Is it alright to sleep with my contacts in my eyes?

To take a nap for let's say half an hour is not a medical issue regardless which lens ýou use, but it could feel a bit dry in your eyes when you wake up again. If you wish to sleep a whole night with your lenses you must have a certain type of lens that is designed for that kind of use. You should also consult your optometrist before you start to sleep with your lenses.
