SIGHT is what you see with your Eyes;
VISION is what you see with your Mind.
HEAR with your Ears;
LISTEN with your Heart.
Nice... BUT... don't forget that it's simply 'Rhetoric'.
Sight & Vision actually mean the same thing and are actually interchangeable but in recent times people have rhetorically tried to separate the 2 quite effectively actually. But in reality, although they mean the the same, the difference in the 2 seem to be gaining momentum... and I do like the distinction that their division is making... so yeah, they're different after all!
Rhetoric is the art of effective or persuasive speaking or writing, especially the exploitation of figures of speech and other composition techniques. Although designed to have a persuasive or impressive effect, but is sometimes regarded as lacking in sincerity or meaningful content... sometimes.

Here's an interesting take on Sight & Vision:
EYECARE: THE DIFFERENCE BETWEEN SIGHT AND VISION
EYESIGHT essentially refers to the physical attributes and performance of the many organic components involved in the visual system. 20/20 vision is a commonly quoted measure of normal vision, yet it simply describes the sensitivity of the eye to see fine detail in the distance.
Unlike eyesight, VISION is a thought process, which emerges an understanding of what is seen, where it is and how to react to it. It combines information from many sensory systems to create a perception of reality. Vision describes a more dynamic and interactive process, essentially a whole information processing system developed through experience to gain understanding of the external visual space world.
For example, in a person driving a car, vision is much more than reading license plates clearly at a distance. Vision is the total process whereby the spatial relationships between the cars are taken in and processed by the driver in order to guide the car safely to its destination, without an accident and with minimum stress. Vision judges the relative speeds of the other cars, and alerts the driver to a pedestrian stepping onto the road or another car at an intersection, or the door of a parked car opening.
Vision is what directs the baseball player to swing the bat at the exact right moment and place in space to make contact and hit a home run.
