Lutein (if you know what I mean)

Robert Frost had an issue with his macula
and used barbed wire to scratch it
the regret was instantaneous
Robert had injured his macula
but Robert was not a stupid man, no
he remembered the deep coloration
he had seen on the skin of a broiler chicken

Haiku What if Lutein Could Help My Macula?
I am Robert Frost
my macula is damaged
I will try Lutein

You will not find your way with an injured macula. We've looked and looked, but after all where are we?
