Long term optical and near-infrared photometric and blue spectroscopic observations were obtained for QS Tel , V834 Cen , and BL Hyi .
The optical light curves of all three polars displayed large magnitude changes during our observations .
These same high/low state transitions were also apparent in near-infrared JHK photometry , though with decreased amplitude .
The color of the polar with respect to its state was examined and found not to be a good indicator of the instantaneous state .
During low to high state transitions , a nearly constant magnitude difference was observed in all three polars .
This \Delta m value was found to be consistent with the level expected to occur if accretion onto the white dwarf reached the Eddington luminosity during the high state .
The high state Balmer decrement was measured for each star and used to estimate that the temperature of the emission line forming region was \sim 12,000K with N _ { H } near 12.8 dex .
No relationship between the Balmer emission line strength and the white dwarf magnetic field strength was seen , in contrast to a good correlation between these two parameters observed for UV emission lines .
