Dry Eye, Evaporative

This clinical study involves patients with Dry Eye Disease (DED) who are visiting an ophthalmology outpatient clinic. Eligible participants must have an Ocular Surface Disease Index (OSDI) score ≥14 and \<50, and at least one positive diagnostic test: tear break-up time (TBUT) \<7 seconds, Schirmer I test \<10 mm/5 min, or positive corneal staining based on the Oxford grading scale. At baseline, tear film thickness will be measured using Pentacam imaging. Participants will then receive Proluxx eye spray, applied four times daily for 28 days. After this treatment period, a follow-up examination with all baseline assessments will be repeated.
