Technical Field

Background

Medical science today admits: the growth of the eyeball of the myopia of the teenagers depends on the regulation of the peripheral defocus of the retina, the peripheral hyperopic defocus of the retina promotes the growth of the eyeball, the peripheral hyperopic defocus of the retina is corrected, and the growth of the myopia eyeball can be controlled.

Vision CRV ltd, filed for patent name: lenses for myopia correction, chinese patent No.: 2006800441239 which discloses peripheral out-of-focus spectacle lenses with a perfect circle in the central zone and a full ring-shaped positive addition in the peripheral zone.

Calzaisi Vision AustraliaStock control, ltd, application for patent name: ophthalmic lens element, chinese patent No.: 2008801159183 discloses peripheral defocused spectacle lens with transverse oval central zone and full-ring positive addition peripheral zone, and the product is named as Chuasi Changle

Smith EL is a peripheral defocus theory creater and a peripheral defocus spectacle lens pioneer, smith in the latest research paper thereof critically points out that the original design of a treatment area in a 360-degree area around a spectacle lens has design defects, and a half-concave lens sheet rhesus experiment is used, so that the result is that the temporal retina dominates the growth of an eyeball, and the peripheral hyperopic defocus inducing the growth of the eyeball is a Local and regional Selective mechanism Local and regional. Temporal retinal dominant eyeball growth, nasal temporal retinal peripheral defocus exhibiting asymmetry, annular correction not eliminating peripheral refractive error, and also generating new peripheral refractive error hyperopic anisometripidi, see literature: smith EL: optom Vis Sci,2013, 90:1176-1186; smith EL: invest Ophthalmol Vis Sci,2010, 51:3864-3873; smith EL: invest Ophthalmol, vis Sci,2009, nov;50 (11): 5057-5069. Smith also describes in WO2012/012826A1, WO2013/134825A1 that for 1155 cases of myopic eye retinal peripheral refraction tests with myopic power of-2.27D ± 0.83D, 40 ° temporal side is greater than nasal peripheral refraction mean +0.83D.

The applicant confirms that the larger the myopic eye power is, the larger the hyperopic defocus of retina periphery at 40 degrees on the temporal side is, the larger the hyperopic refractive power difference value of retina periphery at the nasal temporal side is, and the individual maximum refractive power difference value is larger than +1.50D on 1809 myopic eye retina periphery refractive tests.

The conventional refraction type peripheral out-of-focus spectacle lenses have the defects that the peripheral treatment area uses the equivalent positive value, the hyperopic anisometropia at the periphery of the nasal temporal retina cannot be corrected or eliminated, and the correction of the hyperopic anisometropia at the periphery of the nasal temporal retina has more scientific significance for preventing and controlling the myopia.
