blindfold

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.
