Why Polarized Lenses?
The sun is strong and can negatively affect vision and the ability to see clearly. Rays beating down on surfaces such as smooth water or a flat road reflect light that are generally horizontally polarized, as opposed to being scattered in all directions. This horizontal light creates what we call ‘glare’. And glare is not only annoying, but it can often be dangerous, especially for those who spend a great deal of time driving during the day and participating in outdoor activities.
The Benefits of Polarized Sunglasses
The good news is that a virtually invisible filter that eliminates the amount of reflecting light that enters the eye can be built into lenses, making images appear sharper and clearer. This filter polarizes the lens and is available for prescription and non-prescription sunglasses, increasing visual clarity and comfort. And polarized lenses, as well as glasses with light or neutral tints, can be worn indoors by light-sensitive people, including post-cataract surgery patients and those continually exposed to bright sunlight through windows.
Polarized sunglasses offer more than visual clarity and comfort–most provide UV protection which is important to maintaining healthy eye sight. Just as we put on sunscreen to protect our skin and our children’s skin, it’s critical that we protect adult and kids’ eyes from UV rays too.
Enhancing Your Polarized Lenses
Polarized lenses can also be used in conjunction with other features to enhance vision, such as with bifocal sunglasses and progressive lenses, and coatings like anti-reflective and anti-scratch.
These are just a few of the many great reasons to seriously consider polarized sunglasses!
