Panic is usually the first thing that hits. You go to take your lens out, you pinch at the air, and suddenly, it’s gone. It isn't on your finger. It isn't on the bathroom floor. You’re staring into the mirror, eye getting redder by the second, convinced the thin piece of plastic has somehow slid into the dark abyss behind your brain. Honestly, it’s a terrifying sensation. But here is the reality: your eye is a sealed pocket. It’s physically impossible for a contact stuck in eyelid to migrate behind your eye because of a membrane called the conjunctiva.
That doesn't make it feel any less like a pebble is grinding into your skull.
When a lens gets lost up there, it’s usually folded over itself, hiding in the superior fornix—the deep pocket of the upper eyelid. It’s a common mishap, especially if you’ve rubbed your eyes too hard or fallen asleep in lenses not rated for overnight wear. Most people start poking and prodding aggressively, which is the worst thing you can do. You’ll likely scratch your cornea before you ever find the lens.
Why Lenses Go Rogue
It’s mostly physics. Your eye is lubricated by a tear film that’s only a few microns thick. If that film dries out—maybe because of a long flight or staring at a MacBook for eight hours—the lens loses its suction to the cornea. It gets "tacky." When you blink or rub your eye, that tacky lens catches on the underside of your eyelid and gets dragged upward.
Soft lenses are the usual suspects here because they are incredibly thin and flexible. They can roll up like a tiny burrito. Rigid Gas Permeable (RGP) lenses are different; they don't fold, but they can suction onto the white of your eye (the sclera) with surprising force. I've seen patients come in convinced they have a "growth" on their eye, only for it to be a hard lens that’s been suctioned to the side of the globe for three days.
According to the American Academy of Ophthalmology, the most common reason for a lost lens is simply improper handling. But sometimes, it’s just bad luck. You sneeze, your eye squeezes shut, and the lens migrates. It happens.

The "Flush and Flip" Method
Don't go in with tweezers. Just don't. I know the temptation to grab something sharp to "hook" the edge is strong when you're frustrated, but you're dealing with tissue that heals slowly and scars easily.
First, wash your hands. Use a mild soap, nothing with heavy perfumes or oils that will sting your eye even more. Now, stand in front of a well-lit mirror. Look down as far as you can. Use one finger to pull your upper eyelid upward and outward. Often, just changing the tension of the lid is enough to let the lens drop back down onto the colored part of your eye.
If that fails, you need saline. Not tap water. Never use tap water because of Acanthamoeba, a nasty little parasite that loves to eat corneal tissue. Flood the eye with sterile saline solution or rewetting drops. You want the eye to be "swimming." While the eye is wet, close your lids and gently—very gently—massage the upper lid in a downward motion toward the pupil.
- Step 1: Look down and pull the lid up.
- Step 2: Use a mirror and a flashlight (your phone works) to look for a subtle ridge.
- Step 3: If you see it, use a clean finger to slide it toward the center.
- Step 4: If you can't see it, it might be folded under the lid.
Sometimes you have to "evert" the eyelid. This sounds gross, but it’s what eye docs do. You place a Q-tip horizontally on the outside of your upper lid, grab the lashes, and fold the lid back over the Q-tip. It exposes the "underside." If the contact stuck in eyelid is there, you’ll see it immediately. It’ll look like a gelatinous blob.
The Myth of the Vanishing Lens
We’ve all heard the urban legends. The woman who had 27 contact lenses stuck in her eye? That actually happened. In 2017, the British Medical Journal reported on a 67-year-old woman scheduled for cataract surgery. The surgeons found a "bluish mass" that turned out to be 17 lenses stuck together, and then found 10 more. She thought her discomfort was just old age and dry eyes.

This happens because the eye can sometimes "numb" itself to the presence of a foreign body over time. If a lens stays stuck long enough, the mucus in your eye can coat it, making it feel less sharp and more like a dull ache. But for 99% of people, a lost lens feels like an emergency because the cornea is one of the most nerve-dense parts of the human body.
If you’ve tried flushing and massaging and you still feel something, you might be dealing with a corneal abrasion. Basically, you’ve scratched the surface of the eye. The annoying part is that a scratch feels exactly like a stuck contact lens. Your brain can't tell the difference between "there is something in my eye" and "my eye is damaged."
When to Call a Professional
If your vision is blurry, if there is yellow discharge, or if the pain is making it impossible to keep your eye open, stop. You’re done with the DIY approach.
An optometrist has a slit lamp—a high-powered microscope—that can see things you never will in a bathroom mirror. They can use a special dye called fluorescein. Under a blue light, this dye glows bright green and pools around any foreign objects or scratches. It makes a hidden lens pop like a neon sign.
- Go to the ER or an Eye Doc if:
- The eye is beefy red.
- You see a white spot on the cornea (this could be an ulcer).
- The pain persists for more than two hours after you think you got the lens out.
- You used tap water or spit to try and lubricate the eye (huge infection risk).
Most of the time, the doctor will just numb the eye with Proparacaine drops, use a small tool to flick the lens out, and send you home with some antibiotic drops. It’s a five-minute fix that saves you days of agony.

How to Stop This From Happening Again
Prevention is boring but effective. Most "lost" lenses are the result of dryness. If your eyes feel gritty by 4 PM, you shouldn't be wearing those lenses until 10 PM. Use preservative-free artificial tears throughout the day to keep the lens "floating" properly on the tear film.
Also, check your technique. If you’re a "rubber," try to break the habit. If your eye itches, press firmly on the inner corner (near the nose) instead of grinding your knuckles into the globe. This keeps the lens centered.
Lastly, replace your lenses on schedule. Old lenses accumulate protein deposits. These deposits make the surface of the lens "sticky" to the palpebral conjunctiva (the lining of the eyelid). A fresh lens is a slippery lens, and a slippery lens stays where it’s supposed to be.
Moving Forward Safely
If you’ve managed to get the contact stuck in eyelid out, do not put a new lens in immediately. Give your eye at least 24 hours to recover. Your tear film needs to re-establish itself, and any minor micro-scratches need time to knit back together.
Actionable Next Steps:
- Check the lens for damage: If you recovered the lens and it’s torn, there might still be a small fragment in your eye. Look at the edges closely.
- Use Lubricant: Put in some preservative-free artificial tears every hour for the next four hours. This soothes the irritation and helps flush out any debris.
- Monitor for the "Sand" Sensation: If it still feels like sand is in your eye tomorrow morning, you likely have a corneal abrasion and need a quick check-up to ensure it doesn't get infected.
- Dispose of the "stuck" lens: Even if it looks fine, it's likely been contaminated or warped. Toss it and start fresh tomorrow.
Don't panic if you can't find it immediately. Take a breath, wait ten minutes for the natural tear production to kick in, and try the looking-down-while-pulling-the-lid-up trick again. It usually works when you aren't frantic.
