• the computer-aided optimized viewing field does not practically limit the spatial orientation of the user

• the design of the protective mask enables a correction of dioptrical defects and a compatibility with the basic military optical devices, including the noctovisor CLARA

• the hardened glass of the eye sight holes is very resistant to impacts and to scratching

• the device for accepting liquids affords a possibility of safe acceptance of liquids in a contaminated area

• easy communication and intelligibility of the speech are safeguarded by means of a sound-penetrating lining
