White Film Over Vision After Sleeping in Contacts - Ophthalmology

Waking up with a white film over your vision after sleeping in contact lenses is a common issue that can be attributed to several factors related to the health of your eyes and the proper use of contact lenses. When you sleep with contact lenses in, especially if they are not designed for extended wear, your eyes can become deprived of oxygen. This lack of oxygen can lead to a condition known as corneal edema, where the cornea swells due to fluid accumulation.
The cornea is the clear front part of the eye that allows light to enter and is crucial for clear vision. When it becomes swollen, it can cause visual disturbances, including the appearance of a white or cloudy film over your vision. This is because the swelling affects the way light is refracted as it passes through the cornea, leading to blurred or hazy vision.
In addition to corneal edema, sleeping in contact lenses can also lead to dryness and irritation of the eyes. Contact lenses can absorb tears and moisture from the surface of the eye, which can exacerbate dryness, especially during sleep when tear production decreases. This dryness can further contribute to the sensation of a film over your vision.

Another factor to consider is the potential for bacterial or fungal infections. Sleeping in contact lenses increases the risk of developing infections, which can also manifest as visual disturbances. If you notice persistent symptoms, such as redness, pain, or significant changes in vision, it is crucial to seek medical attention from an eye care professional.

To mitigate these issues, it is essential to follow proper contact lens hygiene and usage guidelines. Here are some recommendations:
1. Remove Contact Lenses Before Sleeping: Unless you are using lenses specifically designed for overnight wear, always remove your lenses before going to bed. This allows your corneas to receive adequate oxygen and reduces the risk of complications.

2. Use Proper Lens Care Solutions: Always clean and store your lenses in the appropriate solution recommended by your eye care provider. Avoid using water or saliva to clean your lenses, as these can introduce harmful microorganisms.

3. Stay Hydrated: Ensure that you are drinking enough water throughout the day to maintain overall hydration, which can help keep your eyes moist.

4. Regular Eye Check-ups: Schedule regular appointments with your eye care professional to monitor your eye health and ensure that your contact lenses are suitable for your eyes.

5. Consider Daily Disposables: If you frequently experience discomfort with your current lenses, you might want to consider daily disposable lenses, which can reduce the risk of buildup and irritation.

If you continue to experience symptoms like a white film over your vision after removing your contact lenses, or if the symptoms worsen, it is important to consult with an eye care professional. They can perform a thorough examination to rule out any underlying conditions and provide appropriate treatment or recommendations tailored to your specific needs. Remember, your eye health is paramount, and taking proactive steps can help maintain clear and comfortable vision.
