After you put it on, 4 rods with a padding on the ends will retract from the helmet, then each rod is going to start to create a strong suction on each eyelid by putting pressure, and it is going to stick to the eyelids, and then the rods will pull your eyelids away from the center of your eue until it reaches the point that your eyes are uncomfortably stuck open. You can't take it off or stop it from keeping your eyes open. Every minute the helmet will squirt water into your eyes.
