I have night and day contact lenses ( you can sleep in them) and so far I've done just that. To be honest, I don't take them out until either my eye hurts because something got in it or until they need to be changed.
My dad is worried that my contacts will grow into my eye and won't be able to be taken out. Is this true? And how long does that take?
I usually change contacts every month or 2 ( 2.5 months has been the max I believe. Maybe less)
