The SDSS survey is uncovering many gravitationally lensed quasars and
demonstrating the usefulness of large-scale optical surveys for
lens statistics. In the SDSS, lensed quasars are surveyed by searching
''extended'' quasars for small-splitting lenses, or by comparing colors of
stellar objects nearby quasars if lensed images are well resolved.
Although LSST data have no spectroscopic information, its multi-epoch
multiwavelength imaging observation makes it possible to conduct an
efficient search of lensed quasars by making use of their colors and time
variability. We will discuss the propsect for finding lensed quasars from
LSST and for determining cosmological parameters.
