Many contact lens wearers worry a lens might get lost behind the eye. While a contact lens can certainly move from its central position on the cornea, it is physically impossible for it to get truly “lost” behind the eyeball itself. This article will clarify why this cannot happen and provide practical steps for managing dislodged lenses.
Understanding Eye Anatomy
The eye’s anatomy includes a protective membrane called the conjunctiva, which prevents foreign objects, including contact lenses, from migrating behind the eyeball.
This thin, transparent mucous membrane lines the inner surface of your eyelids (palpebral conjunctiva) and then folds back to cover the white part of your eye (bulbar conjunctiva), stopping at the edge of the cornea. This continuous structure forms a natural barrier, often referred to as the conjunctival sac, which effectively seals off the back of the eye.
The membrane is loosely attached over the sclera, allowing for eye movement, and it contains goblet cells that produce mucus, contributing to the tear film that keeps the eye lubricated.
When Lenses Feel Lost
When a contact lens feels “lost” in the eye, it typically means it has moved from its intended position. Common scenarios include the lens being dislodged to the side of the eye, folded, or tucked under an eyelid.
A reason for a soft contact lens getting stuck or feeling lost is dehydration, which can cause it to adhere to the eye’s surface. This often occurs from extended wear or sleeping in lenses.
To locate and safely remove a misplaced lens, begin by thoroughly washing your hands to prevent introducing contaminants to your eye. If the lens feels centered but stuck, it is likely dried out; apply several drops of sterile saline solution or rewetting drops suitable for contacts to rehydrate the lens and your eye. Blink repeatedly to help moisturize and gently dislodge the lens, and you can also try gently massaging your closed upper eyelid. This process might take several minutes, as the lens needs time to rehydrate and become pliable again.
If the lens has moved off-center or under an eyelid, look in the opposite direction of where you suspect the lens is located. For example, if it feels lodged under your upper eyelid, look down. Gently massage your eyelid while blinking frequently to encourage the lens to move back to the center of your eye. Once the lens is visible and moves freely, you can remove it as you normally would. For rigid gas-permeable (RGP) lenses, avoid massaging the eye, as their harder structure could scratch the cornea; instead, gently press just outside the edge of the lens with a fingertip to break the suction.
When to Consult a Professional
Most dislodged contact lenses can be safely removed at home with patience and proper technique. However, there are specific situations where seeking professional medical attention from an eye care specialist is advisable. If you have attempted to remove a stuck lens multiple times and it remains lodged, or if you cannot locate it after trying the recommended steps, an optometrist or ophthalmologist can safely retrieve it.
You should also consult an eye care professional if you experience persistent symptoms after a lens incident, even if you successfully removed the lens. These symptoms can include ongoing pain, redness, blurred vision, excessive tearing, or any unusual discharge from the eye. These signs might indicate irritation, a corneal abrasion, or even an infection, which requires prompt medical evaluation and treatment to prevent further complications.
