Stellar Parallax

I see you through my left eye

And when I move two inches to my right

I see you through my right eye

I see your face clearly in my vision

I know how far away from me you are

I see your left side with my right eye

I see your right side with my left eye

You are three inches high and one inch wide on the screen of my

mind

The light that you shine takes its time getting to my eye

Traveling always at the speed of light

A light reflected, refracted and rearranged

According to what strains of elements you contain and emanate

But what are you?
