UV protection is a critical factor when selecting custom sunglasses, especially for bulk orders, as it ensures wearer safety against harmful sun rays. The best UV protection is UV400, which blocks 100% of UVA and UVB rays, providing comprehensive eye safety. Most high-quality sunglasses, like the Rainbow Frame Sunglasses, Polycarbonate Sunglasses, and Metal Aviator Sunglasses, feature UV400 lenses.
