If you’re not sure whether your contact lens is still in your eye, the quickest check is to cover the other eye and see if your vision in the questionable eye is sharper than your uncorrected sight normally is. A lens that’s still present will correct your vision even if it has shifted off-center. Beyond that simple test, a combination of physical sensations, a visual inspection, and a search of your surroundings can give you a definitive answer.
The Quick Vision Test
Close or cover the eye you’re not worried about. Look at something with small text, like your phone screen, using only the eye in question. If you can read clearly at the distance you’d normally need correction for, the lens is almost certainly still in there, even if it feels odd. If your vision is back to its usual uncorrected blur, the lens likely fell out.
This test isn’t perfect for people with mild prescriptions, since the difference between corrected and uncorrected vision can be subtle. In that case, you’ll need to rely on physical signs and a direct inspection.
What a Stuck Lens Feels Like
A contact lens that has slid off your cornea but is still somewhere on the surface of your eye typically causes blurred vision in that eye and a noticeable discomfort. The sensation is often a foreign-body feeling, like something gritty or slightly sharp is pressing against the inside of your eyelid, especially when you blink. You may also notice localized redness or extra tearing on that side.
Here’s what makes this tricky: a small scratch on your cornea (a corneal abrasion) can produce the exact same sensation. Even after a lens has successfully come out, a tiny scratch left behind can make it feel like something is still in your eye with every blink. The American Academy of Ophthalmology notes that dry eyes, retained foreign particles, and corneal abrasions can all mimic the feeling of a lens being present. So discomfort alone isn’t proof the lens is still there. You need to look.
How to Visually Inspect Your Eye
Wash your hands thoroughly with soap and water and dry them on a lint-free towel. Stand in front of a well-lit mirror, or use your phone’s front camera with the brightness turned up.
- Check the cornea first. Look straight ahead. A lens sitting correctly on your cornea can be hard to spot, but one that’s slightly displaced will show a visible edge, often as a faint curved line across the white of your eye.
- Look in all four directions. While holding your eyelids open, look up, down, left, and right. A displaced soft lens often slides toward the inner corner of the eye or tucks under the upper lid. As you move your gaze, you may see the lens edge shift into view.
- Check under the lower lid. Gently pull your lower eyelid down while looking up. The pocket between your eyeball and lower lid is easy to inspect and is a common hiding spot.
- Check under the upper lid. This is where lenses most often get lost. Look downward, then use your fingertips to gently flip your upper eyelid upward over itself. Research on lid eversion techniques found that using fingers alone is the most comfortable method for patients. You don’t need a cotton swab. With the lid flipped, look for the lens tucked against the pink tissue underneath.
It Can’t Go Behind Your Eye
A common fear is that the lens has slipped behind the eyeball and into your head. This is physically impossible. A thin membrane called the conjunctiva lines the inside of your eyelids and folds back to cover the white of your eye, creating a sealed pocket. There is no open pathway from the front surface of your eye to the space behind it. The farthest a lens can travel is into the upper or lower fold of that pocket, where it will sit until you retrieve it or it works its way out on its own.
How to Get a Stuck Lens Out
If you’ve confirmed the lens is still in your eye, don’t try to pinch it off the surface immediately, especially if it feels dried out or stuck. A dehydrated soft lens can grip the eye’s surface, and pulling at it can scratch your cornea.
Start by applying several drops of sterile saline solution or rewetting drops made for contact lenses. Tilt your head back, let the drops flow into your eye, and blink a few times to spread the moisture around. Give the drops two to three minutes to rehydrate the lens before you try again. Once the lens feels mobile, you should be able to slide it back onto your cornea and remove it normally.
If drops alone don’t free it, gently massage through your closed eyelid with clean fingertips. The goal is to nudge the lens toward the center of your eye where you can reach it. Work slowly and with light pressure. Forceful rubbing can push the lens deeper into the upper fold or irritate the surrounding tissue.
Check Your Surroundings
Before assuming the lens is trapped in your eye, consider that it may have fallen out without you noticing. Soft lenses are thin, transparent, and almost invisible on most surfaces. Two tricks make finding a dropped lens much easier.
First, use a small flashlight or your phone’s flashlight and sweep it at a low angle across the floor, countertop, or sink where you were standing. A contact lens reflects light differently than the surface beneath it, making it suddenly obvious when the beam hits it at the right angle. Second, if it fell on the floor, get down and lay your head flat against the ground, looking sideways across the surface. Anything that isn’t perfectly flat, including a tiny lens, will stand out in silhouette against the floor plane.
Check your clothing too, especially your collar, sleeves, and the front of your shirt. Lenses frequently land on fabric and cling there without being felt.
When Discomfort Lingers After the Lens Is Out
If you’ve confirmed the lens is out (either by finding it or by verifying your vision is uncorrected) but your eye still feels irritated, the most likely explanation is a minor corneal abrasion. These small scratches heal on their own within a day or two. Your eye may feel gritty, watery, and sensitive to light in the meantime.
Redness and pain that persist for more than a few hours after the lens is removed are worth a call to your eye care provider. Prolonged irritation can signal a deeper scratch or early infection, both of which benefit from prompt treatment. The same applies if you’ve tried the steps above and still can’t determine whether the lens is in your eye. An eye care provider can use a slit lamp to locate a lens in seconds, even one buried deep in the upper fold, and remove it safely.
