Practically any pair of sunglasses also the cheap shades can make any person look cool. Old fashioned gadgets particularly are the benefits that single digit spectacles are unable to afford, such as reducing the glare on sunny or snowy days and preventing UV rays from hurting your eyes.  The need of sunglasses is essential to shield the eyes from the sun and also from harmful UV rays.  94% of the people are not aware that the sun could be just as harmful to the eyes as it is to their skin and hence the need of sunglasses to protect the eyes from the sun.

The company named Luxottica which is responsible for Ray-Ban and its iconic Wayfarers tend to have a specific recipe for the sandwiched stack of material which makes up its Sun RX prescription lenses.  Irrespective of going for a classic, Risky Business-style Wayfarer or the mirrored shades which the celebrities tend to have presently, you should ensure to protect your eyes from the sun.  At first one should ensure that your shades tend to have 100% UV protection to filter both UVA and UVB rays which is very essential in order to save your eyes.

Sunglasses with Polarized Lenses – Easy to View

One could protect their eyes further with oversized and wraparound frames which provide additional coverage in order to protect the soft tissue surrounding the eyes – that could assist in preventing wrinkles.  Ultimately one tends to have the option of deciding on polarized lenses that tends to make it much easy to view in very bright settings and could also reduce the strain on the eyes.  The following will provide some insight on the eyewear which could be beneficial to the user:

Layer 1: Scratch-Resistant Shell

Ray-Ban tends to enclose the complete lens in a layer of silicon resin in order to shield the surface from nicks and scratches, Applied through a wet-bath for unchanging coverage, the coating is said to harden due to heat and UV light.

Layer 2: Coloured Tint

Instead of tinting the lens that may result in uneven coloration due to the prescription-cutting process, Ray-Ban seems to apply colour as a separate polycarbonate layer.  The dyes mix with the molten raw material preceding moulding.

Layer 3: Polarizing Film

Light reflecting off flat surfaces like lakes and roads tends to oscillate horizontally producing glare in conditions wherein the sunglasses are inclined to matter the most. A thin layer of polyvinyl alcohol having a sequence of microscopic vertical slits stretches through the lens, revoking out the harsh light.

Layer 4: Prescription Lens  

A computer-directed diamond cutter forms polycarbonate lenses to `script-perfect magnification’. The impact-resistant material sieves vision-impairing UV light and is approximately half the weight of hardened glass common in the other shades.

Layer 5: Anti-Reflective Coating

A dark shiny surface is said to act as a mirror, particularly in bright sun and to fight this effect the invisible layers of silica oxide, titanium oxide together with zirconium oxide is said to bounce the light in diverse directions, keeping reflection of your face out of sight.
