# BG201

When the sunlight changes, the tint changes. The transition lenses on these safety glasses have 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 transition lens safety glasses will improve contrast and clarity, reduce glare, and darken/lighten depending on ultraviolet exposure. For more like this, view our full collection of photochromic safety glasses.
