J Ophthalmol. After a long day of work and no play, you just want to go to bed. Or, worse yet, you leave your contacts in your eyes. Putting contacts in water and all the other things on the list we're giving you are huge no-nos. We tend to see water as a pure element, but water contains germs and other contaminants you don't want anywhere near your eyes. Most of the bacteria are harmless to the human body, but not all. If you're still not convinced, there's another germ that might change your mind.
Acanthamoeba is an amoeba commonly found in tap water, lakes, wells and other sources. It causes Acanthamoeba keratitis, a painful infection that can take years to treat and even cause blindness. In addition to the dangers of introducing bacteria to your eyes, you have the water's effect on your lenses to think about, too. Water warps and swells soft contact lenses. The transformation can scratch your cornea, creating an easy pathway for contaminants. One word: don't. We all know doctors can get a little overprotective sometimes, but this is one instance where you absolutely need to listen to them.
Contact lenses are made from plastic and impair oxygen flow to your cornea. This part of the eye the outer, clear covering has zilch in the blood flow department, so it relies on oxygen to remain healthy. If you cut off that oxygen say, when you close your eyes to sleep and there's a plastic cup over the cornea , things get a bit dicey.
Small blood vessels grow to compensate for the oxygen deprivation. This causes keratitis, or corneal inflammation. If untreated, it can lead to blindness. These are Health Canada approved and allow your eyes to breathe overnight. We know. Who really bothers to wash their hands every time? Isn't that what the cleaning solution is for? But as with the water discussion above, washing your hands is vital.
Soaking contacts in a saline solution overnight is dangerous because contamination may happen. However, using those comes with very serious risks. Making a DIY solution sounds easy and even economical.
But it's not recommended by eye care professionals. For the DIY solution to work properly, all the materials used must be completely sterile. This is absolutely essential and impossible to do at home. Having a sterile contact solution means your contacts stay clean from all contaminants.
If you've left your contact solution at home and can't get any more at the last minute, the best thing to do is throw the contacts out. Using anything else puts you at risk for significant eye damage. This can include blindness. It is also not recommended by professionals for storing your contacts.
Tap water contains bacteria and microorganisms. Once in your eyes, they can cause a rare disease called Acanthamoeba keratitis. Acanthamoeba keratitis is a very serious infection of the cornea.
It is extremely painful and could necessitate a corneal transplant. In the worst case scenario, blindness can occur.
