Well, in my opinion, you’d better not reuse disposable contact lenses, or it can lead eye infections, especially the pink eyes. As we know that some one-day contacts are hydrophilic contacts and are not intended on being used for more than 8 hours of continuous wearing time. So if you reuse them, they can be harm to your eyes, for they are not designed to hold up to multiple wears, repel particles. And what is more, they are not stored in the solution, so they can be invaded by the bacteria. And when you reuse them and have no cleaning, it can make your eyes be infected. In some serious cases, it can lead to pink eyes, bloodshot eyes. Anyway, you should not reuse them.
