For those of you whose eyes are too sensitive to agree with anything (eg. castor oil), I highly recommend using coconut oil and coconut milk internally. I had very bad dry eyes for 3 nights, could not open my eyes when I woke up and stressing about the long term pain made it even worse. Also trying everything from OTC to natural remedies in my eyes all made them worse. I decided to eat coconut oil and drink coconut milk and eat a lot really healthy food, have faith in my body's natural healing and plenty of sleep for 2 days and my eyes have gone back to pretty much normal. Your body has a natural healing power with the right fuel and you need to have faith in it, too.
Good luck!
