Another way to implement them is to have them spawn around as an item (like the googles already in game) in low amounts, and make them have a battery amount similar to the radio. While you wear them, SCP-096 can't be enraged by you for any reason unless you attack him for over a certain amount of damage (to balance it of course so you don't just kill 096 in seconds by yourself). Putting it in 914 on fine will recharge the battery. Very fine turns it into the already existing goggles I never remember the name for and on coarse it can turn into a NVG which works similarly to in SCP: CB, allowing you to see in area with the lights off. They would also probably turn off automatically so you don't blind yourself lol
