Contact lenses are a game-changer for those needing vision correction. They bring comfort and convenience over traditional glasses, making them extremely popular. But there’s one detail some people overlook—expiration dates.
All contact lenses expire, and ignoring the expiration date could put your eyes at risk. Using contacts beyond this date can decrease their effectiveness and lead to unnecessary risks, such as eye infections, scratches, and more.
If your lenses have expired, visit our eye doctors at CHROMA for a contact lens fitting and exam. Don’t put your eyes at risk.
How Long Do Contact Lenses Stay Safe to Use?
Every box or blister pack of contact lenses you buy has a small printed expiration date. This date isn’t arbitrary, and it shouldn’t be ignored. It’s based on how long the manufacturer can guarantee the lenses will remain safe and effective.
Typically, contact lenses expire 1–4 years after production. After the date passes, lenses may degrade in quality or lose their sterility. Even if they look fine, expired lenses can present real risks, like introducing bacteria into your eyes or irritating your corneas. Pay attention to that tiny number—it’s there for your benefit.
Why Do Contact Lenses Expire?
The lifespan of your lenses comes down to the materials they’re made from and the way they’re stored. Proper maintenance goes a long way.
First, the materials in lenses and the accompanying solution can deteriorate over time. This can weaken their ability to stay sterile and maintain their shape. Improper storage—like leaving them in sunlight or extreme temperatures—can speed up this process even further.
Then, the lens type matters as well. Soft lenses, rigid gas-permeable lenses, and extended-wear contacts all have varying shelf lives due to their distinct material compositions.
It’s important to remember that contact lenses are medical devices. Staying within the recommended time frames keeps them safe to use, and significantly reduces the risk of eye problems.
Health Risks of Using Expired Contact Lenses
Expired lenses can become fertile ground for bacteria, leading to infections that may cause redness, irritation, and discomfort. Over time, the degraded material in these lenses may lose their smoothness or integrity, reducing your quality of vision or even scratching your eyes.
Expired lenses increase the risk of:
- Eye infections, such as conjunctivitis or keratitis
- Corneal ulcers, which can lead to long-term damage if untreated
- Blurred or impaired vision due to compromised lens quality
- Allergic reactions stemming from degraded materials
- Severe discomfort and irritation during wear
Additionally, expired lenses aren’t as good at doing their job. Visibly worn or degraded lenses may not correct your vision as effectively, putting strain on your eyes.
Using expired lenses is more than just a gamble with comfort. It can lead to serious eye health concerns and expose your eyes to potential hazards.
Tips for Storing & Caring for Contact Lenses
Taking proper care of your lenses is essential. It’s another major step in keeping them safe and comfortable to use through their shelf life. Follow these foundational care tips to keep them in top condition:
- Always store your lenses in a clean case with fresh contact lens solution.
- Never rinse or soak your lenses in tap water—this introduces harmful contaminants.
- Clean your lens case often and replace it every 3 months.
- Keep lenses away from direct heat and sunlight, storing them in a cool, dry place.
- Follow the replacement schedule set by your manufacturer, even if your lenses still feel fine.
By treating your lenses with care, you extend their usability. You also protect your eyes from preventable risks, making this a core part of your routine.
What to Expect During a Contact Lens Exam
Regular appointments with the doctors at CHROMA are one of the easiest ways to make sure your prescription is up-to-date. These exams are opportunities to address potential concerns about your lenses and replace them as you get closer to the expiration date.
A contact lens exam typically begins with a review of your current prescription and a discussion about your lifestyle. We’ll measure your eyes carefully to make sure your future lenses fit. Then, we’ll provide guidance on the proper care routines based on the lens type you choose.
