Yes. The sun emits damaging ultraviolet (UV) rays that can damage the eyes. And UV rays penetrate clouds, so you can get sun damage to your eyes even on overcast days.
Ultraviolet (UV) rays are high-energy, invisible light rays; sunlight is the main source of UV.
UV light is broken into three different types: UVA, UVB and UVC.
● UVA has longer wavelengths and passes through glass easily; experts disagree about whether or not UVA damages the eyes.
● UVB rays are the most dangerous, making sunglasses and sunscreen a must; they don't go through glass.
● UVC rays do not reach the Earth because its atmosphere blocks them.
All of our sunglasses have a 400 UV protection. That means our sunglasses block light rays with wavelengths up to 400 nanometers, which are some of the tiniest UV rays. This includes UVA, UVB and UVC rays.
