How do I activate an end portal?

The 0.9.5 update is out with a new block called the End Portal. But, I still can't figure out how to activate it and go to The End. Some videos in YouTube told me that I need ender eye, but I can't find it in the creative inventory.

The Answer bellow relates to versions before Alpha 0.12.1, before the Nether was introduced. the Question asks about Alpha 0.9.5

Going by the Version History the End Portal Block was added in 0.9.0 and according to the history for the block they can not be used to access The End, probably because (to my knowledge) even in the current version of 0.10.4 (at the time of writing) for Pocket Edition...

• The Eye of Ender hasn't been added and neither has it's parent items, the Ender Pearl and Blaze Powder (because there is still no Nether and the Nether Reactor does not spawn Blaze Powder).

• The End itself does not exists in Pocket Edition

In the PC Edition. the End Portal Block (or Frame) is naturally generated inside Strongholds in the formation they need to be in order to be able to open a portal to The End (5x5 Square Ring)
