Recently, multifocal lenses are being used by some people with various degrees of presbyopia. Their meridional distribution of optical power may produce a distortion which has a counterpart in the estimate of the visual field.
Data recorded by us, on a number of skilled and cooperative individuals reveal an isopter constriction as well as a loss in peripheral vernier acuity.
