Is it a Bad Idea to Share Contact Lenses?

Sharing is caring—but sometimes it might not be such a good idea to share things. So should you share your prescription or cosmetic contact lenses? Like many other medical devices, the answer is a resounding no. For instance, when you purchase Acuvue Oasys 24 pack from, the contact lenses are specifically suited for your eyes and your eyes only, so sharing them with someone else could have harmful results. Anything from eye irritation to permanent vision impairment and blindness could occur just from simply sharing lenses with others. No matter the situation, it’s not worth putting yourself at risk.

One important reason why you should avoid sharing contact lenses is due to bacteria. Bacteria’s usually associated with negative connotation—especially from germophobes—but there is such a thing as good bacteria that are natural to your body. While your “good” bacteria may not harmful for you, it can be damaging to others and lead to infection if their eye tissue is exposed to foreign bacteria that have not been conditioned for their body.


Abrasions can also occur from sharing contact lenses whether they are prescription or cosmetic. As mentioned before, both prescription and cosmetic lenses are tailored for an individual eye, so if you’re wearing someone else’s lens the constant friction could scratch your eye. Telltale signs of potential abrasions are vision impairment and redness caused by irritation. While blurred vision may not seem like a serious problem initially, it can cause long-term damage—especially in the case of prescribed lenses.The prescription of the shared contact that isn’t prescribed to your own set of eyes can cause unnecessary strain on your eye, hence do not share your contact lens.


Besides infection, another potential danger is triggering an allergic reaction. For every responsible contact lens wearer, healthy cleaning habits play a major role in the daily maintenance routine. Within this routine, using the right contact solution is essential. Because this is a critical part of the hygiene of your lens, you should always use the solution that is recommended by your eye doctor as they are basing this recommendation off of any known allergies. So if you were to share a contact lens with someone, there is the potential risk that they are using a different solution brand from yours which could then result in an allergic reaction.

As you can see, sharing contact lenses should be avoided due to all of the potential dangers. When in the moment it may seem like a quick fix, but it can cause irritation, infection, and at times, irreversible damage. Instead of relying on a friend’s lens, just be sure to carry a pair of glasses in case a lens falls out. It’s a much safer alternative until you are able to insert new lenses, and could save you an emergency trip to your eye doctor.
