What is Polarized Sunglasses?
Polarized sunglasses are specialized eyewear designed to reduce glare from surfaces such as water, snow, and glass. Glare distorts the true color of objects and makes them harder to distinguish. Polarized sunglasses can be useful for certain sports and driving, helping participants to see more clearly and avoid potential hazards.
How Polarized Lenses Work
Polarized lenses are available in a variety of colors, depending on the material from which the lenses are made.
Darker colors provide higher levels of polarization.
Sunlight can be absorbed or reflected in several different directions. Sunlight that is bouncing off horizontal surfaces such as water, land, or the hood of a car is usually reflected back in a similar horizontal direction. This reflection produces an agitating source of glare that cannot only create visual discomfort but can also cause a potentially blinding glare. Glare has the potential to create a very dangerous situation, especially while driving. Polarized lenses contain a laminated filter that allows only vertically oriented light to pass through. This blocks the horizontally oriented light so glare is almost eliminated.
The most common colors of polarized lenses are gray and brown. However, depending on the manufacturer, many other colors may be available.

Advantages of Polarized Lenses
A high-quality pair of sunglasses will usually include polarized lenses. A polarized lens offers the following advantages over non-polarized lenses:
- Improves visual comfort
- Improves contrast and visual clarity
- Reduces eye strain
- Allows for the true perception of colors
- Reduces reflections and eliminates glare
