TearStable is a moisture-maintaining technology in contact lenses developed by Johnson & Johnson Vision Care and first released in September 2022. TearStable supports the stability of the tear film as it reduces the tear evaporation rate significantly when compared to other contact lens technologies. Tear stability is a major factor in contact lens wearing comfort and crucial for wearing contact lenses all-day. Johnson & Johnson Vision Care's TearStable technology is based on a proprietary pvp-based (polyvinylpyrrolidone) wetting agent that gets evenly applied to the contact lens surface of all ACUVUE OASYS MAX 1-DAY products.
Let's further dive into TearStable Technology and how it can enhance your eye comfort.
What is TearStable Technology?
Exclusively available with the daily-replaceable ACUVUE OASYS MAX 1-DAY product family, TearStable Technology is an innovative approach in contact lens design that supports the natural tear film of your eyes. This specialized technology replicates the lubricating and moisturizing properties of your tears, ensuring a comfortable and healthy eye experience.
Moisture Retention with TearStable Technology
TearStable Technology employs an advanced manufacturing process, utilizing Senofilcon A (a proven silicone hydrogel material) and optimizing the distribution of a wetting agent across the contact lens surface. This wetting agent, known as high-molecular-weight polyvinylpyrrolidone (PVP), behaves much like the natural eye component mucin. PVP possesses both hydrophilic and lipophilic properties, allowing it to attract and evenly spread both water and lipid components of your tear film. This results in superior moisture retention and lubrication, keeping your eyes refreshed throughout the day.
Biocompatibility and Clear Vision
Another key element of TearStable Technology is the combination of PVP with a self-hydrating silicone monomer (SiMMA) known from other ACUVUE OASYS products. This unique blend interacts with water and PVP to create a lens material that's not only comfortable but also biocompatible, ensuring a comfortable and clear vision experience.
Reduced Tear Evaporation for Comfort
One of the challenges with contact lenses is tear evaporation, which can lead to discomfort. TearStable Technology addresses this issue effectively. Studies have shown that contact lenses using TearStable Technology, like ACUVUE OASYS MAX 1-DAY lenses, can reduce tear evaporation by nearly half compared to other lenses. This means less irritation and more comfort for your eyes.
Enhanced Tear Film Stability for Clear Vision
A stable tear film is essential for maintaining clear vision. With TearStable Technology, wearers of ACUVUE OASYS MAX 1-DAY lenses experience a stable tear film that is 1.6 times more likely to last longer. This improved tear film stability translates to superior optical quality and clear vision throughout the day.

In summary, TearStable Technology offers numerous benefits, including increased comfort, reduced tear evaporation, and enhanced tear film stability for clear and comfortable vision.
