The purpose of this research was to determine the effect of two artificial tears of different viscosities in the relief of environmental dry eye induced with a novel tear stress test (TST). A novel TST was developed and validated. The following four test conditions were evaluated in 12 healthy normal subjects in a cross-over and subject masked study; unprotected (no test solution used), relief (test solution instilled just after application of TST), immediate protection (test solution instilled just before application of TST), and chronic protection (1 week prophylactic use of the solution).
