Polarized sunglasses are specialized eyewear designed to reduce glare from surfaces such as water, snow, and glass. Glare has a tendency to distort the true color of objects and makes them harder to distinguish.? Polarized sunglasses are especially useful for certain sports and driving, helping participants to see more clearly and avoid potential hazards. UV400 lenses provide 100% UVA & UVB protection. One size fits most adults. Available in black and navy blue.
