Buy Thealoz Duo Anti-Evaporation Drops for moderate to severe dry eye. The dual ingredients also work beautifully well for computer-related dry eye.
ā Best For:
- Computer users 40+ with screen-related dry eye
- Moderate to severe dry eye from poor lid oil production
- Evaporative dry eye (tears dry too quickly)
- Blepharitis patients using warm compresses
Summary: Ā Thealoz Duo Lubricating Eye Drops are preservative-free artificial tears designed to relieve moderate to severe dry eye, particularly evaporative dry eye associated with meibomian gland dysfunction, blepharitis, or prolonged screen use. The formula combines 3% trehalose, which helps protect ocular surface cells from dryness and evaporation, with 0.15% sodium hyaluronate, a lubricant that supports tear film stability and hydration. Together these ingredients help reduce irritation, dryness, and digital eye strain while improving tear film protection. Thealoz Duo is preservative-free, phosphate-free, and compatible with contact lenses, and uses a multidose bottle system that maintains sterility for up to 6 months after opening.
Description:
If you have been recommended warm compresses for dry eye treatment, buy Thealoz DUO anti-evaporative drops as good concurrent treatment.
Why Thealoz Duo Works Better
Two synergistic ingredients in one bottle:
- Trehalose (3%): A natural anti-evaporative substance present in nature that helps many plants and animals survive extremely dry conditions. Use before your work-day and at lunch to pro-actively protect the sensitive cornea from drying out.
- Sodium Hyaluronate (0.15%): Lubricates with long-lasting relief and is the active ingredient in Hyabak
Clinically proven: Buy Thealoz DUO as it is the only artificial tear proven to reduce inflammatory markers (IL-1b/6/8) with 60 day use! (2023 Study Reference: anti-inflammatory study)

How to Use Thealoz Duo
Pro-active approach works best: Use the drop before your work-day and perhaps at lunch to pro-actively protect the sensitive cornea from drying out. The Trehalose ingredient limits evaporation, so timing matters.
Each bottle contains ~300 drops. In-clinic, I typically recommend 2x/day so that is over ~4 months of relief.
ā ļø Important to Know
There are no silver bullets - this (nor any) drop is not the answer for all forms of dry eye for all people. Please see more information: Dry Eye blogs, Digital Eye Strain Blogs, Blepharitis Blogs and speak to your eye care professional about the correct dry eye therapy for you.
Dr Morris' comments: We recommend anti-evaporative eye drops for those who have poor lid oil production or high screen-time demands. See this blog entry on digital screen dry eye.
Frequently Asked Questions
How is Thealoz Duo different from regular eye drops?
Thealoz Duo combines two active ingredients (Trehalose + Sodium Hyaluronate) specifically designed to prevent tear evaporation. Regular lubricating drops only add moisture - Thealoz Duo keeps that moisture from evaporating, making it ideal for computer users and evaporative dry eye.
Can I use Thealoz Duo with contact lenses?
Yes! Thealoz Duo is safe to use while wearing contact lenses. The preservative-free formula is gentle enough for frequent use throughout the day.
How long does a bottle last once opened?
The special Thea bottle has a 180-day shelf life once opened - 6 times longer than standard bottles. Each bottle contains ~300 drops, which lasts over 4 months with typical 2x/day use.
When should I use Thealoz Duo during the day?
For best results, use before your work-day starts and again at lunch. The anti-evaporative ingredients work pro-actively, so applying before screen time is more effective than waiting until your eyes feel dry.
Is Thealoz Duo preservative-free?
Yes, completely preservative-free and phosphate-free. The special filtered Thea bottle allows for non-preserved drops that are very gentle to the ocular surface and can be used many times a day if required.
Who should use Thealoz Duo?
Thealoz Duo is best for moderate to severe dry eye, especially if you have poor lid oil production, high screen time (computer users 40+), evaporative dry eye, or have been recommended warm compresses for blepharitis.
