The sight of a man is only one of their senses. Sight, hearing, smell, taste, touch together help us to perceive the phenomenaof the world around us. Touch, sense of body movement and holding are together the somatic sensor system.
Our sight is undoubtedly an important means of perception, but without the help of our somatic sensors we would not make it either!
For instance:
the musician is not looking at the instrument while playing,
we do not look at the pedals while driving,
while doing sport activities, we do not look at the tools all the time.
Migrating birds sense magnetic field.
