When the sunlight changes, the tint changes. Each lens has a variable tint with particles that interact with the light as it hits the lens. The brighter the sun, the darker the tint. As the light dims, the tint fades, providing a clear view.
They also block dangerous UV rays and filter Harmful Blue Light, which can be found outdoors and from digital devices. These safety rated photochromic sunglasses will improve contrast and clarity, reduce glare, and darken/lighten depending on ultraviolet exposure.
