"A person with impaired vision obviously does not 'see' the same as a person with perfect vision. Yes!
But they can 'perceive' it in the same way!"
vayama, because of that, based on that person's (with impaired vision) will have a different interpretation of what he is seeing.
My whole point is, a person's perception of reality is, to a cery large extent, influenced by his 5 faculties.
