Eyes are the mirrors of the heart. However, more scientifically speaking, eyes are more like windows to our brains and as neuroscientists say, they can find out mental exertion by calculating the variations in pupil diameter. Looking into someone’s eyes can be extremely disturbing to both you and/or to the person being looked into who may not want to reveal his internal feelings.
If you have been hurt, or crying, a pair of good sunglasses can be a perfect cover to hide the revealing reddish eyes, marks of weeping and bruises. Dark shades not only succeed in concealing freckled skin, by blocking direct eye contact, it can drastically transform face-to-face communication. Instead of the vulnerability of direct eye contact, the dark shades can inspire awe. If one cannot see how your eyes are reacting, one naturally becomes defensive and nervous. However, it is sometimes taken to be rude gesture to keep wearing sunglasses if the person you are talking to is not wearing one and your persistently carrying on with the shades can be considered as an insult.
The selection of sunglasses is greatly influenced by the fashion in vogue, advertising in TV and by the celebrities, who serve as fashion icons, sporting ‘cool’ shades. Styles in sunglasses may vary from conventional shades to absolutely wild and outrageous ones and comes in every imaginable color. There is a certain charisma when one puts on sandglasses.

Lenses of a sunglass come in various shades and hues. They may have solid colors or they have a gradient tint where the upper edge of the glass is darker in shade than the lower portions. But the most important feature to look for while buying a sunglass are its transmittance quality and optical properties.
o The kind of tint or differentiation in shade determines the parts of the light range that the lens is capable of absorbing. The use of different colors, hence, is made for generating specific effects.
o Grayish tints are the classic all-purpose tints that help to optimize the entry of light, control overall brightness, and causes least amount of color distortion. Gray lenses are good protectors against bright light or glares and are thus great to put on during driving or general use.
o Yellow or orange tones help to reduce the effect of blue light while letting in greater percentage of other lights. As blue light has got a tendency to deflect and disperse off a lot of things, it can lead to a sort of glare known as blue haze. The yellow shade efficiently removes the blue part of the spectrum and has the ability of bringing everything bright and sharp focus. This is the chief reason why snow glasses are generally yellow or orange colored. This tint distorts color sensitivity and so, is inappropriate for any action that is color-oriented or color-dependent.
o Amber and brownish shades are also great all-purpose shades and can be worn on any occasion. They decrease the glare and have molecules that absorb upper frequency colors such as bluish lights and also UV rays. Research has discovered that over-exposure of eyes to near-UV light frequencies like blue, indigo or violet leads to enhanced formation of cataracts. These tints also deform colors quite like yellow lenses but provide better contrast and clarity.
o Green shades sieve some blue light and also lessen the glare. As green lenses offer maximum clarity, contrast and visual sharpness, it is the most popular tint in use.
o Purple and rosy tints present the best contrast of articles against green or blue surroundings. They are the best option for hunting or water skiing.
