Abstract:
1. A set, kit or stock of pre-manufactured lenses for use in the provision of an anti-myopia lens for an eye of a myopic patient, wherein: each lens of the set, kit or stock has a central optical axis and a central optical zone surrounding and including said axis, said central optical zone has a negative corrective refractive power between plano and −6.0 D, for correcting a positive central refractive error of a myopic eye, said negative corrective refractive power varying in increments of a central refractive power within said set of lenses, each lens has a peripheral optical zone surrounding said central zone, said peripheral zone includes an incident angle with respect to the optical axis of about 30 degrees, said peripheral zone of each lens has a positive peripheral refractive power relative to the refractive power of the central zone of that lens to thereby provide myopic peripheral defocus, said peripheral refractive power increases with increase of central refractive power within the set of lenses, said peripheral defocus of any lens within the set, kit or stock of lenses is not greater than about 3.5 D, and the lenses of the set, kit or stock are arranged in an orderly manner according to central refractive power, peripheral refractive power and/or peripheral defocus; whereby a clinician is enabled, by selecting a lens for corrective power to provide or procure a lens to inhibit progression of myopia in the patient's eye without needing to first measure peripheral refractive error in the eye and to order a lens with customized peripheral power.
