Full-spectrum LED screen-bar lighting as an adjunct to artificial tears in visual display terminal-related dry eye: a randomized study

To evaluate the short-term clinical effect of adding a full-spectrum screen-bar lamp as an environmental adjunct to artificial tear therapy in participants with newly diagnosed visual display terminal (VDT)-related dry eye.

In this prospective, randomised, single-center study, 66 participants with newly diagnosed VDT-related dry eye and limited corneal staining were assigned to a full-spectrum screen-bar lamp plus artificial tears (intervention group, n = 34) or artificial tears alone with no study lamp (control group, n = 32). Primary endpoints were changes in Ocular Surface Disease Index (OSDI) and non-invasive tear breakup time (NIBUT) from baseline to one month.
