I used to have this problem too. Tried prescriptions, systane, hydration eye drops etc etc, but in the end but actually worked was baby shampoo rinsing my eyes twice a day and washing them it took some time but now it's completely gone. But for me I believe it was some sort of blepharitis that was blocking the glands that produced the lubrication my eyes needed, and now that I have a good routine, it appears to have solve the problem.
