Reasons Why Polarized Sunglasses Give Total Eye Protection

There has never been so many different types of sunglasses to choose from, especially if you are savvy enough to intend buying glasses online. Yet, when you browse the extensive range of designer glasses in the current season fashion styles, it is important to remember that their primary function is to protect the eyes from the sun's harmful radiation!

Without doubt, the safest form of protection, whether you are buying prescription sunglasses or opting for budget conscious cheap designer glasses, has to be polarized lenses.

Carefully assembled with 7 functional elements intricately bonded together, the main element of the sandwich-lens construction is the polarizing light filter in the centre manufactured to rigorous LCD industry standards

It is always important to carefully examine the specification, which is recommended to be UVA 400 for best all-round protection against the different types of wavelength radiation penetrating the earth's ozone level.

For this purpose, UV light absorbers are laminated to both sides of the filter to block the three potentially harmful light rays, i.e. UVA, UVB, UVC. This is in addition to the important elimination of glare.

Optically-corrected, shatter-resistant cushion elements are then laminated to both sides of the UV absorbers. They provide greater protection than acrylic lenses, which may fragment on impact and also make the lens material lightweight, flexible, impact-resistant and most importantly, safe for medium-impact sports, driving, outdoor activities and everyday urban life.

A polarized lenses resistance to impact protects the entire surface area around the eyes , transferring any energy absorption to occur to the frame and the head. A polycarbonate lenses would only offer only low energy absorption.

Finally, a durable scratch-proof finish is applied to the polarized lenses to ensure that lens performance is itself protected to retain their high optical performance from accidental damage, either when worn or not in use.

Polarized lenses may be considered a remarkable feat of engineering, intended to serve as vital eye protection, and should rightly be a factor in deciding which of the latest look designer name frames are to be this year's fashion accessory.
