The lenses of polarised sunglasses reduce the glare reflected off shiny non-metallic surfaces such as water, snow or wet road surfaces. They are popular amongst fishermen but now most people who spend a large amount of time outdoors have realized the benefits of polarised lenses.
Apart from boaters, outdoor fans that are benefited from polarised sunglasses might well include bikers, golfers, skiers and joggers. Polarised sunglasses provide a clearer view together with elimination of glare. These sunglasses can be used for driving as they minimize the glare from a long, flat surface such as the bonnet of the car or the road's surface. Occasionally these glasses can also be used indoors by people who are photophobic, such as post-cataract surgery patients.
