It’s a specific kind of terror. You go to rub your eye or take your lens out at the end of a long day, and suddenly, it’s just... gone. You blink. You look in the mirror. You poke around. Nothing. The immediate thought most people have is that the lens has somehow slipped into the dark abyss behind their eyeball and is currently migrating toward their brain.
I have good news: that is anatomically impossible.
The human eye has a built-in safety net called the conjunctiva. This thin, moist lining covers the white part of your eye and folds back to line the inside of your eyelids. It creates a sealed pouch. There is literally no physical path for a contact lens to travel to the back of your head. If you’re trying to figure out how to get a contact out from behind your eye, you aren't looking for something lost in a cave; you’re looking for a lens that is simply tucked under a flap of skin.
It’s stuck. It’s annoying. It might even sting. But it’s still on the front surface of your eye.

Why Lenses Decide to Hide
Usually, this happens because your eyes are too dry. When the cornea lacks moisture, the lens loses its grip and starts to slide. Maybe you fell asleep in them (we’ve all done it), or maybe you’ve been staring at a computer screen for eight hours without blinking. Sometimes, vigorous eye-rubbing is the culprit.
Soft lenses are the usual suspects here because they are incredibly pliable. They can fold in half like a tiny taco and wedge themselves deep into the upper fornix—that's the medical term for the pocket under your upper eyelid. According to the American Academy of Ophthalmology (AAO), the most common reason for a "lost" lens is simply displacement into this pocket.
The Step-by-Step Retrieval Method
First, breathe. Seriously. If you're tensed up, your eyelids will clamp down harder, making it way more difficult to get the lens out.
Wash your hands. This is non-negotiable. Use plain soap and dry them with a lint-free towel. You don't want to add a bacterial infection to your current list of problems.
Now, find a well-lit mirror. You need to identify where the lens actually is. Most of the time, it’s tucked under the upper lid. Look as far down as you can toward your chest while pulling your upper eyelid upward. If you see a glimpse of the edge of the lens, you’re halfway there.

The Rewetting Trick
Don't try to grab a dry lens. If the lens is dehydrated, it will stick to your conjunctiva like glue, and pulling it could cause a corneal abrasion. Flood your eye with preservative-free saline solution or rewetting drops.
Once the eye is lubricated, close your eyelid and gently—very gently—massage the lid in a circular motion. Think of it like nudging a piece of paper across a desk. You are trying to move the lens back toward the center of your eye where you can see it and grab it.
The Eyelid Flip
If massaging doesn't work, you might need to flip your lid. This sounds gross, but it's a standard technique used by optometrists. Place a Q-tip horizontally against the outside of your upper lid. Grab your eyelashes and gently pull the lid down and then fold it back over the Q-tip. This exposes the entire upper fornix. If the lens is there, it will usually be visible, and you can gently slide it down with a finger.
What If It’s Not There?
Sometimes, the lens isn't actually in your eye anymore.
This is the "phantom lens" effect. You might have actually blinked it out onto the floor or into the sink without realizing it. Because the lens was irritating the eye, your cornea might have a tiny scratch or just be generally inflamed. This creates a foreign body sensation.
Your brain is convinced something is in there because the nerve endings are firing. Dr. Thomas Steinemann, a clinical spokesperson for the AAO, often notes that patients frequently come in insisting a lens is stuck when they've actually just scratched their eye while trying to find it.
If you have used a full bottle of saline and flipped your eyelid and still see nothing, stop poking. You are likely doing more harm than good at that point.
When to See a Professional
You shouldn't mess with your eyes for more than 15 or 20 minutes. If the lens is still MIA and your eye is getting redder or more painful, it’s time to call an optometrist or go to an urgent care center.
They have a tool called a slit lamp. It’s basically a high-powered microscope that allows them to see every nook and cranny of the eye surface. They can also use a yellow dye called fluorescein. Under a blue light, this dye makes the contact lens (and any scratches on your eye) glow bright green. It makes finding a lost lens take about five seconds.
Don't feel embarrassed. Eye doctors see this every single day. It’s much better to have a professional take it out than to give yourself a serious infection or a "pseudomonas" ulcer by digging around with dirty fingernails.
Things You Should Absolutely Never Do
- Do not use tap water. Tap water contains microorganisms like Acanthamoeba that can cause sight-threatening infections. Only use sterile saline.
- Do not use tweezers. Metal or plastic tweezers near your open eye are a recipe for disaster.
- Do not let someone else "dig" for it. Unless they are a medical professional, they don't have the steady hand or the lighting required to do this safely.
- Do not ignore it. While the lens can't go behind your brain, it can cause a massive inflammatory response or an infection if left under the eyelid for days.
Preventing the "Lost Lens" Scenario
If this is happening to you constantly, your lenses might not fit correctly. Base curve and diameter matter. If a lens is too flat for your eye, it’s going to slide around. Talk to your doctor about a refitting.
Also, keep your eyes hydrated. If you work in an office with heavy air conditioning, use rewetting drops every few hours. Keeping that layer of moisture between the lens and the eye ensures the lens stays centered.
Actionable Next Steps
- Stop touching your eye immediately if it is becoming painful or increasingly red; you may have already removed the lens and are now feeling a scratch.
- Check your environment. Look on your shirt, the counter, or the floor. It’s highly probable the lens fell out during your initial attempt to remove it.
- Apply a cold compress. If your eye feels irritated after the lens is out, a cool, clean washcloth can help reduce swelling and discomfort.
- Schedule an appointment if the sensation of something being in your eye persists for more than 24 hours, as this indicates a corneal abrasion that might require antibiotic drops.
