This is a whole essay in this rapidly evolving field.  Dry eyes can occur from deficient tear flow, inadequate mucus in the tears, deficient oils in the tears, inflammation of the lids usually termed meibomian gland dysfunction;  all of which can be worsened by dry atmospheres and dry climates.  There is a 'step ladder' of treatments depending upon the underlying problem which includes lubricating tear replacements, nightly addition of gels and ointments and treatment of the meibomian gland problem if present.  The tear outflow plumbing can be attenuated with temporary or permanent plugs to block outflow.  A variety of mechanical devices can be used to "milk" the lid glands to unclog obstructed output.  Focal heat can be useful.  In more extreme cases, goggles can be used to contain moisture in the eye area and ultrasonic devices can rain a shower of moisture over the bed area during sleep.  Other measures are available for more extreme cases.  You should consult an ophthalmologist if this is a chronic problem - especially a corneal specialist as these commonly deal with these conditions.
