Thealoz® Duo Eye Drops

These premium quality, professional grade artificial tears are recommended by our Optometrists to help treat both aqeous deficient and lipid deficient dry eye.  They also have natural anti-inflammatory properties which help reduce itchiness and burning without the side effects of traditional anti-inflammatory pharmaceutical such as steroids which may cause unwanted side effects.

Thealoz Duo Artificial tears contain trehalose 3% and sodium hyaluronate 0.15% in a preservative-free formulation
Trehalose protects the epithelial cells on the ocular surface, improving their resistance to daily stress of dry environments and tear film changes in a dry eye; it has very high water retention capabilities with both bioprotection and osmoprotection properties.

Sodium hyaluronate adds moisture by retaining water to hydrate and lubricate the surface of the eye – this allows for longer lasting moisturizing effect and less frequent dosing needs to keep your eyes feeling dry and comfortable and your vision clear.

Thealoz Duo Eye Drops are indicated for moderate to severe dry eye disease. Clinical studies have shown that a single drop of Thealoz Duo improves the thickness of the tear film for at least 4 hours (6 times longer than sodium hyaluronate alone).8 In one study, 62% of patients receiving Thealoz Duo were symptom free after 84 days, with significant improvements in blurred vision, stinging and itching.

Thealoz Duo is a hypotonic formulation (low osmolarity), which means it particularly addresses the hyperosmolarity of the tear film in chronic dry eye to effectively soothe symptoms.

The uniquely designed, patented, preservative-free bottle allows easy application.

Products containing preservatives can cause ocular surface toxicity, leading to inflammation and cell death. Using preservative-free eye drops supports the health of the ocular surface


Preservative-free relief from dry eye symptoms. Thealoz® Duo contains two proven dry eye therapies in one bottle:

  1. Trehalose: a natural substance present in many plants and animals that survive in extremely dry conditions. It helps protect the eye from dryness.
  2. Hyaluronic acid: a gentle solution that lubricates with long-lasting relief

These eye drops are excellent. I use them several times a day for dry eyes and keep them with me at all times. They feel so good in my eyes!!!!

Dave Canty

This products contain sodium hyaluronate. Keep your eyes moist. Nothing eliminates my dry eyes completely but this is the best product I have found to contain it. I have tried every drugstore product. This works for me.

Sam Gaines

These eye drops are amazing. They have helped me through a very serious attack of chronic dry eye disease, and I will be using these from now.

Eddie Wolff

I purchased Thealoz Duo Dry Eye Drops recently. Brilliant specially if you were contact lens as you can add the drops even when you have your lens in.

Lynda Robitaille

I love these eyedrops! I was so happy to find an online shop that would ship it to my home. I am extremely impressed with the one-day shipping that I received. Thank you very much!
