Smith, in its latest research papers, critically points out that it originally designed the treatment zone in the 360 ° peripheral region of the lens, has design defects, and proposes that peripheral hyperopic defocus inducing eyeball growth is a Local, regioselective mechanism, regional mechanism. Temporal retinal dominant eyeball growth, asymmetry in nasal-temporal peripheral defocus, failure of annular correction to eliminate peripheral refractive error, and generation of a 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 opthalmol, Vis Sci, 2009, Nov; 50(11): 5057-5069. Smith, in WO2012/012826a1, WO2013/134825a1, describes a 40 ° temporal greater than nasal peripheral refraction +0.83D for-2.27D ± 0.83D, 1155 cases of myopic eye retinal peripheral refraction test.
The applicant finds that for 1809 cases of myopia peripheral refraction detection: the higher the myopic degree is, the higher the hyperopic defocus of the retina periphery at the temporal side is 40 degrees, the higher the hyperopic refractive power difference value of the retina periphery at the nasal temporal side is, and the individual maximum refractive power difference value is larger than + 1.25D.
No matter the refractive or micro-lens type peripheral out-of-focus spectacle lenses, the peripheral treatment area uses the equal positive value, and the hyperopic refractive error around the nasal temporal retina cannot be corrected, so that the correction of the hyperopic refractive error around the nasal temporal retina has more scientific significance for preventing and controlling the myopia.
The peripheral out-of-focus spectacle lens is to be developed into a new surface type innovative design, and the peripheral out-of-focus spectacle lens for myopia is still one of the technical problems in the field of spectacles.
