This is a possible answer for Loose Rivets, when I went for my class 1 medical a while back I was given some great information about dry eyes. For many years I have had constant dry eye problems, in the morning I would wake up and take ages for my eyes to focus, in addition during the day I was having to use eys drops to lubricant the eyes
The eye doctor at the CAA performed a miracle, she said that my eyes were producing to much 'healthly bacteria' which was making my eyes clog up'
I was told to was my eyes daily (with eyes closed) with Johnsons baby shampoo. 3 months later, my eyes are cristal clear, no eye drops and no dry eyes. It worked for me, but speak to your own doctor or even the CAA before trying it, as I suspect people will be different.
Good luck
