We present optical photometric and spectroscopic observations of twoCataclysmic Variables (CVs), namely RBS 0490 and SDSS J075939.79+191417.3. Theoptical variations of RBS 0490 have been found to occur at the period of1.689$\pm$0.001 hr which appears to be a probable orbital period of the system.Present photometric observations of SDSS J075939.79+191417.3 confirm and refinethe previously determined orbital period as 3.14240928$\pm$0.96 hr. Thepresence of long-duration eclipse features in the light curves of SDSSJ075939.79+191417.3 indicates eclipses might be due to an accretion disc andbright spot. The orbital inclination of SDSS J075939.79+191417.3 is estimatedto be $\sim$ 78 $^\circ$ using the eclipse morphology. The phased-light curvevariations during the orbital cycle of RBS 0490 provide evidence of theemission from an independent second accretion region or a second fainter pole.Optical spectra of RBS 0490 and SDSS J075939.79+191417.3 show the presence ofstrong Balmer, weak He II ($\lambda$4686) emission lines, along with thedetection of strong $H\beta$ emission lines with a large value of equivalentwidth. The characteristic features of RBS 0490 seem to favour low-field polars,while SDSS J075939.79+191417.3 appears to be similar to the non-magneticsystems.
