Help on adding effects to clothing

I have been tinkering with the armor and item json files and I made a new effect. It is valid, but i do not know how to add one to clothing. I was trying to make a blindfold that removes all vision. Any help is appreciated
Ex:
{
“type” : “ARMOR”,
“id” : “blindfold”,
“name” : “Blindfold”,
“name_plural” : “Blindfolds”,
“weight” : 100,
“color” : “light_gray”,
“covers” : [“EYES”],
“to_hit” : -1,
“storage” : 0,
“symbol” : “[”,
“description” : “A blindfold, use to blind yourself.”,
“price” : 100,
“material” : [“cotton”, “null”],
“volume” : 1,
“cutting” : 0,
“warmth” : 0,
“phase” : “solid”,
“environmental_protection” : 1,
“encumbrance” : 2,
“bashing” : -4,
“flags” : [“SKINTIGHT”],
“coverage” : 100,
“material_thickness” : 2
}

Make a flag that causes the item to have that effect when worn.

See: Night vision goggles and its flags for reference.

Thank you. This is very appreciated.
