If you wear contacts, there is a good chance your optometrist has mentioned either Acuvue Oasys or Dailies Total 1 at some point. These two lenses sit at the top of the contact lens world, and patients ask me to compare them constantly. Both are silicone hydrogel lenses. Both have excellent oxygen permeability. Both have earned a reputation for comfort. But they are fundamentally different products designed for different priorities.
I have fitted hundreds of patients in both lenses over the years. Here is what I have learned about how they actually compare once they are on a real human eye.
The Head-to-Head Comparison
Before we get into the details, here is the full specs comparison. I am using the Acuvue Oasys biweekly (the most popular version) against Dailies Total 1.
| Factor | Acuvue Oasys (Biweekly) | Dailies Total 1 |
|---|---|---|
| Manufacturer | Johnson & Johnson Vision | Alcon |
| Material | Senofilcon A | Delefilcon A |
| Water content | 38% | 33% (core), >80% (surface) |
| Dk/t (oxygen) | 147 | 156 |
| Replacement schedule | Every 2 weeks | Daily (single use) |
| UV protection | Class 1 (highest) | No |
| Base curve | 8.4, 8.8 | 8.5 |
| Diameter | 14.0 | 14.1 |
| Technology | Hydraclear Plus | Water Gradient |
| Comfort at insertion | Excellent | Excellent |
| End-of-day comfort | Good | Excellent |
| Requires solution? | Yes | No |
The numbers tell part of the story. But there are important details behind each spec that affect how these lenses actually feel on your eyes.
Comfort: Where Dailies Total 1 Pulls Ahead
Both lenses feel great at insertion. The difference shows up at hour 10, 12, or 14 of wear. Acuvue Oasys starts to dry out for some people toward the end of a long day. Dailies Total 1, with its water gradient technology, maintains a cushion of moisture on the lens surface that holds up remarkably well.
The water gradient is the key differentiator. The core of the Dailies Total 1 lens is only 33% water (which keeps it structurally sound and allows high oxygen flow). But the surface transitions to over 80% water content, creating a gel-like layer that mimics natural tears. Your eyelid slides over it rather than dragging across it.
I see this play out consistently in my fittings. Patients who come in complaining that their current biweekly lenses feel dry by 5 pm almost always do better in Dailies Total 1. The improvement in end-of-day comfort is not subtle. It is the single biggest reason people are willing to pay the premium.
Price in Canada: The Elephant in the Room
Comfort is one thing. Cost is another. And the price difference between these two lenses is significant.
| Cost Factor | Acuvue Oasys (Biweekly) | Dailies Total 1 |
|---|---|---|
| Price per box (CAD) | $35-50 (6-pack) | $95-120 (90-pack) |
| Lenses per year | 26 (per eye) | 365 (per eye) |
| Annual lens cost (both eyes) | $250-350 | $700-950 |
| Solution cost per year | $60-100 | $0 |
| Case replacements | $10-15 | $0 |
| Total annual cost | $320-465 | $700-950 |
Even accounting for the solution and case costs that Acuvue Oasys requires, Dailies Total 1 costs roughly twice as much per year. That is a real consideration. Some insurance plans in Canada cover a portion of contact lens costs, but coverage varies widely and rarely covers the full annual expense of premium dailies.
I never push the more expensive option. If someone has healthy eyes, does not suffer from dryness, and is diligent about cleaning their biweekly lenses, Acuvue Oasys is a fantastic lens that costs half as much. Not everyone needs to pay for Dailies Total 1.
Who Each Lens Is Best For
After fitting both lenses for years, I have a clear picture of who thrives in each one.
| Best For | Acuvue Oasys (Biweekly) | Dailies Total 1 |
|---|---|---|
| Budget-conscious wearers | Yes | No |
| Dry eye sufferers | Decent | Excellent |
| Long wear days (12+ hours) | Good | Excellent |
| Part-time wearers (a few days/week) | Wasteful | Perfect |
| Travellers | Need to pack solution | No solution needed |
| People with allergies | Deposits build up | Fresh lens daily, no buildup |
| Kids and teens (compliance concerns) | Requires cleaning discipline | No cleaning, lower infection risk |
| Extended/overnight wear | Approved for up to 6 nights | Not approved |
One scenario where Acuvue Oasys clearly wins: if your lifestyle involves occasional overnight wear. It is approved for up to 6 nights of continuous wear (though I and most optometrists recommend against sleeping in contacts unless absolutely necessary). Dailies Total 1 is a daily disposable and must be removed every night.
The scenario where Dailies Total 1 wins just as clearly: if you only wear contacts 3 or 4 days a week. With biweekly lenses, you open a pair and it expires in 14 days whether you wore it 14 times or 4 times. With dailies, you only use (and pay for) a lens on the days you actually wear them.
Oxygen and Eye Health
Both lenses deliver excellent oxygen to the cornea. Dailies Total 1 has a Dk/t of 156 versus 147 for Acuvue Oasys. In practical terms, this difference is not clinically significant. Both are silicone hydrogel lenses that far exceed the minimum oxygen transmissibility thresholds established by research. Your cornea is well-served by either lens.
Where Acuvue Oasys has a unique advantage is UV protection. It is classified as a Class 1 UV blocker, the highest category, blocking over 99% of UVB and 90% of UVA. Dailies Total 1 does not have UV protection built in. This does not replace sunglasses (the lens only covers your cornea, not your entire eye), but it is an additional layer of protection that some patients value.
The Cleaning Factor
This is where personal habits matter more than lens specifications. Acuvue Oasys is a biweekly lens that requires nightly cleaning with multipurpose solution or hydrogen peroxide. I am going to be blunt: a lot of people do not clean their lenses properly. They rinse and rub for two seconds instead of twenty. They top off old solution instead of replacing it. They wear their biweekly lenses for three or four weeks instead of two.
These habits create real risks. Protein deposits accumulate, bacteria multiply, and the risk of keratitis (corneal infection) increases. Dailies Total 1 eliminates this variable entirely. You open a fresh, sterile lens in the morning and throw it away at night. There is no case to contaminate, no solution to forget, no temptation to stretch the wearing schedule.
For patients who I know are not going to follow a cleaning routine perfectly, I lean toward recommending dailies. The reduced infection risk is worth the added cost.
My Bottom Line
If comfort is your top priority and budget is secondary, Dailies Total 1 is the better lens. Full stop. The water gradient technology delivers noticeably better end-of-day comfort, and the daily disposable format removes the compliance risks that come with reusable lenses.
If you want an excellent contact lens at a reasonable price and you are committed to proper cleaning habits, Acuvue Oasys is a proven performer that has earned its place as one of the most prescribed lenses in Canada for good reason. It is not a compromise. It is a genuinely good lens that costs half as much.
The best lens is the one that fits your eye, your lifestyle, and your budget. Your optometrist can help you make that call with a trial fitting. Most clinics will let you try both before committing to a full supply.
Frequently Asked Questions
Which is better, Acuvue Oasys or Dailies Total 1?
Neither is universally "better." They excel in different areas. Dailies Total 1 offers superior end-of-day comfort thanks to its water gradient surface and eliminates cleaning hassles as a daily disposable. Acuvue Oasys biweekly costs about half as much per year and performs well for most healthy eyes. For dry eye sufferers, allergy patients, and part-time wearers, Dailies Total 1 generally pulls ahead. For budget-conscious full-time wearers with good compliance habits, Acuvue Oasys is hard to beat.
How much do Dailies Total 1 cost in Canada?
A 90-pack of Dailies Total 1 costs between $95 and $120 CAD at most Canadian optical retailers. For a full year of daily wear (both eyes), expect to spend $700 to $950 CAD depending on your prescription, any rebates, and where you buy. Acuvue Oasys biweekly runs approximately $250 to $350 CAD per year plus $60 to $100 for solution. Some employer insurance plans cover a portion of contact lens costs, so check your benefits.
Can I switch from Acuvue Oasys to Dailies Total 1 without a new fitting?
You should not. Even though both are soft contact lenses, they have different base curves, diameters, and materials. A lens that fits well in one brand may not sit properly in another. Your optometrist or optician needs to evaluate the new lens on your eye and update your prescription accordingly. In Canada, contact lens prescriptions are brand-specific, so you need a new prescription to switch.
Are Dailies Total 1 good for dry eyes?
Yes, they are one of the top choices for dry eye contact lens wearers. The water gradient technology creates an outer surface that is over 80% water, which reduces friction between the lens and eyelid. Because they are daily disposables, there is no protein or lipid deposit buildup that can worsen dryness over a wearing cycle. Many optometrists consider Dailies Total 1 the gold standard daily lens for patients with mild to moderate dry eye.
Can you sleep in Acuvue Oasys lenses?
Acuvue Oasys is approved for up to 6 nights of extended (overnight) wear. However, sleeping in any contact lens increases your risk of corneal infection by 6 to 8 times compared to removing them nightly. The Canadian Association of Optometrists and most eye care professionals recommend against sleeping in contacts unless there is a specific medical reason. Dailies Total 1 is a daily disposable and should never be slept in.
Which lens has higher oxygen permeability?
Dailies Total 1 has a Dk/t of 156 versus 147 for Acuvue Oasys. Both numbers are well above the minimum thresholds for healthy corneal function. The practical difference between them is minimal. Both lenses deliver excellent oxygen to the cornea, and neither will cause oxygen-related problems during normal daily wear.
Is Acuvue Oasys 1-Day the same as Acuvue Oasys biweekly?
No, they are different lenses. Acuvue Oasys 1-Day with HydraLuxe is a daily disposable with a thinner design optimized for single-day use. Acuvue Oasys (biweekly) with Hydraclear Plus is designed for 14-day wear cycles with nightly cleaning. They use different lens designs, different wetting technologies, and are not interchangeable. If you are comparing to Dailies Total 1, make sure you are comparing the right Oasys product.
