Why Buy Polarised?:
Light waves travel in all directions: horizontally, vertically, and on every plane in between. When light strikes a surface, some waves are reflected. The reflected light waves tend to vibrate in parallel planes. This uniform, non-random concentration of reflected light is commonly referred to as glare. Glare is not only unpleasant but is a common cause of eye strain and fatigue; it can also be dangerous because it reduces contrast and visual acuity.

Sources of glare include: water, snow, airborne water particles, dust, buildings, concrete, ice, sand, wet and dry road surfaces, and windshields.

Polarised lenses are designed to substantially reduce or eliminate reflective glare by selectively absorbing the light waves travelling in all directions except the vertical plane. The term "polarised" is used to describe light that has passed through a polarising filter. As a result of passing through the filter, the transmitted light travels in a uniform pattern.

Ordinary darkly tinted sunglasses do not remove glare and may reduce vision by limiting the amount of light entering the eye. It is not necessary to apply additional tint to polarised lenses because performance is gained by cutting glare and allowing a greater transmission of light. This results in better overall vision.

The exclusive ZB-13 POLARISED blended ‘sepia' lens colour soothes your eyes, enhances vision and allows for your eyes to adjust to the always-changing light conditions. It provides the optimum blend of contrast, clarity and light transmission for all day COMFORT for your eyes.

The layered polarised lens filter cuts out the glare experienced with outdoor environments and means enhanced vision in a wider range of conditions.
