F

is for the flashes of lights i've been seeing in my right eye.
is for floaters that might have been floating in my right eye.

and they're signs and symptoms for retinal detachment.

F is for the word that comes out too late as my numbskull tries to understand it all.

what are you trying to tell me, Lord? i've been keeping off contact lens. i'm doing things everyone's doing, from rubbing my eyes when i'm tired, to staring at the computer because my job requires it. am i to be singled out again when all i want is the same things others want? are you going to take my sight from me now? 

i'm sorry, Lord, if this is all i can think of.
