ACUVUE contacts are made from soft polymers, specifically hydrogel or silicone hydrogel materials, packaged in buffered saline solution. What many wearers don’t realize is that ACUVUE isn’t one lens. ACUVUE is an entire product family, and the material changes depending on which line you’re wearing.
The Two Material Families
ACUVUE lenses fall into two categories, each with distinct trade-offs.
Traditional Hydrogel
Traditional hydrogel lenses are water-based polymers that prioritize softness and initial comfort. They feel plush when you first put them in, which is why they’re often recommended for new wearers or people with sensitive eyes.
The catch is that they rely on water to transport oxygen to your cornea, which limits how breathable they can be.
Silicone Hydrogel
Silicone hydrogel contact lenses take a different approach. By incorporating silicone into the polymer structure, these lenses create channels that allow oxygen to pass directly through, independent of water content. This dramatically increases breathability, sometimes by five or six times compared to traditional hydrogels.
The trade-off is that the material naturally repels water, so these 1 day silicone hydrogel contact lenses require advanced wetting agents to stay comfortable. That’s where ACUVUE’s proprietary technologies like HYDRACLEAR PLUS and LACREON come in.

Discontinued Lenses You Might Still Search For
If you’re looking up old prescriptions or found a box in your drawer, two discontinued lenses still generate searches:
- 1-DAY ACUVUE TruEye used narafilcon A, a silicone hydrogel that was discontinued in the U.S. around 2023
- ACUVUE OASYS with Transitions featured photochromic technology in a senofilcon A lens and was discontinued in 2024
Decoding the Material Names
When you see terms like senofilcon A or etafilcon A on your lens packaging, these are FDA-approved material designations that tell you the specific polymer composition.
Etafilcon A is a copolymer of HEMA (2-hydroxyethyl methacrylate) and MAA (methacrylic acid). It’s classified as a Group IV ionic material, meaning it carries a negative electrical charge that naturally attracts certain proteins from your tears. This can actually be beneficial for biocompatibility.
Senofilcon A and C combine silicone macromers with hydrogel components including DMA, HEMA, and PVP. The difference between A and C is primarily the PVP content. Senofilcon C, used exclusively in ACUVUE VITA, has significantly more PVP embedded throughout the material, which helps it retain moisture over the course of a full month.
The Wetting Technologies That Make the Difference
Here’s something most comparison articles miss: two lenses can use the exact same base material and still feel completely different because of their wetting systems. Material is the foundation, but the wetting technology is what you actually experience on your eye.
LACREON
Found in the 1-DAY ACUVUE MOIST family, this technology permanently embeds a wetting agent into the lens material itself. The agent mimics components of natural tears and doesn’t rinse away with blinking, which is why these lenses maintain their cushioned feel throughout the day.
HYDRACLEAR PLUS
Associated with ACUVUE OASYS 2-Week and some 1-Day variants, this creates a tear-like moisture layer that mimics the mucins in your natural tear film. This helps stabilize the tear film on the lens surface, reducing evaporation rates by up to 50% in some studies.
HydraMax
ACUVUE VITA’s proprietary hydration technology uses high levels of PVP distributed throughout the lens to maintain moisture even as proteins and lipids accumulate over 30 days of wear.
TearStable + OptiBlue
Appearing across the ACUVUE OASYS MAX 1-Day line, TearStable distributes wetting agents more evenly throughout the lens matrix, particularly beneficial for people who blink less frequently during screen time. OptiBlue filters approximately 60% of blue-violet light to reduce digital eye strain.
The Water Content Paradox
One of the most common misconceptions about contact lenses is that higher water content automatically means better hydration and less dryness. The reality is more nuanced.
Traditional hydrogel lenses like 1-DAY ACUVUE MOIST have 58% water content compared to the 38% found in ACUVUE OASYS. On paper, that sounds like the MOIST lenses would be more hydrating. But water content tells you what’s in the lens when you open the package, not what happens after several hours on your eye.
High water content lenses can actually dehydrate faster in certain conditions. If you’re in a low-humidity environment like an air-conditioned office or an airplane, the lens can start pulling moisture from your tear film to replace the water it’s losing to evaporation. This is why some people find that high-water hydrogels feel great initially but become uncomfortable later in the day.
Silicone hydrogel lenses with lower water content but advanced wetting agents often perform better for all-day comfort because they’re designed to resist dehydration.
Material Stiffness: Why Some Lenses Feel Different
If you’ve ever switched from a hydrogel lens to a silicone hydrogel and felt like you could “feel” the new lens more on your eye, you’re not imagining things. This comes down to a property called modulus, which measures how stiff or flexible the material is.
Traditional hydrogels are extremely flexible and conform easily to the eye’s shape. Silicone hydrogels are generally stiffer, which can actually be helpful for handling the lens and maintaining its shape, but some wearers perceive this as the lens being more “present” on the eye.
This is relevant if your lens fit is borderline. A stiffer lens that’s slightly too flat or too steep may cause more awareness or even mechanical irritation as it interacts with your eyelid during blinking.
How Materials Affect Dry Eye and Irritation
Dry eye affects roughly half of all contact lens wearers at some point, and the lens material plays a significant role in either helping or worsening the condition.
Oxygen Deprivation
Oxygen deprivation is one underappreciated cause of contact lens dryness. When your cornea doesn’t get enough oxygen, it can swell slightly and trigger inflammatory responses that disrupt your tear film.
This is where silicone hydrogels like ACUVUE OASYS excel. Clinical studies have shown that overnight corneal swelling with silicone hydrogels averages around 2.7% compared to 8.7% with traditional hydrogels. Less swelling means less inflammation and, often, less dryness.
Deposit Buildup
Deposit buildup matters enormously for comfort. Traditional hydrogels like etafilcon A are ionic, meaning they attract proteins from your tears. Silicone hydrogels are typically non-ionic and more prone to lipid (oil) deposits.
If you have particularly oily tears, you might notice that silicone hydrogel lenses develop a greasy film that makes vision cloudy and causes irritation.
The Daily Disposable Advantage
This is one reason why daily disposable lenses often provide the best comfort for dry eye sufferers. When you throw the lens away at the end of each day, you never give deposits time to accumulate. Studies suggest daily disposables can reduce dry eye flare-ups by 20 to 30% compared to reusable lenses, regardless of the base material.
Protein and Lipid Deposits Explained
Understanding how different materials interact with tear film components helps explain why two people can have completely different experiences with the same lens.
Ionic hydrogel materials like etafilcon A naturally attract proteins such as lysozyme, lactoferrin, and albumin from your tears. These proteins actually form a conditioning film that can improve biocompatibility initially. But over time, this protein layer can denature and become a source of irritation.
Non-ionic silicone hydrogels resist protein buildup better but are magnets for lipids. ACUVUE VITA’s senofilcon C material was specifically engineered to better integrate these lipids into its high-PVP matrix rather than having them sit on the surface as a disruptive film.
The type of contact lens solution you use also matters. Hydrogen peroxide-based solutions are generally better at removing lipid deposits from silicone hydrogels.
Finding Your Material on the Box
Want to know exactly what material your ACUVUE lenses use? Check the side panel of the box or the foil blister label. You’ll see either a material name (like “senofilcon A”) or sometimes a brand name followed by material specs.
Match that material name to the table earlier in this article to understand the oxygen permeability, water content, and technology platform.
Troubleshooting Common Comfort Issues
Dry Eyes That Get Worse Late in the Day
If your lenses feel fine in the morning but progressively drier as the day goes on, the issue is usually evaporation outpacing tear production. Daily disposable lenses often help simply because there’s less time for deposits to interfere with the tear film.
Environmental factors amplify this problem. Air conditioning, heating systems, wind, and low humidity all increase tear evaporation rates. If you work in one of these environments, silicone hydrogels with advanced wetting technologies like TearStable often perform better.
Screen time also contributes. When you stare at a computer or phone, your blink rate can drop from a normal 15-20 blinks per minute down to just 5-7. Fewer blinks means less tear film refreshment. The ACUVUE OASYS MAX 1-Day line specifically targets this issue.
Lenses That Feel Scratchy or Irritating
If a lens feels scratchy or causes redness that develops over the course of the day, it might be a fit issue rather than a material problem. But if you wake up with red, irritated eyes because you’ve been sleeping in your lenses, that’s a behavior issue first.
Extended wear dramatically increases infection risk, even with lenses that are FDA-approved for overnight use.
The “Silicone Allergy” Question
Some wearers claim they’re allergic to silicone hydrogel lenses, but true silicone allergy is biologically implausible. Silicone is one of the most biocompatible materials we have.
What people are usually experiencing is either a reaction to the lens modulus (stiffness), irritation from solution preservatives that have been absorbed into the silicone material, or simply a fit issue. If you’ve had problems with one silicone hydrogel lens, it doesn’t mean you’ll have problems with all of them.
Can You Sleep in ACUVUE Lenses?
Some ACUVUE lenses, particularly ACUVUE OASYS 2-Week, carry FDA approval for extended wear of up to six nights. This is possible because of the high oxygen permeability (147 Dk/t) that allows your cornea to stay healthy even with the lens in place overnight.
However, sleeping in contact lenses, even those approved for it, increases your risk of serious eye infections. The risk increase is substantial, often cited as five to seven times higher than daily wear. Most eye care professionals recommend removing your lenses every night unless there’s a compelling medical reason for extended wear.
UV Protection Across Material Types
One often-overlooked benefit of most ACUVUE materials is built-in UV blocking. Traditional hydrogels like etafilcon A provide Class 2 UV protection, blocking approximately 82% of UVA and 97% of UVB radiation. Silicone hydrogels like senofilcon A and C offer Class 1 protection, blocking more than 96% of UVA and 99% of UVB.
Contact lenses only protect the area they cover, so they don’t replace sunglasses. But the UV blocking in ACUVUE lenses does provide an additional layer of protection for the cornea and lens of your eye.
Choosing the Right Material
Here’s how to match ACUVUE materials to specific needs:
For dry eyes and heavy screen time: ACUVUE OASYS MAX 1-Day with TearStable technology and blue light filtering is specifically designed for this situation. The daily disposable format also eliminates deposit-related dryness.
For astigmatism: ACUVUE OASYS for Astigmatism offers the breathability of senofilcon A with HYDRACLEAR PLUS and Accelerated Stabilization Design to keep the lens properly oriented.
For monthly lens wearers: ACUVUE VITA’s senofilcon C with extra PVP is engineered specifically to combat “end-of-month” discomfort when deposits typically build up.
For sensitive eyes or allergies: 1-DAY ACUVUE MOIST’s etafilcon A with LACREON provides high water content comfort and the benefit of daily disposal, minimizing allergen accumulation.
For contact lens beginners: Starting with a daily disposable in either material family is usually the best approach. It eliminates the complexity of lens care and reduces infection risk.
Frequently Asked Questions
Is ACUVUE OASYS a silicone hydrogel?
Yes. All ACUVUE OASYS variants, whether 2-Week or 1-Day, use senofilcon A, a silicone hydrogel material with 38% water content and up to 147 Dk/t oxygen permeability.
What is senofilcon A?
Senofilcon A is a proprietary silicone hydrogel material that combines silicone macromers with hydrogel components including HEMA, DMA, and PVP. It’s classified as a Group I non-ionic material and is used across the ACUVUE OASYS product family.
What is etafilcon A?
Etafilcon A is a traditional hydrogel material made from HEMA and MAA. It’s a Group IV ionic material with 58% water content and is used in 1-DAY ACUVUE MOIST and ACUVUE 2 lenses.
Which ACUVUE lenses have the highest oxygen permeability?
ACUVUE OASYS 2-Week, ACUVUE OASYS 1-Day (for sphere powers), and ACUVUE VITA all have a Dk/t of 147, which represents the highest oxygen transmission in the ACUVUE family.
Do higher water content lenses fix dry eyes?
Not necessarily. While high water content lenses like 1-DAY ACUVUE MOIST (58%) feel soft and comfortable initially, they can actually dehydrate faster in low-humidity environments. For many people with dry eyes, silicone hydrogels with advanced wetting technologies provide better all-day comfort even though their water content is lower.
Why do my contacts feel dry only at the end of the day?
Late-day dryness usually results from a combination of tear evaporation, deposit buildup, and reduced oxygen reaching the cornea after many hours of wear. Environmental factors like air conditioning and extended screen time exacerbate the problem.
Are 1-DAY ACUVUE TruEye or ACUVUE OASYS with Transitions still available?
No. 1-DAY ACUVUE TruEye was discontinued in the United States around 2023, and ACUVUE OASYS with Transitions was discontinued in 2024. Your eye care provider can recommend current alternatives.
Summary
If you’re experiencing discomfort with your current lenses, the solution might be as simple as switching to a different material within the ACUVUE family or adjusting your wearing schedule. Your eyes deserve materials and technologies that work with your unique tear film, lifestyle, and vision needs.
