Well, in my opinion, fish oil can be good for it. As we know that Blephariti is inflammation and it occurs on the part of the eyelid where the eyelashes grow. Because of it, your eyes can eventually become red, irritated and itchy. And when the small oil glands near the base of the eyelashes don't work properly, it can be possible too. And according to some experts, supplementation with fish oil could be a very cost-effective way to help reduce inflammation caused by blepharitis. So you can just have more herring and salmon. Anyway, just have a try.
Yes, as far as I know, fish oil can help blepharitis. Taking fish oil can be helpful for reducing itchiness, burning caused by blepharitis. Fish oil provides a good source for omega-3 fatty acids, which is good for the blepharitis. What's more, some fats like flaxseed oil can also be helpful.
