Updated September 2026 · Reviewed against published ophthalmology sources
A bandage contact lens is a soft lens worn to protect a healing cornea, not to correct your vision.
One goes on the eye after an injury, an infection, or surgery, on your eye doctor’s call. It shields the raw surface from your own blinking eyelid, which is a big part of why a small scratch can hurt so much, and it gives the tissue underneath a calm environment to close up in.
These are prescription medical devices, and your eye doctor directs how yours is used. This page explains what they are and what to expect. It does not tell you how to handle one, because those instructions should come from the doctor treating your eye.
If your doctor just put one in, or mentioned you might need one, you probably have a short list of questions. What is it actually doing in there. How long does it stay. Is it supposed to feel like this. Here are the answers, drawn from published ophthalmology sources rather than guesswork.

What a bandage contact lens actually does
The cornea, the clear dome at the front of your eye, is one of the most densely nerved surfaces in the human body. That is why a scratch the size of a pinhead can feel catastrophic, and why every blink after an injury feels like sandpaper.
A bandage lens, sometimes called a therapeutic lens, sits over that surface and does three things at once.
✓ It stops the pain at the source. The lens covers exposed nerve endings so your eyelid glides over smooth plastic instead of dragging across the injury.
✓ It acts as a physical shield. Blinking, dust, and air currents all irritate a healing surface. The lens takes that contact instead.
✓ It holds moisture against the cornea. A stable, damp surface is what new cells need in order to migrate across the gap and close it.
Note what is missing from that list: vision correction. A bandage lens is usually plano, meaning zero power, with no prescription strength ground into it. It is a dressing that happens to be shaped like a contact lens. Moorfields Eye Hospital describes it simply as “a therapeutic contact lens (usually soft) which you wear in your eye for an extended period of time.”
What doctors use them for
Bandage lenses show up across a wide range of situations, and most of them fall into one of three buckets.
Injuries to the surface of the eye. Corneal abrasions, which are scratches from a fingernail, a tree branch, or a stray contact lens, are among the most common reasons. So is recurrent corneal erosion, where a previously healed scratch keeps reopening.
Recovery after eye surgery. Procedures such as PRK and corneal crosslinking leave the surface layer disturbed on purpose, and a bandage lens covers it while it regrows. Some cataract and glaucoma procedures call for one as well.
Chronic surface disease. Severe dry eye, corneal ulcers, neurotrophic keratitis, and certain eyelid conditions that cause constant rubbing can all be managed in part with a therapeutic lens.
In every one of these, the lens is a supporting player. It is buying comfort and protection while the real healing happens underneath, usually alongside prescribed drops.
How long does a bandage contact lens stay in?
That depends entirely on what it is treating, and the answer comes from your doctor rather than from a general rule online.
For context, a lens placed after PRK is commonly removed at around a week, once the surface has closed. A simple abrasion may need only a few days. Chronic conditions can call for several weeks of continuous wear, replaced on a schedule your doctor sets.
Who handles the lens
For short-term use, your eye doctor normally does the placing and removing. Moorfields Eye Hospital tells patients “you will not normally be expected to handle the contact lens yourself,” and describes seeing an optometrist at regular intervals to have the lens removed and replaced.
Long-term wear is different. Moorfields goes on to say that “if you need the lens for long-term treatment, then we may give you instructions on how to insert and remove the lens yourself,” with one condition attached: “you must only do this when you have received the appropriate training and you have been told it is safe to do so independently.” That is the line that matters. Handle your own lens only if your doctor has trained you and cleared you to, and follow the instructions they gave you rather than anything you read online.
Bandage lenses are also worn overnight, which is the opposite of what you may have been told about ordinary contacts. That is intentional and it is supervised. It is not permission to sleep in your regular lenses.
Are bandage contact lenses safe?
Under a doctor’s supervision, the evidence says yes, and there is a solid study behind that.
A 2024 analysis published in BMC Ophthalmology reviewed ten years of records at a German tertiary eye hospital, covering 638 consecutive patients who were prescribed bandage contact lenses. The researchers went looking specifically for serious, sight-threatening complications.
Bandage contact lenses are safe given proper ophthalmological supervision.
Conclusion of the 2024 BMC Ophthalmology review of 638 patients
The detail worth understanding is why. Serious events did occur in that population, but the authors found that severe outcomes were almost never caused by the lenses themselves. These were patients who already had significant eye disease, which is why they needed a bandage lens in the first place. Of the endophthalmitis cases identified across a decade, only two could be linked to bandage lens wear at all.
The authors singled out one protective factor in that group: the lenses were not handled by the patients themselves. Fewer hands on the lens means fewer chances to introduce the bacteria behind most contact lens infections. It is a useful finding even if your own situation is different, because it explains why hygiene and follow-up visits carry so much weight with a lens worn continuously.
Blurry vision and mild discomfort
Two things people frequently search for after getting one, so they are worth naming.
Blurry vision is common and usually expected. A bandage lens has no corrective power, the eye underneath it is injured and swollen, and you may be using ointments or drops that fog things further. Blur that is stable or gradually improving is generally part of the process. Blur that suddenly worsens is not, and that one gets a phone call.
Some awareness of the lens is normal. Real pain is not. Most people describe a sense that something is there, which fades over the first day or so as the eye settles. Increasing pain, rather than decreasing pain, is a signal that something has changed.
When to call your eye doctor
Moorfields advises patients wearing a bandage lens to seek attention promptly for any of the following. This list is short on purpose. If you notice any of it, contact your eye doctor or an eye casualty service straight away.
⚠ Increasing redness
⚠ Discharge from the eye
⚠ Pain, particularly pain that is getting worse
⚠ Decreased vision
One practical tip from the same guidance: if you end up seeing any clinician for any reason while a bandage lens is in, tell them it is there. It is not always obvious on examination, and they need to know.
Can you buy bandage contact lenses over the counter?
No. Every contact lens sold in the United States is a regulated medical device requiring a valid prescription, and that includes lenses with no corrective power in them. A bandage lens is plano, but it is still prescription only, and any seller who does not ask for prescription details is not operating legally.
What you can do, once your eye doctor has prescribed them, is buy your refills wherever you like. You are not required to buy from the practice that treated you. Your prescription is yours, and a legitimate retailer will verify it with your doctor before shipping.
Ordering a refill: two details that trip people up
The power is 0.00. Because a bandage lens does not correct vision, you select 0.00 power for both eyes when you order. People often assume this is a mistake in the form. It is not.
The base curve comes from your doctor. Fit matters more here than with an ordinary lens, and your prescription will specify which base curve you were fitted in. If you are unsure how to read that, our guide to reading your contact lens prescription covers every line on the page.
The most widely prescribed option is the Acuvue Oasys Bandage Lens from Johnson & Johnson. It is a senofilcon A silicone hydrogel, which is the material class doctors reach for in therapeutic use because it moves a great deal of oxygen to a cornea that is already under stress. It carries HYDRACLEAR Plus for moisture retention and Class 1 UV blocking, and it comes in 8.4 and 8.8 base curves at a 14.0 mm diameter. Your doctor will tell you which curve you were fitted in.
You can send us your prescription before, during, or after checkout.
The bottom line
A bandage contact lens is a dressing for your eye. It takes the pain out of blinking, protects a surface that cannot protect itself, and holds the right conditions for healing. It does not correct your vision and it is not something you manage on your own.
Handled the way it is meant to be handled, with your eye doctor setting the schedule and doing the placement, the published evidence is reassuring. Follow their plan, watch for the four warning signs above, and call them rather than guessing.
Frequently asked questions
What is a bandage contact lens?
A bandage contact lens, also called a therapeutic contact lens, is a soft lens placed on the eye to protect a healing cornea and relieve pain. It covers exposed nerve endings so blinking does not drag across the injury, shields the surface from dust and air, and holds moisture against the eye. It has no corrective power and is prescribed and managed by an eye doctor.
Can you buy bandage contact lenses over the counter?
No. All contact lenses sold in the United States are regulated medical devices that require a valid prescription, including bandage lenses with no corrective power. Once your eye doctor has prescribed them, you can buy refills from any seller you choose, and a legitimate retailer will verify the prescription with your doctor before shipping.
How long can you wear a bandage contact lens?
Your eye doctor decides, based on what is being treated. For context, a lens placed after PRK surgery is commonly removed at about a week, a simple corneal abrasion may need only a few days, and chronic surface conditions can call for several weeks of continuous wear. Unlike ordinary contacts, bandage lenses are worn overnight, which is intentional and supervised.
Are bandage contact lenses safe?
Under proper supervision, yes. A 2024 study in BMC Ophthalmology reviewed 638 patients prescribed bandage lenses over ten years and concluded that they are safe given proper ophthalmological supervision, finding that severe adverse events were almost never caused by the lenses themselves. The authors highlighted that patients did not handle the lenses, which removes the main route of contamination.
Do bandage contact lenses help a corneal abrasion?
Corneal abrasions are one of the most common reasons a bandage lens is used. The lens stops the eyelid from dragging over the scratch with every blink, which is a big part of why an abrasion hurts, and keeps the surface protected while new cells migrate across. Whether one is appropriate for a particular abrasion is a decision for your eye doctor.
Why is my vision blurry with a bandage contact lens?
Some blur is expected. The lens has no corrective power, the eye underneath is injured and often swollen, and any ointments or drops you are using add to it. Blur that is steady or slowly improving is usually part of healing. Vision that suddenly gets worse is a reason to contact your eye doctor right away.
What are the side effects of a bandage contact lens?
Reported risks include eye irritation and allergic response, inflammation, and infection, with corneal ulcers and other serious infections being the main concern with any lens worn continuously. Contact your eye doctor promptly if you notice increasing redness, discharge, pain, or decreased vision.
Can I take out a bandage contact lens myself?
Only if your eye doctor has trained you and told you it is safe to do so. For short-term use, patients are not normally expected to handle the lens, and an optometrist removes and replaces it at scheduled visits. For long-term treatment, Moorfields Eye Hospital notes that patients may be given instructions to insert and remove the lens themselves, but only after appropriate training. If nobody has trained you, or the lens comes out on its own, call your eye doctor rather than improvising.
What power do I select when ordering bandage lenses?
Bandage lenses are plano, meaning 0.00 power, so you select 0.00 for both eyes. The base curve is the number that matters, and it comes from your prescription, since your doctor fitted you in a specific curve. Acuvue Oasys Bandage Lenses are offered in 8.4 and 8.8 base curves at a 14.0 mm diameter.
