Choosing Cool Designer Prescription Glasses and Sunglasses

There is something about a pair of sunglasses that makes them arguably one of the most essential ‘must-have’ items of all time. Not only are they immensely practical, offering protection from the dangers of the sun, they are an enormously versatile fashion accessory, available in a huge range of styles, colours and prices to suit every pocket. Given their worldwide popularity, sunglass manufacturing has become a very lucrative, and highly competitive industry and while some manufacturers rise and wane in the public affections, there is one company that remains forever synonymous with the eyeglasses that protect our eyes from the rays of the sun: Ray-Ban

Although the Us President, Benjamin Franklin, is often credited with inventing eyeglasses (he was the one who developed the first bifocal lens in the 1780’s), the first reading glasses were developed in Italy, as early as 1260. People continued to be fascinated by all things optical throughout the centuries that followed, then, in the mid-eighteen hundreds British scientist James Ayscough began to research tinted glass, and the possibility that such technology may be used to improve vision impaired eyesight. As successful as he was, it was not until 1929 that the idea that glasses could filter the sun’s rays was given any serious consideration. At that time, U.S. optical company, Foster Grant, began to develop the idea further, until finally, later that same year, the first ever pair of sunglasses were sold from a Woolworth’s store on the Atlantic City boardwalk. Look how far weve come from there.

Recognizing that the new technology could be beneficial to their pilots, the U.S. Army Air Corps asked another prominent American company, Bausch & Lomb, to develop glasses that would protect the eyes from the dangers of the glaring sun, when flying.

It was U.S. eyeglass company, Ray-Ban, who really ran with the concept. In 1936, using the newly available polarized lenses, and a wide frame that offered maximum protection from the sheen of an instrument panel, Ray-Ban began to produce a lens that banned the sun’s rays. Some three years later, this model of sunglass so popular with pilots, became readily available to the American public. Ray-Ban ‘aviators’ were born. And of course everybody wanted a pair.

As Americans came of age, so too did their eyewear. Throughout the war years Ray-Ban continued its working partnership with the Air Force, creating Gradient mirror lenses that managed to be both highly practical and fashionable at the same time. There was something about that American flyer in his tough brown leather flight jacket, whose sunglasses hid his eyes. Ray-Ban had just made sunglasses sexy.

Ubiquitous in the 1950’s, sunglasses became more than just eye protection. Worn by A-list celebrities in Vegas and Hollywood -stars whose every move was scrutinized and emulated all over the country- sunglasses became a fashion accessory, and Ray-Ban was quick to accommodate the growing trend for new designs and colorful frames, which they marketed to women in particular.

What Type Of Lens Is Rayban Using On Their Sunglasses

Ray-Ban uses four different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we won’t discuss here because there’s nothing special about them (they just come in different colors).

B15 XLT Lens Ray-Ban B15 XLT lenses are brownish in color, block 100% of all UV rays and allow only 15% of the visible light to pass through them (that’s an 85% reduction!). These brown lenses also offer a bit more contrast by cutting down on the amount of blue light, as opposed to a G15 lens (which is described in the next paragraph). Blue light is very easily captured by the eye and has the effect of softening other colors that are harsher to our vision. In other words, by reducing the amount of blue light, the differences between colors and brightness of objects are more pronounced.

G15 XLT Lens The G15 XLT lenses have the same properties as the B15 XLT lenses; however they’re of grayish/greenish color. The G15 lens is the original aviator lens that the military requested Ray-Ban to develop. The challenge was to design a lens that was “color neutral”; in other words, a lens that filters light like the human eye does. If you want a lens that offers a little less contrast between colors, then the G15 XLT lens is for you because it offers similar color-sensitivity to the human eye. With a lower contrast lens, the difference in color and brightness of objects will be dampened. This means that the colors you see through these lenses will be natural and soft on the eyes.

Both the B15 and G15 XLT lenses are made of impact resistant optical glass that is naturally scratch resistant. Quality and stability are remarkable and over time you will notice virtually no fading whatsoever in the color.

Polarized Lens Polarized lenses essentially cut down the amount of glare produced by reflective surfaces like water or other semi-transparent objects, and even some metallic surfaces. Glare refers to the difficulty of seeing in bright light.

Sunlight, for example, bounces off surfaces in all directions (i.e. vertically, horizontally or diagonally). For people who are active in the “horizontal plane”, it means that the bright sunlight bounced horizontally enters the eye in a similar fashion. This causes the pupils to constrict and significantly reduce contrast. That’s why drivers have difficulty seeing the road ahead of them if they’re driving in very sunny conditions (if the sun is ahead of them).

Polarized lenses have a laminated surface with vertical stripes that create a filter, which effectively cuts out the horizontally-polarized light and allows only vertically-polarized light in. In other words, if you happen to be on a clear lake you can probably see under the surface or if you’re driving, you can now see the road ahead.

Some limitations to polarized lenses are that LCD displays may become distorted or you may notice a “rainbow” effect if your car’s windows are tinted.
