Overwearing lenses or using them incorrectly can lead to irritation, infections, or even more severe complications.

In this guide, we’ll explore how long you can safely wear contact lenses, the key factors influencing wear time, and best practices to ensure your eyes stay healthy. 

Whether you’re new to contact lenses or a seasoned user, there’s something here for everyone.

How Long Can You Safely Wear Contact Lenses?

The length of time you can safely wear contact lenses varies depending on the type of lenses, the suitability of the material for your eyes, and how your eyes react to them. Understanding the recommended wear duration for different lens types is a good starting point:

Daily Wear Lenses

Daily wear lenses are designed for daytime use and must be removed before sleeping. Typically, these lenses can be worn for 8 to 16 hours, depending on the manufacturer’s guidelines and your optometrist’s advice. 

Removing them at the end of the day allows your eyes to rest and rehydrate.

Extended Wear Lenses

Extended wear lenses are made from materials that allow higher levels of oxygen to reach the cornea, enabling them to be worn overnight. However, not everyone is a candidate for extended wear lenses, so always consult your optometrist before considering this option. While some lenses are approved for continuous wear for up to 6 nights—or even up to 30 days for certain brands—it is crucial to follow professional advice to minimise risks like infection or corneal oedema.

Disposable Lenses

Disposable lenses are replaced after a specific period. Daily disposables are discarded after one use, while weekly or monthly lenses are replaced after 7 or 30 days, respectively. The convenience of daily disposables is unmatched—no cleaning routine is required, making them ideal for those with busy schedules or minimal time for lens maintenance.

Factors Influencing Wear Duration

Your ability to safely wear contact lenses for extended periods depends on several factors:

• Material and Breathability: Lenses made from silicone hydrogel allow more oxygen to reach the cornea, enabling longer wear times.
• Eye Health: Individuals with dry eyes, allergies, or certain medical conditions may need to adjust their wear time.
• Environment: Dry or dusty conditions can leave your eyes feeling irritated, reducing the comfortable duration for lens wear.
• Lifestyle: Activities such as swimming, exercising, or working long hours in front of a computer can also influence wear time.

Choosing the right type of lens for your lifestyle and following guidelines is essential to protect your eyes.

Signs of Overwear or Incorrect Use

Ignoring the recommended wear duration or misusing your contacts can result in discomfort or health issues. Be on the lookout for the following symptoms that may indicate overwear or incorrect usage:

• Redness or Irritation: If your eyes look bloodshot or feel uncomfortable, it could be time to take the lenses out.
• Blurred Vision: Cloudy or blurry vision can signal a buildup of debris or inadequate oxygen supply to the cornea.
• Dryness: Persistent dryness, even after applying rewetting drops, may indicate overwear.
• Pain or Swelling: Pain, sensitivity to light, or swelling of the eyelid should never be ignored—remove your lenses and seek medical advice immediately.
• Frequent Eye Infections: Recurring infections are a clear sign of improper lens hygiene or wear habits.

Listening to your body and addressing these signs early can help prevent more serious complications.

Best Practices for Safe and Healthy Contact Lens Use

Proper lens care and good habits are your best allies in maintaining healthy eyes. Here are some tips to ensure safe and effective lens use:

1. Follow Your Optometrist’s Recommendations

Your optometrist knows your unique eye health needs and will provide guidance on the most suitable type of lenses and their recommended wear times.

2. Maintain Proper Hygiene

• Wash and dry your hands thoroughly before handling lenses.
• Use the cleaning solution recommended by your optometrist—never water or saliva.
• Replace your lens case every 1 to 3 months to reduce the risk of bacteria buildup.

3. Stick to the Replacement Schedule

Adhering to the suggested replacement interval is crucial to avoid contamination. Even if lenses feel “fine,” overextending their use can compromise eye health.

4. Avoid Sleeping in Contacts (Unless Approved)

Unless you are using optometrist-approved extended wear lenses, always remove your contacts before sleeping to prevent complications such as corneal hypoxia.

5. Regular Eye Exams

Schedule annual eye exams to monitor your eye health and adjust your lens prescription as needed. Your optometrist can also detect any potential problems early on.

6. Use Eye Drops Mindfully

If you have dry eyes, opt for preservative-free lubricating drops that are safe for contact lenses. Avoid using other eye drops unless recommended by your doctor.

The Risks of Overwear and Non-Compliance

Non-compliance—whether it’s overwearing lenses or skipping proper cleaning routines—can lead to serious complications, including:

• Corneal Ulcers: Open sores on the cornea can cause pain, reduce vision, and even result in permanent damage if left untreated.
• Conjunctivitis: Also known as pink eye, it can occur due to dirty lenses or improper hygiene.
• Keratitis: An inflammation of the cornea, often caused by infection or oxygen deprivation.
• Corneal Neovascularization: Reduced oxygen supply can cause new blood vessels to grow in the cornea, potentially affecting vision.

Remember, prevention is always better than cure. By following best practices and paying attention to your eyes, you can reduce the risks significantly.

Prioritise Your Eye Health

Wearing contact lenses is a lifestyle choice that offers unmatched convenience and flexibility. However, it comes with responsibilities. By understanding the safe duration for lens wear and practising proper care, you can protect your vision and avoid unnecessary complications.
