Natural Cures for Blepharitis

I tried putting castor oil in my eyes for a couple weeks. At first, I thought it was working, but then my eyelids became puffier. Very sad this did not work, because at first my eyes themselves felt so much better. I am 43 and I thought I was relatively healthy - not on any prescriptions, but for some reason I have not had any luck with getting rid of this blepharitis/dry eye issue. I even moved from SW Colorado to Eugene, OR for more moisture! I may try the castor oil again, but would love if someone would post additional remedies - homeopathy, herbs, etc. Also, my blepharitis is just redness, I can't see any scaling, but it does cause red, dry eyes.... doesn't help that I am a computer programmer.
