1. Any tips on putting them in? I get them in some mornings with little trouble. Other days I just can't do it.
2. I can't tell inside out from the right way out. To me they look the same. Any clues?
3. I have been told that they should last "about 2 weeks". How can I tell when I need to throw a lens away?
