Why Is My Contact Lens Disappearing Into My Eye?

Contact lens has slipped into the eye?

Doctor, my contact lenses are clear, and while wearing them, one lens went behind my eyeball.
However, my right eye can see exceptionally clearly, and there is no discomfort.
What could be the reason for this? Should I see an ophthalmologist?

Under normal circumstances, contact lenses do not get lost in the eye; it is best to check.

More Info

When you mention that your contact lens seems to be "disappearing" into your eye, it raises a few important considerations regarding the fit and positioning of the lens, as well as the overall health of your eye. First and foremost, it’s essential to clarify that contact lenses should never actually move behind the eyeball or become lost within the eye. They are designed to rest on the surface of the cornea, which is the clear front part of the eye. If you feel that your lens is not in the correct position, it could be due to a few factors.

1. Lens Fit and Type: The fit of your contact lens is crucial. If the lens is too loose or too tight, it may not sit properly on your eye. This can lead to discomfort or the sensation that the lens is moving around too much. You mentioned that your right eye is seeing clearly, which might indicate that the lens is positioned correctly at that moment, but it could also mean that the lens is not adhering properly to the surface of the eye, especially if it feels like it’s slipping or moving.

2. Dryness and Tear Film: One common issue that can cause contact lenses to feel like they are disappearing is dry eyes. If your eyes are not producing enough tears, or if the tear film is unstable, the lens may not stay hydrated and can shift more easily. You mentioned experiencing dryness in your eyes, which could exacerbate this issue. Using artificial tears or lubricating eye drops specifically designed for contact lens wearers can help maintain moisture and improve comfort.

3. Corneal Health: If you have a history of high myopia (nearsightedness) or other eye conditions, it’s essential to ensure that your cornea is healthy. Any irregularities in the cornea, such as astigmatism or keratoconus, can affect how the lens sits on your eye. If you have concerns about your corneal health, it would be wise to consult with an eye care professional.

4. Lens Material: The material of the contact lens can also play a role in how it interacts with your eye. Some lenses are designed to be more breathable or to retain moisture better than others. If you have recently switched brands or types of lenses, this could be a factor in your experience.

5. Eye Examination: Given your symptoms and concerns, it is advisable to see an eye care professional. They can perform a thorough examination to assess the fit of your lenses, the health of your cornea, and the overall condition of your eyes. They may also check for any signs of irritation or infection that could be contributing to your discomfort.

In conclusion, while it may feel like your contact lens is disappearing into your eye, it is likely a matter of fit, dryness, or lens material. It is essential to address these issues promptly to avoid any potential complications. Regular check-ups with your eye care provider will ensure that your lenses are appropriate for your eyes and that your eye health is maintained. If you experience any pain, redness, or persistent discomfort, do not hesitate to seek immediate medical attention.

Answer: Displacement of contact lenses, especially when they move towards the upper fornix of the eye, is mostly caused by the glasses being too loose. You can ask an optical shop to adjust them or consult a physician for an examination.
