Product Information

Determining the size of the eyewear frame is the first step towards buying the right pair of sunglasses. When we say frame size, it actually refers to the fit of your shades and should not be confused with their coverage. To determine the right frame size look for the dimensions, which are often mentioned as the eye size, bridge size and temple size. Shop By Style: Aviator Sunglasses | Oval Sunglasses | Rectangular Sunglasses | Round Sunglasses | Wayfarer Sunglasses Although there’s no denying that you look great in your trendy pair of sunglasses but there’s another reason you wear them. Your shades might help you make a statement without saying a word, they also protect your eyes and the delicate skin around them from harmful ultraviolet rays that filter through on even the cloudiest of days. Even though the mighty Sun is millions of miles away from us, it still emits UV rays that play an important role in causing macular degeneration, cataracts and growths on the eye, including cancer. Hence, shield your eyes from harmful UV rays during outdoor activities like watersports, snowsports and driving in bright weather with a pair of good sunglasses like Ray Ban Sunglasses.

The photochromic lenses provide automatic sun-sensitive light adjustments for greater comfort outdoors. And the clip-on sunglasses can be conveniently stored in your vehicle for those bright, sunny days when you need darker lenses. UV and glare protection For the ultimate prescription eyewear suitable for all lighting conditions, some opticians recommend eyeglasses with photochromic lenses and a frame with integrated magnetic clip-on sunglasses. While radiative cooling materials are not new, many other radiative cooling strategies require the use of polymers to work. This new “cooling glass” is an interesting alternative to these other materials, the researchers say, as its harder nature should make it more robust to long-term weathering. It is described in the journal Science. The styling of prescription sunglass frames is nearly the same as withnon-prescription sunglasses . Prescription sunglasses are available in almost all of the same fashion, designer and celebrity eyewear styles. In use, the coating first reflects up to 99 per cent of solar radiation to stop buildings from absorbing heat. It then emits heat in the form of longwave infrared radiation into the cold universe, where the temperature is generally around -270oC.Wearing sunglasses that have UV protection can protect your eyes from the harmful effects of the suns rays. Moreover, sunglasses with polarized lenses can help to reduce the glare that causes eye strain when looking at bright surfaces on sunny days. Researchers at the University of Maryland have developed a new microporous glass coating that can cool indoor temperatures without using electricity. The new technology could lower a mid-rise apartment building’s annual carbon emissions by up to 10%. It's a game-changing technology that simplifies how we keep buildings cool and energy-efficient," said Assistant Research Scientist Xinpeng Zhao, the first author of the study. "This could change the way we live and help us take better care of our home and our planet."

The team used finely ground glass particles as a binder, allowing them to avoid polymers and enhance the long-term outdoor durability of the glass. They chose the particle size to maximize the emission of infrared heat while simultaneously reflecting sunlight. Not all sunglasses fit all faces. Everyone has a different face shape, such as a heart, square, oval, round, triangular, or diamond face. Identifying your face shape is crucial to finding the best sunglasses for men. Oval face Many optical shops and online eyewear retailers offer special discounts on prescription sunglasses. A well-suited pair of sunglasses can instantly uplift your appearance by making you look bright and attractive. With most brands offering their products online, choosing a pair of trendy latest sunglasses is easier. There are some classic style categories for both men and women; however, there is no hard and fast rule on what you can or cannot wear. Typically men opt for classic styles like aviators, square, rectangle, wrap-around, wayfarers, or sports eyewear. Among women, types like cat eyes, butterfly, bug-eye, and shield frames are more popular. However, most of these styles have been rendered g ender-neutral, providing more variety for you. Colours conventionally considered more masculine or feminine are no longer treated that way. Some really bold and outlandishly stylish sunglasses are available for your consideration. You can well buy colours like white, pink, or reflector unisex eyewear, as long as they suit your face cut. Once used only by army men, aviators are a rage among women too. Wine goblet, blue glass decorated with white and gold enamel, Iran, mid-19th century; in the Brooklyn Museum, New York. (more)The new technology, a microporous glass coating, can lower the temperature of the material beneath it by 3.5°C at noon. According to researchers, led by Liangbing Hu in the Department of Materials Science and Engineering, the coating has the potential to reduce a mid-rise apartment building’s yearly carbon emissions by 10%. The team report this ‘cooling glass’ in a paper in Science. Clubmaster sunglasses for men are extremely trendy for males and have an antique style that gives your clothes an edge. Clubmaster coolers for men look great on oval, square, rectangle, and diamond faces.

Late in the 17th century Bohemia became an important glass-producing area, and it remained important until early in the 20th century. By the 17th century England was making glass in the Venetian tradition that was notable for its simplicity. The glassmaker George Ravenscroft discovered about 1675 that the addition of lead oxide to Venetian-type glass produced a solid, heavier glass. Lead crystal, as it was known, thereafter became a favourite type of glass for fine tableware. Round faces feature bigger foreheads and jawlines but with softer angles. Elongating styles slim and sharpen a round face. Oversized rectangular and square sunglasses provide depth to the round face. Aviators suit this face shape too. Heart faceThis 'cooling glass' is more than a new material - it's a key part of the solution to climate change,” said Hu. “By cutting down on air conditioning use, we're taking big steps toward using less energy and reducing our carbon footprint. It shows how new technology can help us build a cooler, greener world." Mechanical engineering Professor Jelena Srebric and Professor Zongfu Yu from the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison are co-authors of this study. One of the newest mens sunglasses, Aviator shades offer sun protection and are great for oval, diamond, round, rectangle, square, and heart faces. In a phenomenon known as "radiative cooling," space effectively acts as a heat sink for the buildings; they take advantage of the new cooling glass design along with the so-called atmospheric transparency window -- a part of the electromagnetic spectrum that passes through the atmosphere without boosting its temperature -- to dump large amounts of heat into the infinite cold sky beyond. (The same phenomenon allows the earth to cool itself, particularly on clear nights, although with much less intense emissions than those from the new glass developed at UMD.)
