The NightFall is a clip-on blue light filter with orange lenses that clip over your existing glasses for after-dark screen use. The orange tint blocks more blue light than clear or light-yellow lenses, which is why it is aimed at evening use rather than daytime work. The small lens shape and spring hinges keep it light and easy to flip on and off. It suits people who already wear prescription glasses and want a stronger evening filter without buying a second pair.
