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. It can be worn when the eyes are in a closed state and thus prevents the wearer from opening them . While a properly fitted blindfold prevents sight even if the eyes are open, a poorly made or trick blindfold may let the wearer see around or even through the blindfold.
