If you use salt in the CS for your eyes you can bring it to a saline level 
similar to tears to avoid the dryness/stinging.  The distilled water you make 
the CS with is the cause of the 'stinging'.

  Thank you.  I use an eye dropper to drop CS into my eyes.  I am not sure that 
it helps all the time with dryness.  If I do not use cs for awhile it sort of 
stings a bit when I begin using it again.  Faith G.
