Accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram of the present utility model;
In figure: 1-central spherical optical region, the other central spherical optical region of 2-, 3-peripheral optical zone.
Embodiment
As shown in Figure 1, a kind of 360 degree of complete burnt near-sighted prevention and control eyeglasses, it comprises full focus lens element, it is characterized in that: described full focus lens element includes central spherical optical region 1, other central spherical optical region 2 and peripheral optical zone 3, described central spherical optical region 1 periphery is other central spherical optical region 2, and the periphery of described other central spherical optical region 2 is peripheral optical zone 3 to the edge of eyeglass.
As shown in Figure 1, described central spherical optical region 1 is traditional concavees lens design, and its shape is the half-oval shaped that two major axis are equal, and its major axis radius is 7.5mm, for correcting the central vision defect of wearer, for it provides clearly central vision.
As shown in Figure 1, described other central spherical optical region 2 is progressive optical region, and its ring width major diameter is 15mm, and described other central spherical optical region 2 is 22.5mm with the major axis radius of central spherical optical region 1 central point.
As shown in Figure 1, described other central spherical optical region 2 and peripheral optical zone 3 are peripheral progressive optical region, adopt asymmetric design mode, because eyeball in the process of reading is downwardly towards tilted, therefore peripheral progressive optical region adopts asymmetric design mode, meets the eyesight balance of right and left eyes.
As shown in Figure 1, described peripheral optical zone ring width major diameter is 15mm, is 37.5mm with the major axis radius of central spherical optical region central point.For the adjustment eye of eyes maximum angle up and down, by degree of the subtracting gradual change of the number of degrees, greatly alleviate the eyes muscular fatigue of vision accommodation.
As shown in Figure 1, described other central spherical optical region minute surface successively decrease 25 degree, peripheral optical zone minute surface successively decreases 25 degree.
As shown in Figure 1, described central spherical optical region, other central spherical optical region and peripheral optical zone all keep minute surface to have lower surface astigmatism, eyeglass is kept to have lower surface astigmatism for central spherical optical region 1, ensure the optical clarity of wearer, simultaneously, in order to make wearer have larger visual angle, along the other central spherical optical region 2 in horizontal meridian direction and peripheral optical zone 3, there is lower surface astigmatism at eyeglass equally.
As shown in Figure 1, the utility model comprises this full focus lens element and includes central spherical optical region 1, and its radial design is 7.5mm; Other central spherical optical region 2, its radial design is 22.5mm; Its radius of peripheral optical zone 3 is 37.5mm; Described other central spherical optical region 2 and peripheral optical zone 3 are all progressive optical region, the edge eyeglass of positive multiplying power.Described central spherical optical region 1 is tested by actual eyeglass lens power and is joined; Other central spherical optical region 2 subtracts 25 degree by actual optometry and tests and join; , according to the other central spherical optical region number of degrees, again successively decrease 25 degree to test and join in peripheral optical zone 3.
As shown in Figure 1,360 degree of complete burnt near-sighted prevention and control lens elements of the present utility model are include central spherical optical region 1, other central spherical light region 2 and are progressive optical region, the edge eyeglass of positive multiplying power relative to other central spherical light region 1 and peripheral optical zone 3.Central spherical optical region 1 is traditional concavees lens design, its shape is the half-oval shaped that two major axis are equal, center image images in amphiblestroid center, and its peripheral images images on retina or before retina equally, like this while ensure that central sharp eyesight, peripheral visual acuity can not stimulate the lengthening of eyeball, namely the signal that a myopia stops deepening is sent, so this eyeglass is simply generous for the intensification of retarding myopia the utility model structure that has a significant effect, easy to use, satisfactory for result, spectacles prevention and control to innovate greatly functionally.Not confocal difference refraction on full focus lens, define the imaging curved surface that is similar to eyeball curvature, ensure comfortableness and the sharpness of whole retina image-forming, eliminate peripheral retina long sight difference out of focus, solve the factor of the myopia development stimulation that conventional myopic glasses cause, make the growth of axis oculi be tending towards slow or stop, thus reaching the effect of control or retarding myopia intensification
As shown in Figure 1, the utility model technology is used in the eyeglass lens power of 1200 degree of myopia of 75 degree, and its surface structure is simple, easy to use, and the myopia degree controlling eyes increases, and successful is an innovative technology in spectacles field.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; institute is understood that and the foregoing is only specific embodiments of the invention; the protection domain be not intended to limit the present invention; all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
