A blindfold (from Middle English '''') is a garment, usually of cloth, tied to one's head to cover the eyes to disable the wearer's sight. While a properly fitted blindfold prevents sight even if the eyes are open, a poorly tied or trick blindfold may let the wearer see around or even through the blindfold.
