Key Points
- Preservative note: Refresh Tears contains Purite (a preservative). Because of this, use should be limited to no more than 4 times per day. If you need drops more frequently than that, a preservative-free formulation (like Refresh Plus single-use vials) is the better choice to avoid preservative-related irritation.
- Use as needed: There is no fixed minimum dose - use only when symptoms require it.
- Duration: If irritation, eye pain, or vision changes persist beyond 72 hours or worsen, stop use and consult a doctor.
- No maximum daily drop count is specified in the official labeling beyond the preservative-frequency guidance above.
When to See a Doctor
Stop using and seek care if you experience:
- Eye pain
- Vision changes
- Worsening or persisting symptoms beyond 72 hours
