Contact Lens Hygiene: Dos and Don’ts

Understanding the Importance of Contact Lens Hygiene

Maintaining proper contact lens hygiene is essential for preserving eye health and avoiding complications that can lead to serious eye conditions or vision loss. Poor contact lens hygiene can result in infections, inflammation, and damage to the eyes.

Diseases such as keratitis (inflammation of the cornea), conjunctivitis (pink eye), and dry eye syndrome are commonly associated with contact lenses. These infections can cause redness, pain, irritation, vision impairment, and, in severe cases, permanent vision loss. To prevent complications, it is crucial to practice proper lens care and maintain good hygiene habits.

Contact lens hygiene plays a vital role in preventing vision loss and other severe eye conditions. By following a strict cleaning and disinfecting routine, and avoiding common mistakes like sleeping in contact lenses or using them for swimming, you can minimize the risk of eye infections and damage.
Moreover, good contact lens hygiene practices contribute to maintaining overall eye health and enable you to enjoy the benefits of using contact lenses without experiencing complications or discomfort.

Proper Contact Lens Handling

Proper handling of contact lenses is essential for maintaining eye health and minimizing the risk of complications. Following the correct procedure for inserting and removing lenses can help reduce the likelihood of infections and damage to the eyes.

Inserting Contact Lenses

Before inserting the contact lenses, wash your hands thoroughly with soap and water and dry them with a clean towel. Then, locate the lens on your finger, ensuring that it is not inside out, by holding it up to the light or by feeling for the edges. Next, look in the mirror and gently pull your upper eyelid up with one hand and use the other hand to pull down the lower eyelid. With your eyes open wide, place the lens on the white part of the eye and gently release the eyelid.

Unintended Consequence: Inserting a lens that is inside out can cause discomfort and irritation. Always check the lens orientation before placing it on the eye.

Removing Contact Lenses

To remove the contact lenses, follow the same procedure of pulling the upper eyelid up and the lower eyelid down. Look up and place the index finger of your dominant hand on the lens, gently pressing down on the lens and sliding it towards the outer corner of your eye. Once the lens is off the center of the eye, use your thumb and index finger to pinch the lens and remove it.

Unintended Consequence: If you have difficulty removing the lens, avoid rubbing your eye or using excessive force, as this can scratch the cornea. It is better to seek professional help if you experience difficulties in removing your lenses.

Tips for Handling Lenses

To minimize the risk of contamination and damage to your lenses, follow these tips:

  • Wash your hands: Always wash and dry your hands thoroughly before handling your contact lenses, as dirt, oil, and bacteria can lead to complications and discomfort.
  • Keep nails short: Keeping your nails short can prevent accidental scratches or damage to the lenses and your eyes.
  • Safe handling environment: Avoid handling your lenses near sinks or in a dirty environment to minimize the risk of contamination from water or airborne particles.
  • Replace lenses on schedule: Follow the lens replacement schedule recommended by your eye care professional to maintain cleanliness and eye health.

Cleaning and Disinfecting Contact Lenses

Regularly cleaning and disinfecting your contact lenses is crucial to maintaining proper eye health and avoiding complications. Improper cleaning can lead to infections, eye damage, and even vision loss.

How to Clean Contact Lenses

The first step in cleaning your contact lenses is to ensure that your hands are washed and dried thoroughly. Use a mild, fragrance-free soap to wash your hands, and dry them with a clean towel to avoid any potential contamination from dirt and bacteria.

After cleaning your hands, remove your contact lenses from your eyes and place them in the palm of your hand. Apply a few drops of the appropriate lens care solution designed for cleaning contact lenses, and gently rub each lens with your fingers. The rubbing action helps remove any buildup or debris on the lens surface, which in turn keeps your lenses clearer and healthier.

Once you’ve thoroughly cleaned both lenses, rinse each lens with the same or different lens care solution to remove any remaining cleaning solution. You can then proceed to disinfect your lenses.

Disinfecting Contact Lenses

Disinfecting your contact lenses is crucial to prevent the growth of harmful microorganisms, and it typically requires a different solution than the one used for cleaning. To disinfect your contact lenses, place them in contact lens cases filled with a disinfecting solution overnight. This will sanitize them and ensure they are safe for use the following day.

It’s essential to keep in mind that not all contact lens solutions are designed for cleaning, disinfecting, and storing your lenses. It’s essential to check the instructions on the packaging or consult with your eye care professional to ensure you’re using the proper solutions for each step in the process.

Choosing the Right Solutions for Different Lenses and Conditions

Not all contact lens solutions are suitable for every lens material, type, or condition. For example, hydrogen peroxide-based solutions require careful handling and neutralization before being safe to use. Silicone hydrogel contact lenses may require specific solutions to maintain their cleanliness and performance. It is essential to follow the instructions from the lens manufacturer, as well as the recommendations from your eye care professional, when selecting the appropriate cleaning, disinfecting, and storing solutions for your lenses.

Proper Storage of Contact Lenses

Storing your contact lenses correctly is essential to maintaining good eye health and avoiding complications. Follow these tips to ensure your lenses are kept in a clean and sterile environment.

Using Proper Lens Cases and Containers

  • Always use a clean and sterile contact lens case. Replace your case every 3 months or as recommended by your eye care professional.
  • Make sure your lens case is the right size for your contact lenses. Improper fitting can result in damage to the lenses.
  • When travelling, use a portable contact lens case to transport your lenses and cleaning solution.

Discard Old Solution and Replace with Fresh Solution

  • Dispose of the old contact lens solution daily. Leaving solution in the case for multiple days can lead to the growth of bacteria.
  • Always store your contact lenses in a fresh solution that you’ve poured from a fresh bottle. Do not reuse old solution or mix it with the new one.
  • Never add fresh contact lens solution to old solution in the lens case. Always pour out the old solution first, and then add fresh solution.

Cleaning and Replacing Lens Cases

  • Clean your contact lens case with soap and water, then rinse thoroughly with distilled water. Be sure to use a case cleaner or soap specifically designed for cleaning contact lens cases.
  • Allow the case to air dry facing down on a clean, lint-free towel or surface. This helps prevent dust and other particles from contaminating the case.
  • Consider using a case air dryer or lens case sanitizer for a more thorough cleaning and disinfection process.
  • Replace your contact lens case every 3 months or as recommended by your eye care professional.

Avoiding Common Mistakes in Contact Lens Hygiene

While contact lenses are a safe and effective vision-correcting option for millions of people, improper care and handling can lead to infections and damage to the eyes. Here are some of the most common mistakes people make with contact lenses and how to avoid them.

Sleeping in Contact Lenses

One of the most common mistakes people make with contact lenses is sleeping in them. Wearing contact lenses while you sleep can deprive your eyes of oxygen, increasing the risk of developing an infection or corneal ulcers. It is important to follow the instructions given by your eye care professional and never sleep in contact lenses unless they are specifically designed for overnight wear.

Swimming or Showering in Contact Lenses

Another common mistake is swimming or showering with contact lenses. Water in pools, lakes, and even showers can contain bacteria and parasites that can stick to contact lenses and cause eye infections. Always remove your contact lenses before swimming or showering, and use goggles to protect your eyes.

Using Expired Contact Lenses or Solutions

Using expired contact lenses or solutions can also increase the risk of eye infections. It is important to replace your contact lenses and lens solution as recommended by the manufacturer and to never use a product after its expiration date. Check the packaging for expiration dates and dispose of products that are no longer usable.

Poor Hygiene

Poor hygiene can also lead to eye infections. To minimize the risk of contamination, always wash your hands thoroughly with soap and water before handling your contact lenses. Dry your hands with a clean towel, and avoid using hand sanitizers, which can leave a residue on your hands and lenses.

To maintain good contact lens hygiene, follow these tips:

  1. Never sleep in contact lenses unless they are designed for overnight wear.
  2. Remove contact lenses before swimming or showering.
  3. Replace contact lenses and solutions as recommended by the manufacturer.
  4. Wash your hands thoroughly with soap and water before handling contact lenses.
  5. Avoid using expired products.

By following these tips and recommendations from your eye care professional, you can avoid common mistakes in contact lens hygiene and maintain healthy eyes for years to come.

Recognizing Signs of Contact Lens Complications

Properly caring for your contact lenses is essential to maintaining good eye health and avoiding serious complications. However, even with the best hygiene practices, sometimes contact lens-related complications can occur. It’s important to be aware of the symptoms and to take prompt action if you experience any issues.

Symptoms of Common Contact Lens-Related Complications:

  • Redness
  • Pain
  • Blurred vision
  • Excessive tearing
  • Sensitivity to light
  • Discomfort in your eye

If you experience any of these symptoms, it is crucial to seek medical attention immediately. Delaying diagnosis and treatment can lead to serious health risks, including loss of vision.

Steps to Take if You Experience Symptoms:

  1. Remove your contact lenses immediately.
  2. If you can, insert your glasses to avoid straining your eyes.
  3. Schedule an appointment with your eye care professional as soon as possible.
  4. Avoid wearing your contact lenses until your eye care professional advises it is safe to do so.

Importance of Prompt Treatment:

Neglecting to seek medical attention for a contact lens-related complication can result in various serious health risks, including:

  • Infections like keratitis and conjunctivitis.
  • Eye injuries.
  • Vision loss or blindness.

Taking immediate action to address a contact lens complication and receiving proper medical treatment can significantly reduce the risk of these serious health risks and preserve your eye health and vision.

The Importance of Contact Lens Replacement and Follow-Up Care

To maintain good eye health and avoid complications associated with contact lens wear, it is essential to follow a proper replacement schedule and engage in regular follow-up care with an eye care professional. Doing so ensures that your contact lenses are appropriate for your eyes and lifestyle, and it allows your eye care professional to monitor your overall eye health and address any concerns as they arise. Let’s explore the importance of replacing contact lenses at the recommended intervals and scheduling routine follow-up appointments.

Adhering to a Proper Replacement Schedule

Contact lenses are designed to be worn and replaced according to specific guidelines set by the manufacturer, which can vary depending on the type of lenses being used. Failing to adhere to these guidelines can compromise the effectiveness and performance of the lenses and increase the risk of eye infections, discomfort, and other complications. Here are some general guidelines on replacement schedules for the most common types of contact lenses:

  • Daily Disposable Lenses: As their name suggests, daily disposable lenses should be discarded after each day of use and replaced with a fresh, new pair the following day. This schedule helps to minimize the buildup of protein, lipids, and other debris on the lenses, which can lead to eye infections and discomfort.
  • Disposable Lenses (biweekly or monthly): These lenses are designed to be worn for a specified period (typically two weeks or one month) before being discarded and replaced with new ones. It is crucial to follow the replacement schedule set by the manufacturer to ensure proper hygiene and lens performance.
  • Extended Wear Lenses: These lenses are often designed to be worn continuously for up to 30 days, with the option to remove and clean them periodically. While they may offer convenience, it is important to consult with your eye care professional to determine if these lenses are suitable for your eyes and follow their guidelines for replacement and care.

To ensure you are following the appropriate replacement schedule, consult with your eye care professional and refer to the guidelines provided by the manufacturer.

Scheduling Regular Follow-Up Appointments

In addition to adhering to the recommended replacement schedule, it is essential to schedule regular follow-up appointments with your eye care professional to monitor your eye health. These appointments allow your eye care professional to check for signs of infection, inflammation, or other complications and ensure that your contact lenses fit correctly. The American Optometric Association (AOA) recommends visiting your eye care professional at least once per year for a comprehensive eye exam, regardless of whether you wear contact lenses or not.

During these follow-up appointments, your eye care professional may:

  • Evaluate your vision and prescription to determine if changes are required in your contact lenses or eyeglasses
  • Assess the health and function of your tear film, as contact lens wear can exacerbate dry eye symptoms and discomfort
  • Examine the contact lenses themselves to ensure they are not damaged and are providing the appropriate level of oxygen transmission
  • Evaluate your overall eye health for signs of infection, inflammation, or other complications related to contact lens wear
  • Provide guidance and recommendations on the type and care of contact lenses that best suit your unique needs and lifestyle

It is important to actively engage with your eye care professional during these appointments and discuss any concerns or issues related to your contact lens wear. By working together, you and your eye care professional can design a customized solution that supports your eye health and meets your vision correction needs.

In conclusion, proper handling, cleaning, and storage of your contact lenses are vital to maintaining optimal eye health. Supplementing these habits with a consistent replacement schedule and routine follow-up care ensures that your contact lens-wearing experience remains comfortable, effective, and safe for your eyes. With the guidance of your eye care professional and adherence to recommended practices, you can enjoy clear, comfortable vision while minimizing your risk of complications and maintaining the long-term health of your eyes.
