Contact lenses have come a long way in the last few decades. With the advent and development of soft lenses, you can comfortably wear your contacts for extended periods of time. However, you might want to rethink your “extended wear” habits. Practicing good hygiene and taking your contacts out when you go to sleep could save your vision.
You might think that rinsing your contacts out in tap water or leaving them in when you take a nap or even overnight isn’t a big deal, but you’d be wrong. Just a few months ago, a student in Taiwan permanently lost her vision when amoebas burrowed through her corneas. What caused this amoebic infection? The student did not take out her contacts -- which were disposable and only made to be worn for 1 month -- for 6 months straight.
Now, this is an extreme case. Very few people leave their contacts in for this long. Most of us take them out at night most of the time, and we usually take them out when we go swimming, too. However, you shouldn’t brush this shocking story off and think, “That could never happen to me.” You might be guilty of some poor hygiene habits that could result in an eye infection or vision loss.
