Wearing a pair of polarized sunglasses is not only important for protecting eyes from direct sunlight, but reflected sunlight as well, according to the Vision Council, a nonprofit representing the optical industry.
According to a report the Vision Council will release this week, ground surfaces can reflect and redirect high amounts of ultraviolet rays, even in the shade. Here are some examples:
Water reflects up to 100 percent of UV light.
Snow up to 85 percent.
Dry sand and concrete up to 25 percent.
Even grass can reflect up to 3 percent.
