Below in conjunction with accompanying drawing, lens of the present invention is described in further detail:
A kind of nasal side temporo lateral areas periphery out of focus spectacle lenses, for rigid spectacle lenses or for pasting the soft lens that overlays on it, hereinafter referred to as this lens.On this lens (1) eyeglass visual field, be provided with three central optical zone (2), nasal side functional areas (3) and temporo side functional areas (4) that refractive diopter is different.Prepare three regions: one is the central optical zone (2) of correction of myopia retinal centre Myopia out of focus, another Two Areas: be respectively the nasal side functional areas (3) of correcting temporo side retinal periphery relative hypermetropia out of focus, the temporo side functional areas (4) of correcting nasal retina periphery relative hypermetropia out of focus.Different refractive diopters are prepared in three regions, in other words, prepare different refractivity, main innovation of the present invention is that nasal side functional areas (3) and temporo side functional areas (4) are arranged to in functional areas, and prepared different refractive diopters, thereby reach functional areas double effects: can correct retinal periphery relative hypermetropia out of focus, can eliminate or reduce again retinal periphery dioptric asymmetrical state.
This lens (1) is optionally prepared as closed, downward fenestration or wherein any type of lenses of fenestration up and down.When lens (1) design, first eyeglass visual field is marked off to horizontal radial line (HM), vertical radial line (VH), axle position (as Fig. 1), the difference of the axle position between two axle positions is called position angle.
Central optical zone (2) is closed, in centre region, eyeglass visual field, be arranged to positive circle (5) (as Fig. 4), horizontal oval (6), perpendicular oval (7) (as Fig. 7), nasal side functional areas (3) and temporo side functional areas (4) are arranged on eyeglass visual field nasal side and 180° region, temporo side periphery position angle, and by central optical zone (2) all in it.The disclosed periphery out of focus spectacle lenses of China Patent No. 2006800441239,2008801159183 also belongs to closed eyeglass, the patent No. 2006800441239 is that positive circle, the patent No. 2008801159183 are for horizontal oval, its technology significant difference is: the functional areas of front two patents are regardless of nasal side and temporo side, and technical solution of the present invention is to be nasal side functional areas (3) and temporo side functional areas (4) by function distinguishing.
Central optical zone (2) is downward fenestration, extend in eyeglass visual field centre and to underside area (14), be arranged to nail-shaped (8) (as Fig. 8), feather spherical (9) (as Fig. 9), underside area (14) is arranged on region, 20 °～120 °, side periphery position angle under eyeglass visual field, and nasal side functional areas (3) and temporo side functional areas (4) are arranged on eyeglass visual field nasal side and region, 120 °～170 °, temporo side periphery position angle.Design downward fenestration, object is the relatively narrow technological deficiency of downward visual field of fixation that overcomes existing periphery out of focus spectacle lenses, especially wears class hour on children myopia, has expanded field range.
Central optical zone (2) is fenestration up and down, be arranged on eyeglass visual field centre and extend to upper-side area (15), underside area (14), being arranged to interior arc line shaped (10) (as Figure 10), out circle (11) (as Figure 11), horizontal linear shape (12) (as Figure 12), straight vertical linear (13) (as Figure 13).The upper-side area (15) of central optical zone (2) and underside area (14) respectively occupy eyeglass visual field upside, region, 20 °～120 °, lower side periphery position angle, and nasal side functional areas (3) and temporo side functional areas (4) are arranged on eyeglass visual field nasal side, region, 60 °～160 °, temporo side periphery position angle.Central optical zone (2) are designed to fenestration up and down, not only ensured central optical zone (2) extremely wide open scope, but also can regional area selectivity correct retinal periphery relative hypermetropia out of focus, more meaningfully, can there is object to correct nasal side and temporo side retinal periphery relativity dioptric asymmetrical state.
Central optical zone (2) is prepared as plano lens, concace mirror lens, is 8mm～30mm along the horizontal radial line of optical centre (HM) length.
