This lens (1) is provided with the temporo side functional areas (4) of correcting the central optical zone (2) of retinal centre out of focus, the nasal side functional areas (3) of correcting temporo side retinal peripheral defocusing and rectification nasal retina periphery out of focus, between central optical zone (2) and nasal side functional areas (3), temporo side functional areas (4), transition region (5) is set.Lens (1) central optical zone (2) is prepared as single vision lenses (6) (as Fig. 1), Bifocal lenses (7), progressive lenses (8).Bifocal lenses (7) is prepared as looks far field (9), near reading range (10) (as Fig. 2).Progressive lenses (8) is prepared as looks far field (9), Zhong Ju district (11), near reading range (10) (as Fig. 4).
This lens (1) can be prepared as two kinds of nearsighted eyeglass and Farsighted lens.
The nearsighted eyeglass (1) of correcting retinal centre Myopia out of focus is prepared as single vision lenses (6), Bifocal lenses (7), progressive lenses (8).Single vision lenses (6) is prepared as concace mirror lens (12), plano lens (13), concace mirror lens (12) is in order to correct retinal centre Myopia out of focus, central Myopia out of focus is displaced on central fovea of retina backward, thereby obtains clear central vision.Plano lens (13) is to design in order there to be myopia tendency, and especially father and mother one side has bathomorphic normal visual acuity children, occurs for pre-Anti-myopic eye.Bifocal lenses (7) be prepared as concace mirror lens (12), plano lens (13) depending on far field (9), near reading range (10) is prepared as with respect to looking far field (9) refractive diopter increase+0.50D～+ 3.00D, preferably select refractive diopter increase+1.50D～+ 2.00D, be prepared as concace mirror lens (12), plano lens (13), convex lens sheet (14).Or the near reading range of Bifocal lenses (7) (10) are prepared as and merge the prismatic glasses (15) of additional substrate towards nasal side, the eyeglass number of degrees are 1 Δ～20 Δ (as Fig. 3), preferably select the eyeglass number of degrees 5 Δ～10 Δs, prismatic glasses can easing eyes visual fatigue.Progressive lenses (8), from looking Jing Zhongju district, far field (9) (11) near reading range (10), is prepared the refractive diopter+0.50D～+ 3.00D that progressively increases gradually, preferably selects the refractive diopter+1.00D that progressively increases gradually～+ 2.00D.Lens (1) central optical zone (2) preparation is become to progressive lenses (8), can alleviate and look nearly adjusting load, especially regulated the strong myopia children with esophoria.Prepare with respect to central optical zone (2) diopter increase+0.50D～+ 3.00D nasal side functional areas (3) and temporo side functional areas (4), preferably select diopter increase+1.00D～+ 1.50D, be prepared as concace mirror lens (12), plano lens (13), convex lens sheet (14).In order to be more preferably the refractive diopter of nasal side functional areas (3) and temporo side functional areas (4), can select retinal periphery dioptrometry, conventionally adopt fenestration infrared ray automatic optometry unit to measure, prepare the refractive diopter of nasal side functional areas (3) and temporo side functional areas (4) according to measurement result, avoid excessively correcting or owing strong, also can avoid because the symmetry number of degrees are corrected the antimetropia causing.
The Farsighted lens (1) of correcting retinal centre long sight out of focus is prepared as single vision lenses.Lens (1) central optical zone (2) is prepared as convex lens sheet (14), nasal side functional areas (3) and temporo side functional areas (4) are prepared as with respect to central optical zone (2) refractive diopter minimizing-0.50D～-3.00D, preferably select refractive diopter minimizing-1.00D～-1.50D, be prepared as concace mirror lens (12), plano lens (13), convex lens sheet (14).Central optical zone (2) convex lens sheet (14) of Farsighted lens (1) is corrected retinal centre long sight out of focus, corresponding temporo side retinal periphery and nasal retina peripheral myopic out of focus are corrected in nasal side functional areas (3) and temporo side functional areas (4), promote eyeball emmetropization process.
Preparation region on 270 ° of-90 ° of axis of the vertical radial line (VM) along optical centre, lens (1) central optical zone (2), be prepared into upper portion for subtended angle upwards, be positioned at 195 °～345 ° of minute surface periphery position clockwise direction axle positions, region, 60 °～150 °, circumference position angle, center section preparation is to arc or outwardly to outer arcuate, lower portion is downward subtended angle, be positioned at 30 °～150 ° of minute surface periphery position clockwise direction axle positions, region, 20 °～120 °, circumference position angle, center section is 10mm～40mm along horizontal radial line (HM) length of optical centre.Upper portion and the lower portion of lens (1) central optical zone (2) are prepared into upper and lower angle of release, the broad visual field of vertical radial line, avoid the technological deficiency that has tunnel vision of existing periphery out of focus lens, increase the visual field area of central optical zone (2) simultaneously, thereby had enough visual fields area to design Bifocal lenses (7) and progressive lenses (8).
Nasal side and the temporo side mirror sheet periphery position in lens (1) nasal side functional areas (3), temporo side functional areas (4) symmetry preparation region on 180 °～360 ° axle positions of the horizontal radial line (HM) along optical centre, nasal side functional areas (3) preparation is being positioned at 300 °～60 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle, and temporo side functional areas (4) preparation is being positioned at 120 °～240 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle.
Retinal periphery dioptric presents asymmetry phenomenon, and bathomorphic upside peripheral retina and downside peripheral retina dioptric present Myopia out of focus, and nasal side peripheral retina and temporo side periphery retina present long sight out of focus.Presbyopic upside peripheral retina and downside peripheral retina dioptric present long sight out of focus, and nasal side peripheral retina and temporo side periphery retina present Myopia out of focus.What dominate eyeball emmetropization process is horizontal radial line peripheral retina out of focus, and nasal side and temporo side periphery retina out of focus also present asymmetry, the more aobvious long sight out of focus of temporo side periphery retina or Myopia out of focus.In the time that refractive diopter is corrected in design lens (1) functional areas, more to follow and reduce this asymmetry as far as possible, be about to correct temporo side periphery retina refractive diopter and relatively strengthen.So, lens (1) must be designed to right and left eyes, its objective is temporo side functional areas (4) and nasal side functional areas (3) difference, that is to say: right eye eyeglass (1) nasal side functional areas (3) preparation is being positioned at 300 °～60 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle, temporo side functional areas (4) preparation is being positioned at 120 °～240 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle.Left eyeglass lens (1) nasal side functional areas (3) preparation is being positioned at 120 °～240 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle, and temporo side functional areas (4) preparation is being positioned at 300 °～60 ° of minute surface periphery position clockwise direction axle positions, region, 80 °～120 °, circumference position angle.
Lens (1) nasal side functional areas (3) and temporo side functional areas (4), at least apart from optical centre 15mm～20mm, at least occupy ° region, circumference position angle >=90, its objective is the rectification curative effect of guaranteeing functional areas.
