First, a disclaimer. Do not do what I'm about to tell you, but this has worked for me for well over 20 years. I have been wearing Accu-Vue and then Accu-Vue 2 lenses for about that long and have found that I can go between 2-3 months wearing mine, 24/7, before I even start to notice that I have them on. I rarely, if ever, use lens lubricant or even saline. I am careful not to rub my eyes hard first thing in the morning, but other than that, no other precautions have been necessary. I have annual eye exams and have never had any problems. Again, this works for me and is not recommended.
