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. Polarized lenses are mainly gray and yellow.

There are some disadvantages to polarized lenses. When trying to view an LCD TV or some touch screen displays, the screen may seem to disappear at certain angles. According to Perfect Glasses USA, this means that polarized lenses are not a good choice for an airline pilot or any profession that relies on LCD or touch screen displays. Photographers may find it impossible to see through the lens of the camera at certain angles as well. Although polarized lenses remove the glare from snow, skiers and snowboarders do not like to use them because they depend on light variations to see ice, hills and bumps.
