Conal Ejection

I get two different shades
One for my left
And one for my right

And it serves me proper too
For staring into the sun all day
With one eye closed
The other sucking in all the UV rays
Damaging the retina beyond all recognition
Rounding up the cones for the rod's personal gratification
Soon having all the conical fellows in one small place
Surrounded by rioting rods
A blur of black and white motion
Rotation counter clockwise around one spot of kaleidoscope color

Fearful for their function
The cones activate their superpowers
Touching one another and being thrown back
A Wonder Twins move if I ever saw one
Transforming all at once into a literal rainbow
Projecting straight out the forward lens
Then arcing downward in an attempt at a circle

Though that'd be silly if achieved
For no entrance would be attained at the back of my head
And all it did was produce an exclamation from my lips
"Oh look! A rainbow!" and a point and gawk with childish delight

That left the right eye
The one that'd stared at the sun for so long
Without a cone to its name
And a black and white outlook from that day forth

So now when I look around at the world
One half sees colors as it should
And the other
Sees more like a dog would
