Yes I use the Tobii Eye Tracker 5 and it works great even with glasses. Until there are more configuration options inside of MSFS(please add your vote here: Tobii Eye Tracking needs configuration options) you can use FaceTrackNoIR to get 6DOF and tweak sensitivities.
There are also plenty of other people who use Tobii Eye Tracker:
