Does an eye "absorb" a proton?

So I am looking at the sky, at all the ancient stars.  And the photons from those stars may have travelled for thousands of light years to get to me.  When the photon strikes my retina, and alters (I think) the molecules, is the photon converted to energy and is now more or less a part of "me"?.  Every time I look at the night sky, am I taking on a little more of the heavens, no matter how slight?

*edit: typos*

*edit: I know I typed proton in the title, I derped, I meant photon*

Yes, this is an accurate description of the absorption of photons by the retina.  

They've traveled a very long distance for a very long time (in your frame of reference) to reach you.  Once they hit one of the rods or cones of your eye, they convert to a chemical form of energy which is transmitted to the brain.  

Note: Your title has a small typo.  Photons and protons are distinct.
