Sunlight can be reflected in many directions off of horizontal surfaces, such as water, land, wet roads and the hood of a car. These horizontal reflections create a glare that can blind a driver, causing an accident. According to Perfect Glasses USA, polarized lenses are good for people who drive for a living and need to see well at any time of the day. People who like to fish or boat appreciate polarized lenses, as the lenses remove the glare and help the fisherman see fish or spot rocks that might damage the boat.
