OK guys, I guess my attempt at dry subtle humor failed.

Hi,
 My background is in respiratory physiology and I am an aspiring amateur

trombonist.  Since playing loud and low requires huge volumes of air, I 
wonder if your fuzzy vision could be caused by hyperventilation.  When
we 
expire more carbon dioxide than we produce metabolically, the pH of the 
cerebro-spinal fluid rises, (becomes more alcaline) and this can cause 
dizziness as well as  distorted vision.    The classical remedy is to
use a 
paper bag to rebreathe your expired air and retain the CO2.  While you 
cannot do that while playing trombone try slowing your breathing rate.
