Eligibility Criteria
Healthy Volunteers
You may qualify if:
- Volunteer subjects of legal age will be included who agree to participate in the study after being informed by the researcher, receiving the information sheet and signing the informed consent.
- Eye discomfort related to dryness (OSDI score ranged from 13 to 24)
- Symptomatic digital device users (CVSS17 score ranged from 29 to 42 points - stages 3 and 4)
- Use of computer continuously for at least 4 hours per day (work week)
- Good best-corrected visual acuity (Visual acuity LogMar ≤ 0.00 for distance, intermediate (60cm) and near (40cm))
You may not qualify if:
- Systemic administration of drugs with a possible effect on the ocular surface.
- Topical administration of any drugs that can alter the ocular surface.
- Use of contact lenses
