Believe it or not, but Blepharitis is a Demodex Mites infestation.
Forget about hear this from a MD, they have no clue, about it.
You can use Tree Tea Shampoo.
Never use Tree Tea Oil straight, because it can burn your eyes.Use the shampoo
around your eyes, scrub well on eyelash and eyebrows, wait around 3 minutes and
wash lightly, just to take off the bubbles and leave a little shampoo film on
the area.It´s not a fast cure, it may take around 3 months.During the day and
night you can use coconut oil, as it kills parasites.
Just Google “eyelash mites”
