Clear aligners deal with an open bite very well. The thickness of the aligner material between the teeth has an additional effect of gently pressing the back teeth in (intrusion), which helps to correct an open bite. In the front or side teeth, where the tongue sometimes pushes in between the teeth and contributes to the open bite, the aligner acts as a barrier for the tongue and helps the problem resolve more easily.
This answer is for general information. Your own case needs an examination by an orthodontist.
