There’s nothing like a permanent contact lens, there always a limit to how long it can stay on the eye, we have daily disposable one and reuseabke ones, whichever it may be at the end of the day you will have to take it out of ur eye and keep it in its solution of throw it away.

As I mentioned in the writeup, frequent wearers are likely to suffer from reduced cornea sensitivity and are more prone to keratitis infection especially when they CL is not kept well, however should you follow the instructions of you OD accordingly you should be fine
