Extending to the farthest possible point, as of that which one can see in the distance. Sometimes used hyperbolically, humorously, or sarcastically. I love this part of the country. The green hills stretch out as far as the eye can see. My father was always so proud of his little shop. When I was a boy, he'd take me to the roof and say, "One day all this will be yours, as far as the eye can see."
