Very good for dry eye. Better than a dry eye vitamin.
I can't comment on pain relief. I originally started taking it for a blood clot. I was already taking Maxi Tears for dry eyes vitamins, Restasis BID and plugs in my eyes every 3mos.  I stopped taking Maxi Tears when I started this fish oil.  Didn't need the Maxi Tears anymore.  I tried another fish oil, dry eye was our of control.  My doctor looked at the EPA of 800 and DHA of 500.  These are higher than even a vitamin like Maxi Tears for dry eyes. I immediately switched back to Norwegian and my dry eye has been under control overall since.  I get the lemon flavor and put it in my daily Special Detox drink with apple cider vinegar, etc. It is what I use in place of lemon juice or real lemon in my drink and a way to digest it daily.  Or you can put it on a salad or rice.  It has a nice flavor without the fishy smell.  When I tried to take it only by itself, it gave me heartburn. Highly recommend this product, as it also helped my blood clot but especially has been helping my dry eye.<br />I don't see Sunflower oil as an ingredient for those concerned, however if it is there, in the Q & A it is explained that it is a very small amount.  I also don't notice a change in taste and have been taking it for at least a few years now.  I also read it helps migraines, so I am going to share with a friend.
