Eyeglass Isle

Eyeglass Isle is a location from The Legend of Zelda: Oracle of Ages. This island, shaped roughly like a pair of eyeglasses, is found in the northern Zora Seas. It is home to the Eyeglass Isle Library, which can only be opened by using the Library Key on the keyhole in the past. Inside are many Old Men who tell Link of the surrounding seas and of the Fairy Queen who has recently gone missing. In the past, they also speak of a Fairy Powder 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 and obtain the Fairy Powder. On the island just to the west 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.
