It takes the human eye quite a while to adjust to the dark...maybe even as long as an hour...so red electric lighting was used within submarines, along with red tinted lenses, to assist in the adjustment for the crew members.

The Germans also deployed some early inferred equipment , both on tanks and halftracks . Also an early type of night-scope was used or in the testing phase for the individual soldier . Could these have any connection those projects , just a thought . I have a pair of Allied googles with red lenses .
