Abstract: Provided is a dimming helmet visor incorporating optical shutter technology therein for instantaneous conversion from a clear state to a dark state and vice versa. These visors find utility in helmets for anyone in changing lighting conditions outdoors, especially motorcyclists. The visor's optical shutter display is connected to a photodiode and a battery with both automatic and manual adjustment functionalities. A manual on/off switch is provided for power management. The photodiode responds to light intensity above a certain threshold and switches from a clear state to dark state in a matter of milliseconds once this threshold is reached.
