10 Tips for Keeping Your Contact Lenses Safe and Clean

1. Wash Your Hands Thoroughly

Always wash your hands with soap and water before touching your contact lenses. This crucial step helps remove dirt, oils, and bacteria that could transfer to your eyes, potentially leading to infections. While hand sanitizer can be useful in a pinch, it is not as effective as thorough washing with soap and water, and may even leave behind residues. According to the Centers for Disease Control and Prevention (CDC), proper hand hygiene is essential for safe lens handling and reducing the risk of eye problems.

2. Clean Lenses with Recommended Solution

Always use the disinfecting solution recommended by your eye care professional to clean and store your contact lenses. Using water, saliva, or homemade mixtures can introduce harmful microorganisms and lead to serious eye infections. The American Optometric Association (AOA)

warns against using tap water or saliva, as these are not sterile and can contaminate your lenses. Approved solutions are specially formulated to disinfect and protect your eyes, so never substitute them with other liquids for any reason.

3. Never Sleep in Lenses Unless Prescribed

Sleeping in contact lenses not designed for overnight wear can significantly increase your risk of eye infections, including corneal ulcers. Only lenses specifically prescribed for extended or overnight wear are safe to use while sleeping.

Daily wear lenses must be removed before bedtime, as they are not made to allow enough oxygen to reach your eyes during sleep. The U.S. Food & Drug Administration (FDA) strongly advises following your eye care professional’s recommendations regarding lens wear schedules to protect your vision.

4. Replace Lenses as Directed

Always follow the replacement schedule provided by your eye care professional, whether your lenses are daily, bi-weekly, or monthly disposables. Overwearing contact lenses can lead to a buildup of deposits, reduced oxygen flow, and increased risk of eye infections or irritation.

Proper replacement ensures optimal comfort and eye health, while ignoring the schedule can cause serious complications. The Mayo Clinic emphasizes the importance of replacing lenses as recommended to prevent damage and maintain clear, healthy vision.

5. Clean and Replace Your Lens Case Regularly

Keeping your lens case clean is just as important as caring for your lenses. Rinse the case daily with fresh contact lens solution (never water), wipe it dry with a clean tissue, and leave it open to air-dry. Replace your lens case at least every three months to minimize the risk of microbial contamination and infections.

The American Academy of Ophthalmology stresses that regular cleaning and timely replacement of your lens case are crucial steps in maintaining safe lens use and protecting your eye health.

6. Avoid Water Exposure

Never expose your contact lenses to water from any source, including tap water, swimming pools, or hot tubs. Water can harbor dangerous microorganisms such as Acanthamoeba, which can cause severe infections like Acanthamoeba keratitis that may lead to vision loss.

For example, swimming with lenses in a public pool can dramatically increase infection risks. The CDC’s guidelines strongly recommend removing lenses before any water activities and never rinsing or storing them in water to keep your eyes safe.

7. Follow Proper Insertion and Removal Techniques

Using the correct techniques for inserting and removing your contact lenses helps prevent accidental damage and contamination. Always start with clean, dry hands and avoid using fingernails, which can tear lenses or introduce bacteria. Place the lens on the tip of your finger and check its orientation before gently placing it on your eye.

When removing, look upward and slide the lens down before pinching it out with gentle pressure. Avoid rushing or using excessive force. The American Academy of Ophthalmology offers detailed guides and videos for safe lens handling.

8. Don’t Share Your Lenses

Never share your contact lenses with anyone, not even family members or close friends. Sharing lenses can easily transfer bacteria, viruses, or fungi between users, increasing the risk of serious eye infections and complications. A case study published by the National Institutes of Health documented infections resulting from shared cosmetic lenses. The FDA strongly warns against sharing any type of contact lenses, as it can lead to preventable and potentially sight-threatening problems.

9. Monitor for Signs of Infection

Be alert to symptoms that may indicate an eye infection, such as redness, pain, excessive tearing, light sensitivity, or blurred vision. Promptly removing your contact lenses and seeking immediate medical attention can prevent more severe complications and protect your sight.

Ignoring early warning signs could lead to serious conditions that threaten long-term vision. The NHS provides a comprehensive list of signs and symptoms to watch for. When in doubt, always consult your eye care professional to ensure your eyes remain healthy and safe.

10. Schedule Regular Eye Exams

Regular eye exams are essential for all contact lens wearers. Routine check-ups ensure that your lenses fit properly, your eyes stay healthy, and your prescription remains accurate. Early detection of changes or issues can prevent discomfort and complications.

The American Optometric Association recommends annual comprehensive eye exams, or as often as your eye care professional suggests. These visits allow your doctor to monitor for any conditions or infections and to update your care routine as needed for optimal eye health.

Conclusion

Consistent and proper contact lens care is vital for maintaining healthy eyes and clear vision. By practicing good hygiene, using recommended solutions, and following your eye care professional’s instructions, you significantly reduce the risk of infections and complications.

Regularly monitoring for symptoms and scheduling routine eye exams also play a critical role in protecting your sight. For more guidance on safe contact lens practices, visit the CDC’s contact lens safety resource. Prioritizing these habits ensures your eyes remain comfortable, healthy, and safe.
