What about if I was the size of a carbon atom?
A) this makes no sense. The complexity of a human being can not be expressed by any known particles on such a scale.
If you had a mass that tiny, a photon would hit you like a bus. Photons carry momentum proportional to their energy, and if your mass is small enough, then the absorption of that momentum will noticeably accelerate you.
Even if we could magically shrink a human to that size... we have all kinds of other considerations in how quantum mechanics deals with the very tiny... assuming we could somehow break physics for only you to be so small, with all your normal particles masses and charges... then we can't at all talk about how something from outside that physics-space interacts with you.
What happens to the "normal" photon when it enters your "tiny" eye? Does the normal photon become tiny, so that you can see it, or does the normal photon basically wash right past you, since you are far too small for it to interact with, and you have no significant conductive properties... and even if you were electrically charged, your mass is such that it can't easily impart it's momentum to you by waving you violently in a transverse manner... so it might not interact with you at all.
It's a dead end.
Things that are so tiny can not have "eyes", much less a mind capable of interpreting chemical stimulus as vision.
Can you reformulate the question into something that doesn't break physics in the assumption?
