What is UV Light?
Ultraviolet, or UV light, is electromagnetic radiation from the sun. We can’t see it, but it penetrates the earth’s atmosphere and reaches your skin and eyes in the form of UVA and UVB waves. These harmful rays can do damage in any season and in any weather, not just direct sunlight.
Investing in sunglasses which are rated as UV400 blocks 99 to 100 percent of UV light. This rating ensures that all light rays with wavelengths up to 400 nanometers, including both UVA and UVB rays, are blocked out. All of our stylish frames styles carry the UV400 rating. The UV protection is built into the lens, so it won’t fade or disappear over time.
