  We present an estimation of the expected number of arcs and arclets in a
sample of nearby (z<0.1) clusters of galaxies, that takes into account the
magnitude limit of the objects as well as seeing effects. We show that strong
lensing effects are not common, but also they are not as rare as usually
stated. Indeed, for a given cluster, they present a strong dependence with the
magnitude limit adopted in the analysis and the seeing of the observations. We
also describe the procedures and results of a search for lensing effects in a
sample of 33 clusters spanning the redshift range of 0.014 to 0.076,
representative of the local cluster distribution. This search produced two arc
candidates. The first one is in A3408 (z=0.042), the same arc previously
discovered by Campusano & Hardy (1996), with z=0.073 and associated to the
brightest cluster galaxy. The second candidate is in the cluster A3266
(z=0.059) and is near a bright elliptical outside the cluster center, requiring
the presence of a very massive sub-structure around this galaxy to be produced
by gravitational lensing.
