Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age 18-70 years (inclusive), male or female; 2. Subject reports dry eye symptoms for at least 6 months; 3. Diagnosis of mild to moderate dry eye according to the Chinese Dry Eye Expert Consensus (2020) criteria: * Mild dry eye: fluorescein tear film break-up time (FBUT) ≥2 seconds, no significant ocular surface damage signs, corneal fluorescein staining score \<5; * Moderate dry eye: FBUT ≥2 seconds AND corneal fluorescein staining dots \<30 or not exceeding 2 quadrants; 4. Normal tear secretion: Schirmer I test ≥10 mm/5 min; 5. Daily electronic screen usage \>6 hours; 6. Electronic screen use for at least 5 days/week, for more than 1 year; 7. Understands and provides written informed consent. Exclusion Criteria: 1. Allergy or hypersensitivity to any component of the study drugs; 2. Requires the use of artificial tears (other than study drug), secretagogues, ocular surface repair agents, anti-inflammatory/antibiotic eye drops, or other dry eye-related drugs (e.g., muscarinic receptor blockers for visual fatigue) during the study period; 3. Presence of any of the following ocular or systemic conditions: * Active ocular infection, ocular inflammation, or active ocular allergy; * Conjunctivochalasis, nasolacrimal duct obstruction; * Glaucoma or elevated intraocular pressure; * Retinal disease or ocular tumor; * Requirement to wear contact lenses during the study; * Obstructive sleep apnea syndrome or sleep disorders; * Planned or ongoing physical therapy (intense pulsed light, meibomian gland massage, warm compress, thermopulsation) within 2 weeks before enrollment through the end of study; 4. Ocular surgery within 3 months prior to enrollment, incomplete recovery from previous ocular surgery, or planned ophthalmic surgery during the study period; 5. Current smoker; 6. Pregnant or breastfeeding women, or women planning to become pregnant during the study period; 7. Uncontrolled systemic disease, or use of systemic medications (e.g., beta-blockers, benzodiazepines, corticosteroids, antihistamines, or other medications that may interfere with tear production); 8. History of anxiety or depression; 9. Any other condition that, in the judgment of the investigator, would make the subject unsuitable for participation.
