Eyeglass Isle is a location from The Legend of Zelda: Oracle of Ages. This island is found in the northern Zora Seas and roughly resembles a pair of eyeglasses. It is home to the Eyeglass Isle Library, which is only opened by using the Library Key on the keyhole in the past. Located inside are many Old Men who tell Link of the surrounding seas and the Fairy Queen, who has recently gone missing. In the past, they also speak of a Fairy Powder located in the back, but say that it is unreachable due to the missing Book of Seals. After obtaining the book from the present library, Link can navigate the maze in the back room to obtain the Fairy Powder. Located in the western area on the island is an Octorok who asks Link to give the Fairy Powder to her. Upon doing so, she turns back into the Fairy Queen and cleanses the Zora Seas.
