You asked

Are there any contact lenses which I can sleep in?

Yes, there are extended wear contact lenses which you can wear continuously for up to 30 days without taking them out. After the 30 days, they are taken out and replaced with new contact lenses. The amount of time you can leave them in for will vary depending on the brand. Extended wear contacts let you start your day with clear vision. They are made from special materials which allow more oxygen to reach your eye, which makes them safer to sleep in.
You should make an appointment with your optician who will advise you whether extended wear contact lenses are suitable for you.
