Trivia

 * The Blindfold is the only Ankh Charm material that is visible when equipped.
 * A real-life usually disables the wearer's sight instead of preventing sight-deteriorating effects.

 * In Terraria, the character may be using the blindfold to "see without using one's eyes," which would negate any visual impairment.
