shiny or transparent surface it is partly or fully polarised. The only exception being when the light is perpendicular to the surface, so when Edwin H. Land invented polarised lenses back in the 1930’s, he found that by using vertically polarised filters, he could block a lot of the glare producing light that was emitted horizontally to the surface.

Today, polarised lenses are made mainly from acrylic, polycarbonate or CR-39 synthetic plastics which include a polarisation filter enclosed in these lenses.

Polarised sunglasses have been designed to ‘absorb’ up to 97% of glare from flat, reflective surfaces such as snow, water and road surfaces. Our iris’ contract in bright light conditions helping to reduce the amount of light that enters our eyes but they are unable to block a certain amount of glare, so polarised sunglasses not only perform the function of fashion accessory but also of an important safety device used by the likes of drivers, sportsmen and yachtsmen. In fact, these kinds of people have been using polarised sunglasses for years but it has only become popular amongst the general public in recent years.

Polarised lenses used in sunglasses are great for reducing glare but they do have some disadvantages including difficulty in reading LCD screens such as ATM bank screens and some car dashboard monitors. It has been shown that images whose light reflects at certain angles are invisible to the eye as seen through polarised sunglasses. Also, certain topographical features may not be visible in snow, for example, which could make it quite dangerous. This is because the polarising filters in the sunglasses block some of the light rays reflecting from the surface.

On the flip side of the coin though, polarised sunglasses are great for people with long-sightedness disorders such as hypermetropia and presbyopia by helping the iris focus easier on nearer objects.

The main difference between a normal pair of sunglasses and the polarised versions are, whereas normal sunglasses decrease the actual intensity of all light entering the eye through the lenses, the polarised lenses although doing the same, would do so in a more selective manner.

Whether you’re looking for polarised sunglasses or just the normal variety, we stock an unbeatable range of authentic designer sunglasses for both adults and kids at our website The Black Rhino.

You are probably fairly familiar with the basic science behind sunglasses. They filter out harmful light rays and protect your eyes from intense light. However, the technology behind sunglasses and creating new designs may have a few more tricks up its sleeves. Even in 2007, sunglasses are reaching new heights of science and creativity.

If you are a corrective lens wearer, you will love this feature for sunglasses. No one likes having to change out glasses every time they move from indoors to outdoors. Additionally, you have to worry about losing your sunglasses while you wear your prescriptions, or vice versa.

Photo Chromic lenses are typical prescription strength glasses while you are inside. However, when you step outside into the light, they morph into sunglasses. The technology of the Photo Chromic lens is as sensitive to light as your eyes are. Unlike your eyes, however, these sunglasses will adjust in accordance with the magnitude of light to provide the necessary protection.

Sunglasses with lenses that transform automatically from clear to dark may not be particularly brand new information to everyone. They have been on the market for several years, and have now been revolutionized yet again. New sunglasses currently in development will change not only from clear to dark but also to shades of yellow, green and purple.

Not only will the transition occur much faster with these sunglasses, but they will offer many more options as well. They will be able to improve visual contrast, as well as brightening low-light conditions. Unlike traditional color changing lenses, these sunglasses will be controllable by the wearer. A small dial on the arm can take you through a spectrum of shades and tints.

The lens material will be made from a plastic can change its color and transparency when the sunglasses receive an electrical charge. The lens contains a gel-like solution in between the layers that helps transport charged particles. A watch battery delivers the charge. When the electricity is transmitted, the molecules change from transparent to a variety of shades and tints in seconds or less and your glasses become your sunglasses!

Visual effects are not the only advances made for sunglasses in recent years. Many product developers are beginning to see the need to further integrate technology and communication into everyday life. For this reason, you can now purchase sunglasses that are also your mobile phone. Since the advent of the headset, it is a common need for one that does not get in the way of your sunglasses. This new phone turned eyewear is an obvious solution to the problem.

Another extremely popular tech toy today is the MP3 player. Long gone are the days of the Walkman or even the Discman. The computer age has taken over all facets of our existence, including the music we listen to. Few individuals today are without an MP3 player. Heaven forbid we are caught anywhere without ever song we own to keep us company!

Following the desperate need we have to be surrounded by our music, sunglasses have been developed to accommodate us. Sunglasses with built-in speakers can be plugged into your MP3 player in the same way your ear buds could. If this is not hi-tech enough for you, pick up a pair of sunglasses that actually ARE the MP3 player. Simply download your tunes onto your sunglasses and take off down the road.

Science is constantly changing and developing exciting new inventions. Twenty years ago you never would have believed someone if they told you that you may be listening to music on your sunglasses. New developments are happening all the time, so don’t be left behind. Pay attention to see what they come up with next.

The heat of the summer is out and yet you might see more people wearing those extra large shades that almost cover half of their faces. Well don’t ever think that they’re going crazy, instead (to give you a little info) they’re on a fashion craze. The wearing of aviator shades is now the latest trend when it comes to fashion. Maybe you’re the only one left behind. Like the incorporation of the camo gears in the latest fashion statements, this military equipment is also hitting the trend.

The aviator shades as the name implies were originally used in aviation by aviators and air force personnel. The military and other forces also used the same as protective eyewear especially when they are deployed in desert or tropical areas. The aviator shades are designed to keep the strong wind current and dusts or sands away from the eyes of the aviators especially when flying low on open planes. These glasses are smoked or dark colored to protect the eyes from the light of the sun. The aviator and military sunglasses were originally available as supplies for military along with the other tactical gears.

After spending years in the battlefield the aviator shades and military sunglasses have infiltrated the fashion boutiques. Several new designs of these glasses are coming out in different colors and designs. Fashion boutiques offer different kinds of military inspired fashion shades and glasses aside from their complete line of camo gears. If you are looking for the original issue aviator and military sunglasses you can check them out at the military supplies and surplus shops nearest you area. You can also order them online on the online military supply stores that offer a wide selection of brand new and surplus official issues of aviator shades and military gears and supplies.

If you have one you can flaunt it out as what others do especially when the sun is at its fullest or even when the sun starts to hide. The use of aviator shades and military sunglasses as fashion shades doesn’t choose any time or weather condition, you can use it as long as you can see what lies ahead of you. Or others just use it as headbands to adorn their heads and hairs.

You may be the type of person who never leaves the house without your sunglasses during the warmer months. Not only are they great protection from the sun’s glaring rays, but they’re also quite the accessory these days as well. And if you’re like a lot of people, you probably own more than one pair and scout the sunglass display in the local markets every time you walk by. Well, good for you for taking care of your eyes! But did you know that sunglasses are just important in the winter as they are during the rest of the year? It’s true, and here’s why.

Sunglasses actually play a big role in good eye health. The UV rays from the sun are very strong - all year round - even though they don’t always feel that way on our faces and bodies, especially fingers and toes during the chilling winter months. But nevertheless, they are and we need to protect ourselves - eyes included - from their harmful affects.

It’s actually very serious business, more serious than most people realize. Over time, UV rays can in fact, lead to diseases of the eye like cataracts (opaquacity in the membrane covering the pupil causing a decrease in vision), macular degeneration (discoloration of the cornea), or even cancer, that may require surgery or worse yet, be irreversible. And if your eyes are normally sensitive to bright light and the sun’s rays anyway, you may be headed for even more trouble if you don’t wear sunglasses.

You know how bright the sun can be when it reflects off the snow and hits your eyes - it hurts, right? Add in the ultraviolet element and there you have it. But by simply putting on a pair of sunglasses, you can not only avoid the discomfort of the sun’s bright and harmful UV rays reflected on your eyes, but you’ll also be preventing the possible onset of eye distress such as disease as well. So you see, sunglasses work double-duty (or even triple-duty if they compliment your appearance - wink, wink).

And don’t forget the kids. Even though children look adorable and make us smile when they put on a pair of cute, child-sized sunglasses, their eyes actually need protection the same as everyone else’s. So don’t hesitate to pick them up a pair the next time you’re passing by the kiddie styles and you hear those three little words - “I want that!” because you’ll actually be doing a good thing in consideration of their eye health.

Ray-Ban was founded in 1937 by Bausch & Lomb after lieutenant John MacCready asked them to make a pair of sunglasses that would not only protect his eyes from the damaging effects of the sun but also look good. Today, they are the world’s best selling sunglasses.

Pilots in the United States Air Force began to wear the sunglasses and when General Douglas strode on to a beach in the Philippines in World War II wearing Ray-Ban, the sunglasses became a massive hit back home in the USA. Since then, Ray-Ban Sunglasses have been worn in hundreds of Hollywood films and remains a favorite among celebrities.

Ray-Ban is a leading brand of high quality eye-wear and combines great styling with quality and comfort. A clean cut design and high quality materials ensure that Ray-Ban sunglasses are the most popular sunglasses on the planet.

Rayban Style

The two most famous sunglasses style in the world are the Aviator and Wayfarer. They also happen to Ray-Ban.

The name of the Aviator sunglasses arose because of the oblique teardrop shape of the lens. Naval aviators found that the oversized sunglasses would help to hide the white skin under their eyes caused by wearing goggles during flying. The bar across the nose also held a cigarette in place.

The glasses are designed to cover the entire eye and to stop sunlight from reaching the eye from between the glasses and the face.

The first sunglasses design to use plastic, the Wayfarer was a radical new look. They were invested in 1952 by Raymond Stegeman for Baush and Lomb.

Originally marketed to pilots, they were quickly found to be popular among female Hollywood stars, such as Kim Novak and Marilyn Munroe. Audrey Hepburn wore a pair of Wayfarers in the movie, “Breakfast at Tiffany’s”.

People are able to buy designer sunglasses at great prices from the Look Good Sunglasses internet shop. Look great when you buy chanel sunglasses or other designer sunglasses today.
