There’s a good chance you’re not looking at that for a couple of reasons: It’s just a bunch of numbers in too small a package, you’re not clear why it matters, or the dates are generally so far away that users contact lenses regularly, they use them well before the expiration date. But while the reasons aren’t clear, obeying the expiration date is an important part of keeping your eyes safe and healthy.
You should pay close attention to the expiration date of your contact lenses. They are medical devices that must be sterilized and stored in hermetic containers before being used because they are in direct contact with the eye. If the lens is contaminated, there is a high probability of causing an infection.
Contact lenses are sealed in an airtight container which is designed to protect and keep the lens in optimal condition.
The dates indicated on the packaging have their raison d’etre. After this date, the container may be affected, causing contamination of the saline solution and therefore increasing the risk of eye infection if you use them.
Information that you should find on the packaging of your contact lenses:
- Brand
- Material name
- Manufacturer name
- lens base curve
- Diameter
- lot number
- Expiration date
It is common for the expiration date on your soft contact lenses to be 4 years from the date of manufacture and is usually written on the bottom of the package, in a yyyy/mm format.
Don’t forget to check the date every time you open a new container. Do not unnecessarily expose yourself to any danger!
