Blindfold

A blindfold (from Middle English blindfellen) 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.

Blindfolds can be used in various applications:

Use of a blindfold is said to enhance the remaining senses of the wearer, focusing attention on sound, smells and physical contact. This increased awareness is said to allow for greater excitement and anticipation by eliminating visual cues, as one cannot see what to expect. It also requires trust of the submissive, with all the emotional ramifications that entails.

The blindfold has been a powerful symbol in divination and mythology since the 15th century.

In law, it is seen being worn by Lady Justice, to represent objectivity and impartiality.

The blindfold as a symbol is also a common theme in tarot and other divination methods. It can represent themes of the victim, resistance to clarity, denial, or limited views. It is often accompanied by underlying themes of integrity and truth at a cost. Likewise, the icon of the blindfold can symbolize the dichotomy of the conscious and the unconscious, as wearing a blindfold represents a stasis or a lesser state of consciousness, whereas taking off one's blindfold represents a form of awakening or rebirth. It also represents connection to feeling over senses, emphasizing the importance of emotion over perception.
