Your outdoor environment is composed of several wavelengths of light, some visible and some invisible. It is known that too much of anything can be bad, especially UVA and UVB (Ultraviolet Light). High Energy Visible or (HEV) light can be good and bad depending on the amount of direct exposure over a period of time.
If your exposure to any of these wavelengths of light is excessive you could cause damage or stress to your eyes. Our light and glare reduction eyewear are coated to reduce the exposure of UVA UVB UVC HEV by filtering out both natural and artificial lighting.
