If you have contact eye care solution, of course, it is best to use contact eye care solution to soak your contact lenses. But if there is really no care solution, you can use pure water, a clean liquid, if you really can not get pure water, mineral water can also be. It’s best not to use tap water, a source of water that you can’t be sure is clean. If you take unclean water and wear it inside your eyes, it may cause conjunctivitis and keratitis, so you need to pay attention to this aspect as well. In addition to using ordinary liquids, you can also use eye drops to soak. In general anti-inflammatory eye drops or eye drops that moisturize the eyes can be used to soak contact lenses, so it depends on the individual’s choice.
