When it comes to your eyes, safety should always come first. You likely follow the instructions of your eye doctor carefully, cleaning and maintaining your contact lenses as prescribed. But what happens when you come across a batch of expired contact lenses? Is it okay to continue wearing them past their expiration date? Let’s explore the risks and reasons why it’s not a good idea to use old contact lenses.
Why Expired Contact Lenses Are Dangerous
Wearing expired contact lenses or using them beyond their prescribed wear time can be harmful to your eyes. Over time, contact lenses lose their effectiveness and safety features, raising the risk of eye irritation, infections, and corneal abrasions. If you’re thinking about wearing expired contacts, it’s best to reconsider. Discomfort and irritation are signs that it’s time to replace your lenses with a new pair.
The Risk of Bacteria on Expired Lenses
One of the primary reasons contact lenses have expiration dates is to prevent bacteria from accumulating on the lenses. Contact lenses can absorb bacteria, dust, and allergens, which can multiply over time and lead to serious eye infections. Expired contact lenses act like a sponge, soaking up more bacteria and potentially leading to corneal ulcers, which can result in permanent vision damage.
Oxygen Flow and Expired Contact Lenses
Another issue with expired contacts is that they become less permeable over time. This reduces the amount of oxygen that can flow properly to your eyes. Without sufficient oxygen, your eyes can become red, irritated, and swollen. If you’re experiencing these symptoms while wearing expired contact lenses, it’s important to replace them immediately to avoid further discomfort and potential damage to your eyes.
Frequently Asked Questions About Expired Contact Lenses
Q: How long do contacts last before they expire?
A: Contact lenses typically expire 4-5 years after packaging. However, it’s essential to have regular eye exams for contact lenses to ensure your prescription remains accurate and your lenses continue to meet your visual needs.
Q: Do contact lenses expire?
A: Yes, contact lenses expire because the saline solution that protects them can become ineffective after the expiration date. The solution can turn more acidic or alkaline, which can damage the lens and affect its performance.
