ULTIMATE EYEWEAR LTD PRESENTS POLAR PLUS…
ADVANCED POLARIZED LENS PROTECTION FOR YOUR EYES.
How Do Polarized Lenses Work?
Light from the sun usually scatters in all directions but when it is reflected from any flat/horizontal surface (roadways, water, car bonnets/bumpers etc), it tends to become polarized – meaning it travels in a more uniform (usually horizontal) direction.
This creates an annoying and sometimes dangerous intensity of reflected light that causes glare and reduces visibility.
Polarized lenses are manufactured to contain a special vertically positioned laminate filter that blocks this type of intense horizontally reflected light.
This reduces unwanted glare while allowing the useful vertical light through to your eyes.
Benefits Of Wearing Polarized Sunglasses
Polarized lenses have many benefits.
They eliminate the harsh glare from the sun and help enhance colours and contrast, leaving a remarkably crisp field of vision.
Not only do polarized lenses reduce eye strain and make for safer driving and boating, they can also improve visual clarity and enhance perception of colours.
Migraine sufferers also claim that polarized lenses help reduce the onset and intensity of headaches.
Not All Sunglasses Are The Same
Firstly the difference between polarized sunglasses and normal sunglasses is that polarized lenses selectively eliminate the wavelengths of light that cause glare, while normal sunglasses absorb all light wavelengths equally, thereby allowing annoying glare to enter your eyes.
When considering different types of polarized lenses, it is also important to know that not all polarized lenses are the same.
Inexpensive polarized sunglasses differ from more expensive lenses in significant ways. Cheaper lenses may only have a thin chemical laminate on one side of the lens which only provides minimal benefit and the thin layer can be easily rubbed or scratched off . These lenses are usually mass produced and of low quality and show aberration in the lenses.
Higher quality options have film laminated between two layers of lens material. Encasing the laminate protects it from being scratched and provides additional benefits. The thicker the polarizing film, the more protective the lens is against glare.
Even here there is variation in quality as essentially there are two types of polarizing films used : 0.75 mm and 1.1 mm. The 1.1 mm layer is more expensive and provides additional strength and scratch resistance than the thinner film.
Polar Plus adopts the latest technology where a quality 1.1mm polarized film is integrated into the lens material itself , providing maximum protection as well as preventing de-lamination that sometimes occurs with other polarized lenses.
Polar Plus also provides 100% UVA/UVB protection and comes in different colours as well as with or without an additional mirror coating.
