theropod sunglasses?

   Hi everyone,

   I'm new here, so don't bite.
   I am rather surprised I haven't heard this before, ( has it been 
mentioned?) but I think the big hornlets above the eyes if the large 
theropods ( Allosaurus, Carnotaurus, etc...) could have been used to 
block out the Mesozoic sun.  Today's sidewinder snake has adopted 
similar protrusions above its eyes and they seem to do just fine at 
protecting the eyes from the sun.  Does anyone think this is a valid 
idea?
