The Eye of Ysera, often just shortened to "the Eye", is a place within the Emerald Dream. From the Eye, the green dragonflight - and Ysera herself - watch over both the dream and Azeroth. It was founded shortly after the creation of Azeroth (and thus also the Emerald Dream) when the green dragonflight was charged with their task of protecting both realms. The other green dragons honored Ysera by naming the Eye after her.
