Description

Thealoz Duo eye drops combine Trehalose with Sodium Hyaluronate for a dual-action approach to dry eye that goes beyond simple lubrication. Trehalose forms a bioprotective film over corneal cells, mimicking the survival mechanism of desert-adapted organisms that withstand extreme dehydration. HA provides instant moisture.

Widely recommended by Canadian eye care professionals for moderate to severe dryness, this advanced formula provides long-lasting comfort. This reflects its established role in Canadian clinical practice for patients needing consistent, preservative-free lubrication.
Benefits
  • Trehalose bioprotection shields corneal cells from desiccation stress, going beyond standard lubrication
  • Dual-action: HA provides instant moisture while Trehalose delivers lasting cellular protection
  • Preservative-free ABAK bottle stays sterile 2 months after opening
  • Safe for soft and hard contact lenses
  • One of the most recommended dry eye drops by Canadian optometrists
Symptoms

Thealoz Duo eye drops are recommended for people experiencing:

  • Moderate to severe dry eye requiring more than basic lubrication
  • Screen-related dryness from prolonged computer, phone, or device use
  • Meibomian Gland Dysfunction with compromised tear film stability
  • Blepharitis-related surface irritation and tear film breakdown
  • Contact lens dryness during extended wear
Ingredients
  • Trehalose (3%) - Natural sugar found in tardigrades and desert plants that forms a bioprotective film over corneal epithelial cells, shielding them from drying damage rather than just adding temporary moisture
  • Sodium Hyaluronate (0.15%) - Medical-grade hyaluronic acid providing instant lubrication and moisture retention on the eye surface

Preservative-free. Contact lens safe. ABAK bottle, sterile 2 months after opening.
FAQ
Q: How do I use this product?
A: Instill 1 drop in each eye, 4-6 times daily. Safe for contact lenses. ABAK bottle stays sterile 2 months after opening.

Q: What is Trehalose and why does it help?
A: Trehalose is a natural sugar that forms a protective film over corneal cells - like how desert plants survive drought. It actively protects, not just moisturises.

Q: How often can I use preservative-free eye drops?
A: As often as needed - most people find comfort with 2-4 applications daily. No preservatives means no buildup on your cornea.

Q: Can I use these drops with contact lenses?
A: Check the product label. Many preservative-free drops (like Hylo) are safe with contacts. Thicker gels should be used after lens removal.

Q: How is Thealoz Duo different from regular artificial tears?
A: Thealoz Duo contains trehalose, which helps protect and stabilize corneal cells rather than just adding temporary surface moisture. Unlike standard lubricating drops, it is designed to support the ocular surface more actively with regular use.

None of them are working. These eye drops are sensitive to temperature. When I purchased them from a different distributor they did indeed work, repairing my eye and I do not have to put drops in except for every 4 hours. I bought 6 from My pear, trusting that the drops that I would receive would work , however they are not working and I have to put drops in my eyes almost every 10 minutes. Which means the active ingredient has been ruined within the bottles. I have contacted My pear twice with no response back. Asking for a reimbursement or some type of compensation. No response. The drops were discounted and I wonder if it's because they are aware that the drops are not working as effectively.
