When the infinity distance is within the depth of field all objects at that distance or farther will be sharp.

Definition: The farthest position (marked ¥) on the distance scale of a lens. It includes all objects at the infinity distance (about 50 feet) from the lens or farther. When the infinity distance is within the depth of field, all objects at that distance or farther will be sharp.
