    How Do Polarised Lenses Work?

    Light reflected from surfaces such as a flat road or smooth water generally is horizontally polarised. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare. Polarised sunglasses cut glare and haze so your eyes are more comfortable and you can see better.

    Polarised lenses contain a special filter that blocks this type of intense reflected light, reducing glare.

    Though polarised sunglasses improve comfort and visibility, you will encounter some instances when these lenses may not be advisable. One example is downhill skiing, where you don’t want to block light reflecting off icy patches because this alerts skiers to hazards they are approaching.

    In addition, polarised lenses may reduce the visibility of images produced by liquid crystal displays (LCDs) or light-emitting diode displays (LEDs) found on the dashboards of some cars or in other places such as the digital screens on automatic teller machines and self-service gas pumps.

    With polarised lenses, you also may be unable to see your cell phone or GPS device.

    Boaters and pilots also have reported similar problems when viewing LCD displays on instrument panels, which can be a crucial issue when it comes to making split-second decisions based strictly on information displayed on a panel. (Some manufacturers of these devices have changed their products to solve the problem, but many have not yet done so.)

    However, for most other sports and activities, polarised sunglasses offer great advantages. And today, many polarised lenses are available in combination with other features that can enhance outdoor experiences.
