How to Take Care of Your Contact Lenses

Why Contact Lens Hygiene Matters

Contact lenses sit directly on the surface of your eye. This creates a direct pathway for bacteria, fungi, and other microorganisms to enter the eye if lenses are not kept clean. Improper lens care can lead to conditions like keratitis (corneal inflammation), corneal ulcers, and serious infections that may cause vision loss.

Many of these complications are preventable through proper hygiene and responsible habits. That’s why your daily contact lens routine matters just as much as the lenses themselves.

Clean Hands, Clear Vision

Before touching your contact lenses, always wash your hands thoroughly with soap and water. Dry them with a lint-free towel. This simple step is one of the most effective ways to prevent the transfer of germs and dirt to your eyes.

Avoid moisturizing soaps or hand sanitizers that contain oils or lotions, as these can leave a film on your lenses and reduce clarity or increase irritation.

Use the Right Solutions

Never use tap water, saliva, or homemade saline solutions to clean your lenses. Always use a sterile, commercially prepared solution recommended by your eye care professional. These solutions are specifically formulated to disinfect lenses and remove buildup safely.

Contact Lens Care Dos and Don’ts

Here are two quick-reference lists to help you stay on track:

Top 6 Contact Lens Hygiene Dos

1. Wash and dry your hands before inserting or removing lenses.
2. Use fresh contact lens solution every time—never top off old solution.
3. Clean your lens case with solution and let it air dry daily.
4. Replace your lens case every 1 to 3 months.
5. Follow the wearing schedule recommended by your eye care provider.
6. Remove lenses before swimming unless using prescription swim goggles.

Top 6 Contact Lens Hygiene Don’ts

1. Don’t sleep in lenses unless they’re specifically approved for overnight wear.
2. Don’t rinse or store lenses in water of any kind.
3. Don’t reuse old solution or transfer it between bottles.
4. Don’t use expired contact lens solution.
5. Don’t wear lenses longer than prescribed or past their replacement date.
6. Don’t ignore discomfort, redness, or blurred vision—remove the lenses and seek care.

Sleeping in Contacts: A Risky Shortcut

Even just a few hours of overnight wear in non-approved contacts can increase your risk of corneal hypoxia—a condition caused by reduced oxygen reaching the cornea. This can lead to discomfort, blurred vision, and a higher chance of infection.

Only wear lenses overnight if they are specifically designed and prescribed for extended use, and even then, make sure you follow up regularly with your eye doctor.

Know When to Replace Your Case

Your contact lens case can harbor bacteria if not replaced regularly. Even if it looks clean, invisible microbial buildup can pose a serious risk to your eye health. Mark your calendar to change your case at least every 3 months, or sooner if it becomes cracked, cloudy, or difficult to clean.

Pay Attention to Your Eyes

If your eyes become red, irritated, watery, or your vision changes unexpectedly, take your lenses out immediately and contact your eye care provider. Never try to “wait out” a problem when it comes to your eyes. Early intervention can prevent more serious complications.

Healthy Habits Make All the Difference

Contact lenses offer freedom and flexibility, but only when paired with proper care. By committing to a daily routine that includes clean hands, appropriate cleaning solutions, and responsible wear, you dramatically reduce your risk of infection and protect your long-term vision.
