Yes! Our sunglasses block 100% UVA/UVB light. According to The Vision Council, the sun emits UVA, UVB, and UVC. The Earth’s atmosphere absorbs UVC rays, but UVB rays are not fully blocked and can still burn the eyes and skin. The most harmful rays (according to the World Health Organization) are UVA rays, which are not blocked by the atmosphere and are responsible for the most damage to vision health.
