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. ==Applications== Blindfolds can be used in various applications: * As a sleep mask: They block out light when sleeping, especially during air travel, or for those who sleep during the day, given that shutting out light allows the user to achieve a deeper level of sleep. They can also provide relief from claustrophobia for magnetic resonance imaging (MRI) patients. People with glaucoma should avoid using these. * In children's games, such as Pin the Tail on the Donkey and when hitting a piñata. * During both martial arts and weight lifting, to encourage reliance on other senses, such as touch or hearing. * As a sensory deprivation tool in meditation, to focus attention on oneself rather than outside imagery. * As a way to keep a kidnapping victim, hostage, prisoner, etc., from being able to identify locations or people. (A hood is a common alternative.) * To cover the eyes of a blind person for health or cosmetic reasons. (Since the invention of sunglasses, this is much less common.) * As a prop in magic tricks. One common trick involves a blindfolded performer doing a task that requires vision, such as driving.〔(The News Today Online Edition, ''Of entertainers and blindfolded drivers'' ) by Atty. Cyril Regalado (retrieved July 31, 2011)〕 * As an aid to simulate blindness during training of Orientation and Mobility Specialists, so that they develop empathetic understanding of blindness and learn how to rely on their other senses to get to know the environment and move around freely and independently. * During executions.To relax the accused as she will be unable to see her execution. Its regarded as humane to blindfold. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「blindfold」の詳細全文を読む スポンサード リンク
