Description
State whether the PTW driver was wearing photochromic sunglasses, as according to the on-scene evidence, the rescuers/police statement or the victim/witnesses interview.
Photochromic lenses are lenses that darken on exposure of ultraviolet radiation.
Once the UV is removed (entering lower light areas) the lenses gradually return to the clear state.
