# Preservative-free dry eye drops

Compare lubricating drops, contact-lens suitability and expiry after opening.

**What you need to know**

Lubricating drops are used for dry-eye symptoms. Preservative-free does not mean every drop is suitable for every contact lens or every eye condition. Check the finished product instructions, storage requirements and how soon an opened bottle must be discarded.

This is an educational guide. Sanara is not taking orders or preorders. Compare the actual product’s label, suitability and total cost before buying from a retailer.

What to check before buying

## Check the label

- Lubricating ingredient and concentration
- Contact-lens compatibility
- Discard-after-opening period

## Directions and pack size

Use only as directed on the finished product’s label or patient information leaflet. Sanara has not verified a specific pack, dose schedule or supply duration for this guide.

## Safety

For external ocular use only. Stop use and seek advice if irritation persists. If you have eye pain or sudden vision changes, seek medical advice.
