A common concern for contact lens wearers is a lens getting stuck or lost behind the eye. While unsettling, it is impossible for a contact lens to become permanently lost behind the eye due to the eye’s natural anatomy. The feeling of a stuck lens is usually caused by other, manageable issues.
Understanding Eye Anatomy and Contact Lenses
The eye possesses a protective membrane called the conjunctiva, which prevents foreign objects, including contact lenses, from going behind the eyeball. This thin, moist lining covers the inner surface of the eyelids and folds back to cover the white part of the eyeball. This continuous barrier creates a natural pocket, ensuring a contact lens can only shift to the upper or lower eyelid, but cannot pass beyond the front of the eye.
Common Reasons Lenses Feel Stuck
Several factors can cause a contact lens to feel stuck, even if it remains on the eye’s surface. A frequent reason is dryness, which can cause the lens to adhere tightly. This often occurs if lenses are worn for extended periods, especially overnight, or in dry environments. The lack of moisture can make the lens less pliable and more difficult to remove.
A lens might also feel stuck if it has become displaced, sliding from the cornea to lodge under an eyelid. This can happen if the eye is rubbed vigorously or if the lens is not properly centered during insertion. The sensation of a displaced lens may feel present but not be immediately visible.
Foreign particles or debris entering the eye can cause irritation and make the lens feel stuck. Even a small speck under the lens can lead to discomfort. A damaged lens, such as one that is folded or torn, can also create a “stuck” sensation and cause irritation. Over-wearing lenses beyond their recommended schedule can lead to discomfort and difficulty in removal, as lenses can accumulate deposits and become less hydrated over time.
Steps for Safe Removal
When a contact lens feels stuck, stay calm; panicking can cause the eyelids to tighten. Begin by washing hands with soap and water, then drying them with a lint-free towel to prevent introducing contaminants to the eye. Next, lubricate the eye with rewetting drops, sterile saline solution, or multipurpose contact lens solution; this helps rehydrate the lens and loosen its grip. Blink several times to distribute the drops and encourage the lens to move.
Locate the lens by looking in a mirror under good lighting. If the lens is off-center, try looking in the opposite direction of where it is stuck. Gently massage the closed upper eyelid in a circular or downward motion to help dislodge the lens and guide it back to the center. Once the lens is re-centered or on the white part of the eye, use standard removal techniques. For soft lenses, gently pinch the lens between the pads of your thumb and index finger, or slide it down to the white of your eye and then pinch it off.
If the lens remains stuck despite these efforts, or if there is persistent pain, redness, or vision changes after removal, seek professional help from an eye doctor. They can safely locate and remove the lens, and assess for any potential damage to the eye.
Tips for Prevention
Preventing contact lenses from feeling stuck involves adhering to proper care routines and wearing habits. Always wash hands with soap and water before handling lenses to minimize the transfer of oils, germs, or dirt to the eye. Regularly using rewetting drops throughout the day can help prevent lenses from drying out and adhering to the eye, especially for individuals prone to dry eyes.
Adhering to the recommended wearing schedule for your specific type of lenses is important. Over-wearing lenses, particularly sleeping in daily wear lenses, can lead to dryness, discomfort, and increased risk of the lens feeling stuck. Proper insertion and removal techniques ensure the lens is correctly placed and gently handled, preventing displacement or damage. Regular eye exams with an eye care professional ensure proper fit, monitor overall eye health, and detect any issues.
