Eye drynss syndrome is a very common but annoying problem, referring to deficient tear production or excessive tear evaporation or drainage. Tear works as lubrication, nourishment and anti-bacterial agent in eyes. Without enough anti-bacterial agent in eyes, it makes easier to get bacterial infection. So it is possible to have pink eye because of long term eye dryness. And severe dryness might lead to inflammation, scarring on the surface of cornea for lacking of lubracation. To prevent it, you should reduce the dryness. Applying warm compress is helpful to tear production. You can do the warm compress 4-6times per day, 10-15 minutes each time. Make sure the air around is moist enough otherwise your eyes would be drier. Use a humidifier to moisturize the air, which make you feel better and the dryness would be relieved.
