Contact lenses that correct your vision during the night?

So I have a friend, whose sister has had these sorts of contacts… You wear them during the night and take them off in the morning, (but you don't wear glasses or anything to correct your vision during the day) and then as you continue to do this every single night, for a certain period of time, your eyesight eventually gets better and better, until you have 20/20 vision naturally during the day and whenever.So now, my questions are:
1) can anyone who has myopia with any strength of prescription( mine is -4.5 on both eyes) talk to their optometrist about it and get these contact lenses?
2) are these contact lenses reliable?
3) around how much do these lenses cost?
4) how long does it take for these lenses to eventually bring your vision back to 20/20 vision, and do you still have to continue wearing them even after your vision is corrected?
5) are these lenses a better option than wearing your regular monthly disposable contact lenses/ extended wear lenses? If so, what's the reason many people don't choose to wear them? (Or not that I know of many who do anyway..)

Thanks heaps in advance guys! :D
