Not all contact lenses are meant to last the same length of time, and wearing them too long can put your eye health at risk. From daily disposables to monthly wear, understanding how long your lenses are designed to last is key to staying comfortable and seeing clearly.
Daily lenses last for one day, biweekly lenses for up to 14 days, and monthly lenses for 30 days from first use. It’s important to respect these different lifespans. You shouldn’t ever wear lenses longer than recommended. Always follow good eye health habits to help keep your vision safe and sharp.
Why Contact Lens Lifespan Control?
Wearing contact lenses beyond their recommended lifespan can lead to issues like discomfort, dryness, irritation, or even eye infections. By sticking to your lens replacement schedule, you can protect your eyes from unnecessary risks and promote improved vision through your lenses. Each type of contact lens is designed with a specific lifespan in mind.
Types of Prescription Contact Lenses & Their Lifespan
Daily Disposable Contact Lenses
Daily disposable lenses are recommended for those who value convenience and hygiene. These lenses are designed for single-use, meaning you wear them once and then throw them away. They reduce the need for cleaning and storage, making them the most low-maintenance option.
- Ideal for: Busy individuals or people prone to allergies, as they minimize exposure to allergens.
- Lifespan: One day. Always replace these lenses after each use, even if you only wore them for a few hours.
Biweekly Disposable Lenses
Biweekly lenses are designed to be worn daily and replaced every two weeks. These lenses require proper cleaning and storage to maintain their integrity and safety throughout the two-week period.
- Ideal for: People who want a balance between convenience and cost-effectiveness.
- Lifespan: Up to 14 days when cleaned and stored properly each day. Skipping these maintenance steps can lead to discomfort or potential eye health issues.
Monthly Reusable Contact Lenses
Monthly lenses offer flexibility. They’re a great option for regular contact lens wearers. With proper care, a single pair can last up to 30 days.
- Ideal for: Frequent wearers who are diligent about lens care routines.
- Lifespan: Up to 30 days. However, extended-wear lenses (those approved for overnight use by an eye doctor) should still be disinfected regularly according to your optometrist’s recommendations.
Extended-Wear Lenses
Extended-wear lenses are designed to be worn continuously for 7–30 days. They’re made from materials that allow extra oxygen to reach your eyes.
- Ideal for: Those with specific conditions approved by an eye doctor. Extended wear requires close monitoring by your optometrist.
- Lifespan: Follow your optometrist’s guidelines closely, as these lenses come with a higher risk of infection if worn for too long.
Why You Shouldn’t Extend Lens Wear Beyond Guidance
Here are several reasons why you shouldn’t extend the lifespan of your contact lenses:
- Irritation and discomfort: Protein and lipid deposits can build up on the lenses over time, causing discomfort and blurry vision.
- Eye health risks: Old lenses can harbor bacteria, increasing the risk of infections like keratitis.
- Reduced effectiveness: The integrity of the lens materials deteriorates over time, impacting the comfort and clarity they provide.
If replacement times feel confusing, don’t hesitate to speak with your eye care professional to clarify any concerns.
Additional Tips for Proper Contact Lens Care
To extend the safe use and effectiveness of your contact lenses, consider following these care tips:
Clean & Store Them Properly
For reusable lenses, use a high-quality disinfecting solution and never rinse lenses with tap water. Always store them in a clean lens case filled with fresh solution to prevent contamination. Replace your lens case every 1–3 months.
Wash Your Hands
Before handling your lenses, thoroughly wash and dry your hands. This reduces the risk of transferring dirt or bacteria to your eyes.
Follow Your Wear Schedule
Stick to your optometrist’s instructions for how many hours a day you should wear your lenses, and avoid sleeping in them unless advised otherwise.
Keep Up With Regular Eye Appointments
Routine check-ups with your optometrist are critical for monitoring your eye health and helping ensure that your contact lens prescription is accurate.
Knowing When to Replace Your Contact Lenses
The lifespan of contact lenses also depends on how often you wear them. Even if you only wear them sporadically, you should still stick to their replacement schedule. For example, if your monthly lenses sit unopened but have been used for the first time on January 1, they should still be replaced by January 31, whether you wore them every day or not.
