A:
A. Strap Length
B. The optical waveguide AR glasses are installed on the safety
goggles, and the AR glasses position can be adjusted by adjusting the
AR glasses arm. (As the space for extending and retracting of the AR

adjustment range, the AR glasses should be adjusted after the helmet
is removed. And after adjustment, the safety goggles should be
extended or retracted for several times to test whether collision occurs.

according to the actual head shape.
