If you use it 8 hours a day you probably have to adjust a bit to normal accommodation and convergence again instead of ignoring stereographic distance cues and always focusing in the distance. I doubt that will take longer than adjusting to a sudden increase in brightness.
Staring at stereograms, making my own software to create them including a 3D interactive landscape to fly through magic carpet style only enhanced my ability to see stereograms everywhere, even just looking at a keyboard. My eyes still work fine, apart from wearing glasses since I was 6.
