The IR-clip allows you to switch between the IR-lenses (IR-light & IR-dark). They also make it possible to wear prescription lenses in the frame and select your desired IR-lens shade depending on the lighting conditions.
A useful combination is to have IR-light lenses mounted in the frame and the IR-dark lens as your additional clip-on. They work well together. The IR-clip is specifically designed to fit IRpair, Phantom & Ghost.
