Here is something I recently learned that everyone should take note of if you have eye problems from the bacteria or blepharitis type issues. For 10 years I was going to eye doctor and when they said do lid scrubs I washed in the shower in the morning, but never really took it seriously with the eye lids other then that, and of course I continued to have dry eyes and itchy eyes from this. Finally I read elsewhere that people with the exact same symptoms as me said I needed to do it 2 or 3 times every day.
Anyways for the past month, I started taking it much more serious. Every morning I use baby shampoo and rub little circles all way up and down my eye lashes (I can feel the top eye lashes pushing up when I do this). You dont have to do it hard, dont rough it up, just clean it like this. It probably takes me 30 seconds of doing these along the eye line. Then I also soap and wash my face to get rid of all oil including the eyebrows (think that you need to get rid of oil everywhere there). I've done this every day morning, sometimes mid day, and always before bed. This means twice a day every day, sometimes 3 times.
The opthamologist just told me its the best he has ever seen the blepharitis on me. It works. He said on a scale of 1 to 10, its under a 2, this is the first time in years the doctor has said anything positive related to this to me. The bottom line is you just have to take it serious.
