ABSTRACT:
A head-mounted visor with variable transmission has at least two zones with different values of absorption of light. Should the visor be mounted on a pilot's helmet, an upper zone designed for looking at the exterior of the aircraft absorbs more light than a lower zone designed for looking at the dashboard instruments. The application is directed to helmet equipment for tasks comprising swift passages from a very bright space to a darkened space.
