- Polarized lenses reduce the glare of light bouncing off of water, highways, or other reflective surfaces.
- Various lens tints can also help to reduce some forms of light. Gray reduces brightness, but not color. Brown or amber reduces glare, but distorts color. Yellow reduces the haze of blue light, which sharpens the view but distorts colors. Green reduces glare, filters out blue light, and provides contrast between objects. Rose provides contrast for objects viewed against blue or green backgrounds.
- Shoppers should compare the weight of various sunglasses until they find a pair of shades that her or she is comfortable with. Heavier pairs of glasses can cause headaches by putting too much pressure behind the ears.
- With proper care and cleaning sunglasses can last you for quite some time. To keep sunglasses clean gently wash with water and a grease-cutting dishwashing detergent. When they feel squeaky clean carefully dry with a clean, lint-free cloth.
- Lastly, in addition to keeping sunglasses clean, owners should also store their sunglasses in a protective case when not in use.
