I think seeing happens partly through the eyes, but not entirely.
Thus there is no doubt the eye was intended for us to see with.
Drawing is based upon perspective, which is nothing else than a thorough knowledge of the function of the eye.
There's a reason why I use film. It's because it's the best representation of how our eyes work. I really believe that. I think it's better than digital.
The eye is the window of the human body through which it feels its way and enjoys the beauty of the world.
Your eyes is camera and your brain is a file cabinet.
The eye doesn't see any shapes, it sees only what is differentiated through light and dark or through colors.
The human eye has long fascinated lovers, artists and physicians. The ancient Greeks dissected eyes, but struggled to understand how they worked, unclear as to whether they received or emanated light.
The eye and brain are not like a fax machine, nor are there little people looking at the images coming in.
The eye transmits its own image through the air to all the objects which face it, and also receives them on its own surface, whence the "sensus communis" takes them and considers them.
The eye - which sees all objects reversed - retains the images for some time.
The question of how the eye works - that is, what happens when a photon of light first impinges on the retina - simply could not be answered at that time.
