A blindfold is an item of clothing or material used to cover the eyes, usually as a means of preventing sight. It can also be used as a form of sensory deprivation, allowing the wearer to focus on other senses such as hearing and touch. The term 'blindfold' is derived from two words: 'BLIND' and 'FOLD'. The word 'BLIND' refers to the inability to see, while 'FOLD' refers to the way the material is folded over the eyes. The term 'SCREEN' is related to the concept of a blindfold, as it is a barrier that prevents something from being seen. In this case, the SCREEN is used to prevent the wearer from seeing what is in front of them.
