We present measurements of the polarized optical spectra of NaV2O5 and LiV2O5. In an energy range from 0.5 to 5.5 eV, we observe similar peaks in the E\ensuremath\Verta spectra of NaV2O5 and LiV2O5, which suggests similar electronic structures along the a axis in both materials. On the other hand, we find an almost complete suppression of the peaks in \ensuremathσb of LiV2O5 around 1 and 5 eV. We attribute this suppression to the charge localization effect originating from the existence of a double-chain charge-ordering pattern in LiV2O5.
