Sunglasses Are More Than Shades
Sunglasses have gone from a fashion accessory to a necessity. You depend on them for driving, recreation and most outdoor daytime activities.
When choosing your sunglasses, you probably still look for a fashionable frame but, more importantly, you should be seeking lenses to meet your eyes' needs for comfort and protection.
Factors you will want to consider are your eyes, your lifestyle and your personal preferences.
In addition to visible light, the sun has two invisible forms of radiation: infrared (IR) and ultraviolet (UV).
Your eyes' natural infrared protection is generally sufficient under normal outdoor seeing conditions. Your UV protection may not be.
