POLARIZED LENSES
Polarized sunglasses reduce reflections. Reflection is when the sun's rays are reflected into your eyes from water, snow or glass. You won't be completely blinded by the reflection, but you will have to squint your eyes, which will strain them. Polarised sunglasses help you see details more clearly. It can improve performance and prevent accidents. Your eyes will also not get tired as quickly.
HOW DO POLARISED LENSES WORK?
It is important to understand what light is polarised and what is not. When you light a match it emits non-polarised light. The light comes from random angles in all directions.
Polarised light is created when light is reflected from something, like water or the bonnet of a car, and comes horizontally towards you. This horizontal beam of light causes reflection. This reflection can be dangerous, especially when driving a car or walking on snow.
A special chemical is laminated horizontally onto the lenses and makes the lenses polarised. This pattern blocks the light that comes in horizontally and thus prevents reflection. Light only passes through the polarised lenses in one direction, thus making use of only the light coming in vertically.
BENEFITS OF NON-POLARISED LENSES
- Less eye strain - no eye fatigue
- Better and more detailed vision
- Colours appear clearer and brighter
- Safer operation on water, snow and in traffic
POLARIZED LENSES ARE INTENDED FOR:
- For driving - For driving, low winter sun and sudden reflections are no longer a distraction
- For snow - much more pleasant to do winter sports on snow and to walk on a sunny day
- On the water - You can see the surface and contours of the water more clearly. You don't have to squint all the time
