Have you ever wondered if your contact lenses have expired but don't look broken, can you continue to wear them? Now, let's explore this question and find out the right answer.
First of all, we need to understand what it means that contact lenses are expired. The shelf life of a contact lens is usually the length of time it retains its performance and hygiene standards under normal use and storage conditions. After the expiration date, the performance of contact lenses may change and hygiene standards may deteriorate, which may have an impact on eye health.
Although your contact lens does not appear to be broken, after the expiration date, it may have accumulated a large amount of protein and bacteria that are not visible to the naked eye. These proteins and bacteria can cause eye infections and, in severe cases, even affect vision.
For example, even if the mask we usually use does not look damaged, after a period of time, the filtering effect of the mask will be reduced, and it will not be able to effectively block bacteria and viruses. Similarly, even if contact lenses do not appear to be damaged after they expire, their performance and hygiene standards may no longer meet our needs.
So, how to use and store contact lenses correctly to prolong their lifespan? First of all, we should follow the doctor's advice, check our eyes regularly, and replace our contact lenses in time. Secondly, we need to keep our contact lenses clean to avoid the accumulation of proteins and bacteria. Finally, we need to store our contact lenses properly and avoid direct sunlight and high temperatures.
