Eye Infections from Contact Lenses

Contact lenses are a convenient option for vision correction, but they can sometimes lead to eye infections if not used properly. Understanding the potential risks, practicing effective hygiene, and exploring alternatives like LASIK can help users avoid these problems. Below, we’ll discuss common causes, symptoms, and how to minimize risks associated with contact lens use.

What Is Keratitis and Why Is It a Concern for Contact Lens Users?

Keratitis, an infection of the cornea, is a frequent issue for contact lens wearers. This condition can cause significant discomfort, and in severe cases, corneal scarring. If left untreated, scarring may impair vision, sometimes requiring a corneal transplant to restore clear sight. The risk is higher among those who don’t adhere to recommended care practices for their lenses.

Main Causes of Contact Lens-Related Eye Infections

A variety of factors contribute to infections among contact lens users. Key causes include:

1. Extended Lens Use: Wearing lenses longer than recommended can restrict oxygen flow and allow bacteria to accumulate.
2. Sleeping with Lenses In: Overnight lens wear (when not designed for it) often leads to increased bacterial exposure, raising infection risks.
3. Contamination from Microorganisms: Fungi, bacteria, and other microorganisms can easily get trapped under contact lenses, causing infections such as bacterial or fungal keratitis.
4. Inadequate Cleaning: Failure to clean lenses or cases properly allows microbes to grow, increasing the risk of eye infections.
5. Water Exposure: Contact with water, including tap water or while swimming, can introduce harmful organisms to lenses.

Recognizing the Signs of an Eye Infection from Contacts

Recognizing symptoms early can help prevent complications. Be alert to the following signs:

• Blurred or cloudy vision
• Redness or inflammation of the eye
• Discomfort, pain, or burning sensations
• Watery or sticky discharge
• Light sensitivity
• Persistent feeling of an object in the eye

If you experience any of these symptoms, consult your eye care provider immediately to address potential infections and avoid further damage to your vision.

Tips for Preventing Contact Lens-Related Infections

Preventing eye infections starts with good lens care habits. Follow these essential practices:

1. Replace Lenses Regularly: Follow your lens replacement schedule precisely. Overextending the use of contacts can lead to eye strain and infection.
2. Clean Properly: Use a disinfecting solution each time you store lenses. Avoid topping off or reusing old solution, as this can lead to contamination.
3. Care for Storage Cases: Clean cases regularly and replace them every three months to avoid bacterial buildup.
4. Avoid Sleeping in Contacts: Remove lenses before bed unless specifically designed for overnight wear.
5. Stay Away from Water: Keep lenses out of water, whether it’s from the shower, swimming pool, or tap.

Should You Consider LASIK?

If you’ve struggled with contact lens-related infections or find them cumbersome, LASIK could offer a convenient alternative. LASIK is a laser procedure that corrects vision by reshaping the cornea, removing the need for daily lens use. Beyond convenience, LASIK reduces the chances of infection since it eliminates the daily handling of lenses, cleaning, and storage.

Final Thoughts on Preventing Eye Infections from Contacts

While millions wear contacts safely every day, proper hygiene and consistent practices are crucial to avoid infections. Those looking for a more permanent solution may find LASIK a suitable alternative, freeing them from daily lens care routines and the risk of recurrent infections. Always consult an eye care specialist to determine the best options for your vision and eye health.
