What's the best treatment available for blepharitis ?

I am not an expert: But conservative treatment first. Possibly antiinflammatory or steroids? Ask your eye doc. Make sure no fever or eye pain or vision loss.

Eyelid hygiene: The best treatment is to clean your eyelids and lashes with baby shampoo and place a warm compress over your eyelids x 10 minutes twice a day. You should incorporate this into your daily hygiene routine. You can also take a nutritional supplement such as omega three fatty acids or flaxseed oil to improve the oily layer of your tear film.
