You’ve probably heard of glare before but if you haven’t, you’ve most probably experienced it at some stage. Glare is caused by light from the sun being reflected off of a shiny surface, for example water or snow. When the sunlight reflects off of the surface it has hit, it’s magnified as it shines back into your eyes – this is glare.
The best way to prevent glare is to wear polarised sunglasses. These lenses have been coated with a special chemical film that not only neutralises glare, but also reduces the amount of UV rays your eyes are exposed to, all whilst helping you to see more clearly.
You may think that a little glare is nothing to worry about. However, it can actually be more dangerous than you might think. Glare can reduce depth perception, as well as distort your view, affect the appearance of colour and in some cases, temporarily blind you. Now imagine you’re skiing, you experience glare and miss that icy patch of snow you’re about to hit…
Many people think that regular sunglasses will prevent them from experiencing glare; unfortunately that is not the case. Untreated sunglasses are designed to reduce the amount of light that enters the lens horizontally and vertically. Polarised lenses on the other hand absorb horizontal waves, only allowing vertical waves to pass through the lens. And as light only travels in one direction through these specialist lenses, glare is eliminated.
Finally, it used to be fishermen and women, water athletes and snow-sports enthusiasts that used to benefit most from polarised lenses. Today however, they’re recommended for a number of other individuals including joggers and runners, golfers, and those who simply enjoy spending time outdoors.
