For ease of discussion, the terms “Presbyopia” and “pre-Presbyopia” will be referred to hereinafter as simply “Presbyopia”. The invention is directed to a lens series comprising lenses that are tailored to provide an amount of positive ADD power in the central optical zone that is tuned to the residual accommodation and the dynamics of the individual's visual system and to provide an amount of negative spherical aberration in the peripheral optical zone. As an eye accommodates for a near vergence, the pupil constricts (myosis) and the spherical aberration of the optical system becomes more negative. These dynamic ocular factors act to increase the depth of focus of the individual's visual system. In essence, these dynamic ocular factors work in conjunction with the positive ADD power provided by the central optical zone o...
