1. A method of providing modified monovision to a subject with a first lens and a second lens, comprising:
implanting the first lens into a first eye of the subject, the first lens configured with a first extended depth of field,
wherein anterior and posterior surfaces of an optic of the first lens are shaped to provide average modulation transfer function (MTF) values that are between 0.1 and 0.4 at 100 lines per millimeter for at least 90% of the object vergences within the range of 0 to 2.0 D or 0 to 2.5 D when the optic of the first lens is inserted into a model eye having an aperture size from 4 to 6 millimeters, wherein the average MTF values of the first lens comprise MTF values at 100 lines per millimeter integrated over the wavelengths between about 400 to 700 nm weighted by the photopic luminosity function for on axis objects; and
implanting the second lens into a second eye of the subject, the second lens configured with a second extended depth of field,
wherein anterior and posterior surfaces of an optic of the second lens are shaped to provide average modulation transfer function (MTF) values that are between 0.1 and 0.4 at 100 lines per millimeter for at least 90% of the object vergences within the range of −2.0 to 0 D or −2.5 to 0 D when the optic of the second lens is inserted into a model eye having an aperture size from 4 to 6 millimeters, wherein the average MTF values of the second lens comprise MTF values at 100 lines per millimeter integrated over the wavelengths between about 400 to 700 nm weighted by the photopic luminosity function for on axis objects,
the second eye different than the first eye,
wherein implanting the first lens with the first extended depth of field provides the subject an extended depth of field in the direction of nearer objects, and
wherein implanting the second lens with the second extended depth of field provides the subject an extended depth of field in the direction of more distant objects.
