Computer Vision Syndrome: A Problem of The Digital Age
Generally, most man-made products come with an expiration date, and so does contact lenses. You will find the expiry date mentioned on every individual lens package. However, there’s a high possibility that you rarely ever look at the date as it may seem like just a few tiny bars and numbers on a small package – this is where you find the expiry date.
But why do contact lenses have an expiration date? Can you use expired contact lenses? What to do if you have used expired contact lenses? Don’t worry; this article will help you understand the essential things about contact lenses expiration dates.
Why Do Contact Lenses Have An Expiration Date?
It is important to note that the contact lenses themselves don’t have an expiration date. It is typically the saline solution present in the blister pack that expires. While the contact lenses get manufactured, every lens first goes through sterilization before they are packed into air-tight blister packs with saline solution in it. Predominantly, the maximum duration that the saline solution and the packaging can preserve its condition falls between one to four years after the date of manufacturing.
Beyond the expiration date, the saline solution’s active ingredients start to deteriorate and lose its form, Moreover, a general assumption is made during the manufacturing, which considers the probability that the blister seal might lose its grip and let air or bacteria through. This might result in lens contamination, which can cause blurry vision, eye infections, and irritations, and in some cases, leads to severe implications.
In case the seal of the contact lenses’ blister pack is broken, it becomes easy for air to seep into the pack and contaminate the saline solution, which infects the lens and, thus, your eyes. The seal gaps can be so tiny that you might not notice it; therefore, it is crucial to stick to the expiration date mentioned on the contact lenses package. It is important to note that you will find expiration details of all kinds of disposable contact lenses – daily contact lenses, monthly, bi-weekly, half-yearly, and yearly contact lenses as well.
Note: This happens and applies to all types of contact lenses, including disposable contact lenses such as:
- Daily Contact lenses
- Monthly Contact Lenses
- Yearly Contact lenses
- Colored Contact lenses
What To Do If You Accidentally Have Used Expired Contact Lenses?
Have you worn a pair of expired contact lenses by mistake? If so, refrain from panicking.
when you find out that your lenses are expired, the first thing to do is remove them from your eyes and discard them. If you feel any irritation – even mild one, immediately visit your optometrist and get an eye examination. Your eye care specialist can help check your eyes and recommend appropriate treatment if needed.
You must remember that failing to adhere to the lens wear and care instructions, including the practice of wearing expired contact lenses, be it daily contact lenses, monthly or yearly contact lenses, can give rise to eye infections and other eye conditions.
To avoid any such eye problems, you must talk to your eye care specialist about the product details before purchasing any contact lenses. During the purchase – always remember first to check the expiration date of the contact lenses.
How To Find The Expiration Date Of The Contact Lenses?
Typically, the product details, including ingredients, standards, price, manufacturing, and the expiration of any contact lenses, can be found in two places – the packaging box and the lens blister pack. You will probably find it next or below the manufacturing date and lot number. The date may be mentioned in one of the two ways mentioned below:
- YYYY-MM — 2024-08 — August 2024
Do Contact Lens Care Solutions Expire?
Yes, even contact lens care solutions have an expiry date. After the lens care solution’s expiration, the acidity level of the solution changes, leading to the loss of its disinfecting power. The expired lens care solution might also be contaminated with bacteria, which further risks your eyes’ safety and health.
The expiration date is generally listed on the label, which can be found printed anywhere on the bottle’s packaging. Since lens care solutions are typically available in large bottles, you will be using a bottle for an extended period; thus, you need to ensure that you don’t use it beyond its expiry date. Similarly, your contact lenses, too, must not be worn post the expiration date mentioned on the product packaging. Suppose you notice that your lens care solution has expired. In that case, you must immediately discard the bottle and consult with your eye care specialist to buy the best contact lenses’ care solution.

What does 'Shelf Life' of Sterile Implantable Orthopaedic Devices mean?
Dear Sir,
When we talk about "shelf life" of sterile implantable medical devices, does it means the expiry date of sterilization or how long the device can serve its intended purpose in human body? Hope to learn from you.
Thank you.

Dear Sir,
If i understand correctly, what you means is the shelf life not only the sterilization expiry date (before implant), but also the time where the implantable device stays in the human body (after implanted), correct?
Thank you.

Shelf life relates not only to maintaining sterility, but to deterioration in the quality of the device as well. Shelf life ends when the device is either put into use; discarded; or deteriorates to a point where it no longer conforms with its specification.
Sterilization pouches and expiry dates
Unless indicated by the manufacturer, there are no expiry dates on pouches.
A lot number and the date of manufacture are printed on the boxes.
The date of manufacture is in the form of year month day.
- example 180410.
Expiry dates are typically linked to a food or chemical registered with Health Canada.
What if there’s no expiration date on sterilization pouches?
If the pouch has been processed, the integrity has not been compromised and the manufacturer does not have an expiration date on the box or in the manufacturer’s instructions, then sterility is fully maintained.
Some offices follow their own policy of one year from the date of processing, but that is up to the individual office.
If the integrity of the packaging has been compromised such as being ripped or wet, or the manufacturer includes an expiry date that has passed, the items must be reprocessed as they are no longer considered sterile.
«For items reprocessed in the clinical office, if the integrity of the package has been maintained, the item remains sterile. A plastic dust jacket may greatly extend the shelf life of the package and should be used on muslin or crepe wrapped packs. If a sterile tray/package has been purchased and has an expiry date/label, follow the manufacturer’s recommendations and discard when outdated.»
The following is from Public Health Ontario- Best Practices for Cleaning, Disinfection and Sterilization in All Health Care Settings 3rd edition May 2013 page 52-3:
Maintaining sterility also includes the rotation of stock, where the oldest stock is used first.

По поводу чипирования
А у меня проблема вот какая. Недавно по моему заказу чипировали моего кота; вместе с сертификатом на чип мне дали несколько наклеек, под последней из которых значится: "Sterilization expiry date:" (далее указаны месяц и год, примерно как на лекарствах — "Годен до:" и тоже месяц и год). Что это значит? После данного (указанного под наклейками) месяца чип станет недействительным, или его просто надо было успеть имплантировать не позже "этого" месяца? Всё-таки после "этого" месяца лекарство (даже уже начатое, но "недопитое") принято выбрасывать, гальванический элемент ("батарейку") — нет (просто надо до "этого" месяца начать использовать); а как с чипом? Надо ли после окончания указанного месяца чипировать зверя заново?
