EyeQusa as well as many other eye wear manufacturers have been using polarized lenses for many years because they know how these lenses can reduce the glare of the sun. These days most outdoor sunglasses and eyewear are made using polarized lenses because of the fact that they are so beneficial to many outdoor enthusiasts but it was a different storey a few years back when it was only fishermen or boaters who used them. So how do polarized glasses differ from traditional glasses; what are they?

 

It is important to understand the way in which light travels if you want to be able to understand polarization. Light will travel normally in a direct and very focused manner. When light scatters and diffuses it is due to external influences. If light is reflected on a pavement, water or snow then it is travelling a very direct and horizontal path and it will be much more intense. So when light is reflected off these surfaces, glare will develop. If you want to reduce this glare then it is necessary to scatter the light by using a filter.

 

This is exactly what polarized glasses will do. The intense wave of light that we know as a glare is taken and diffused across the lens into patterns unrecognised by the eye. With polarized glasses the glare is reduced and it means the person wearing the glasses will see much clearer and with more detail. But the problem with polarized glasses is the fact that they will not be appropriate for every sitation.

 

One instance is with downhill skiers who need that glare to indicate where any ice patches are on the path in front of them. Polarized lenses might affect the ability to see these ice patches and this could make it very dangerous. It is also worth noting that polarized glasses can affect a person’s ability to see their digital display in their car when driving. It can also be hard to make out the display on some watches, smart phones or music players that are using LCD screens.

 

Now that you know all about polarized glasses you can make a wise decision in purchasing your next pair. Remember that eyeQusa makes some of the finest eye wear available; both polarized and non-polarized.
