Essential Tips for Proper Contact Lens Cleaning and Care

Cleaning of Contact Lenses

I saw news about Acanthamoeba parasites today and realized how important it is to clean contact lenses.
I just started wearing contact lenses for the first time last week, and I would like to ask the doctor if there is a specific procedure for cleaning contact lenses.
Are there any important points to pay attention to when cleaning them? I've heard that saline solution can be used to soak the lenses, so why do we still need contact lens solution? Also, should I avoid wearing them for too long each day? How often should I change the lens case? Since this is my first time wearing them, I have many questions and would appreciate your guidance.
Thank you!

Contact lenses should be cleaned by rubbing them with your hands daily; do not overly rely on cleaning cases.
Protein removal with enzymes should be done weekly.
Saline solution cannot prevent microbial contamination, and solutions containing chemical agents should be rinsed with saline before wearing.
Replace the storage case approximately every six months, depending on its condition.
Additionally, contact lenses are only suitable for short-term special needs and should not replace regular glasses, as long-term use of contact lenses can be harmful to eye health.

More Info

When it comes to proper contact lens cleaning and care, especially with the recent news about Acanthamoeba keratitis, it's crucial to follow a strict regimen to ensure your eye health. Here are some essential tips and guidelines for cleaning and maintaining your contact lenses, particularly soft, extended-wear lenses.

Daily Cleaning Routine
1. Use the Right Solution: Always use a contact lens solution specifically designed for cleaning and disinfecting lenses. Saline solution or homemade saline (like saline used for nasal irrigation) is not suitable for cleaning lenses as it does not have the necessary disinfecting properties. Contact lens solutions contain preservatives and surfactants that help remove debris and kill bacteria.

2. Daily Replacement of Solution: If you are not wearing your lenses daily, it is still important to change the solution every day. Leaving lenses in old solution can lead to bacterial growth and loss of disinfecting properties. Ideally, you should replace the solution every 1-2 days if the lenses are not being worn.

3. Rinse Before Wearing: Before putting your lenses back in, rinse them with fresh solution. This step helps remove any buildup that may have occurred while the lenses were stored.

4. Hand Hygiene: Always wash your hands thoroughly with soap and water before handling your lenses. Dry your hands with a lint-free towel to avoid transferring any particles to your lenses.

5. Avoid Water Contact: Never rinse your lenses with water, including tap water or bottled water. Water can introduce harmful microorganisms that can lead to serious eye infections.

Storage and Handling
1. Lens Case Maintenance: Replace your contact lens case every three months. Clean the case with fresh solution (not water) and allow it to air dry. This helps prevent contamination.

2. Avoid Sleeping in Lenses: Unless specifically designed for overnight wear, avoid sleeping in your contact lenses. Doing so increases the risk of eye infections and complications.

3. Limit Wearing Time: Follow the recommended wearing schedule provided by your eye care professional. Overwearing lenses can lead to discomfort and increased risk of complications.

Protein Removal
1. Regular Cleaning: Depending on your lens type and wearing schedule, you may need to use a protein remover solution every 1-2 weeks. This helps remove protein deposits that can accumulate on the lenses over time.

2. Consult Your Eye Care Provider: If you notice discomfort, redness, or changes in vision, consult your eye care provider immediately. They can provide tailored advice based on your specific needs and lens type.

Additional Considerations
- Avoid DIY Solutions: While saline solutions might seem convenient, they lack the necessary disinfecting properties to keep your lenses safe. Stick to commercially available contact lens solutions.

- Be Mindful of Symptoms: If you experience symptoms like excessive tearing, redness, or discomfort, it may indicate an issue with your lenses or an eye infection. Seek professional advice promptly.

- Education is Key: Since you are new to wearing contact lenses, consider scheduling a follow-up appointment with your eye care provider. They can provide additional education on lens care and address any specific concerns you may have.

In summary, proper contact lens care is essential for maintaining eye health and preventing infections. By following these guidelines and consulting with your eye care professional, you can enjoy the benefits of contact lenses while minimizing risks. Always prioritize hygiene and be proactive about your eye health.
