There were three women called 'The Graeae' who were blind and with one eye each could predict either the past, present or future.
No, they all have their own eyes. You are thinking of the Graeae, three archaic goddesses, daughters of Phorcys and Ceto. They looked like old, grey-haired women and had only one eye and one tooth to go between them.
A Swan. Weird, I know, but that's her symbol. Just some extra information, she was part of the Graeae (Graiai), a group of three women who were born old and kept aging. "The Graiai were usually depicted as old crones. However according to Aeschylus they were Seiren-shaped monsters with the head and arms of old women and the bodies of swans."
The graeae live in a cave
Graeae Theatre Company was created in 1980.

The Graeae (English translation: "old women", "gray ones", or "gray witches", alternatively spelled Graiai, Graiae, Graii), were three sisters who shared one eye and one tooth among them.
Their name means "The Gray Ones." Poets have described them as having had gray hair from birth and having the body of a swan. They had one eye and tooth that they shared between them. They were the sisters of the Gorgons, being daughters of Phorcys and Ceto.
No. You're thinking of the Graeae, who shared one tooth and one eye among them. By stealing their eye, Perseus forced them to tell him the whereabouts of the items he needed to kill the Gorgon, Medusa (or in later accounts, the location of Medusa herself).
