Detailed Description
The utility model is further described below with reference to the accompanying drawings.
According to the figures 1-4: the utility model provides a novel myopia defocusing lens structure: the lens comprises a lens structure, wherein the lens structure is tightly and seamlessly arranged by 540 hexagonal microstructures, and the hexagonal microstructures comprise a microlens area 5 and a substrate area 6; the microlens region 5 provides defocus stimulus and the base region 6 provides vision correction function; the lens structure is sequentially provided with a vision correction area 1, a transition area 2, a central defocus prevention and control area 3 and a peripheral defocus prevention and control area 4 from inside to outside; the central area of the lens structure is formed with a hexagonal microstructure to form an exquisite edge 7.
The diameter of the central area is reduced by arranging the closely arranged hexagonal microstructures to form an exquisite edge 7 in the central area, so that the myopia prevention and control effect is enhanced; and the hexagonal microstructure can provide higher defocusing filling rate, increase defocusing stimulation, and can solve the problems that the defocusing stimulation of the existing myopia defocusing lens is weaker and the myopia prevention and control effect is poor.
The vision correction area 1 is used to place prescription powers. The transition zone 2 is the range of two circles of outward diffusion of the vision correction zone 1, and the defocus amount of the transition zone 2 is +300 degrees. The defocus amount of the central defocus control region 3 is +350 degrees, and the defocus amount of the peripheral defocus control region 4 is +400 degrees.
The transition zone 2 is added, so that the comfort level of primary wearing can be improved, and the transition between the vision correction zone 1 and the prevention and control zone is more natural.
The minimum diameter that exquisite limit 7 can form can reach 8.0mm, makes defocusing stimulus more reach the sensitive scope of macula lutea fovea to reach the effect of strengthening myopia prevention and control.
In the minimum defocus period unit of the lens structure, the defocus portion can be pieced into two complete hexagons, and the blank area can form 2: 1.
The characteristics of the hexagons can make the defocused parts spell into two complete hexagons in the minimum defocused periodic unit of the lens structure, and the blank area can form 2:1, enables an out-of-focus fill rate of about 67% to be achieved, the out-of-focus stimulus being greater than a conventional 50% out-of-focus fill rate.
Principles of the utility model
Because the lens structure is closely and seamlessly arranged by 540 hexagon microstructures, the hexagon microstructures can form a concave-convex exquisite edge 7 in the central area of the lens structure, as shown in fig. 3, compared with the traditional circular arrangement, the diameter of the central area can be smaller at two symmetrical convex parts of the exquisite edge 7, and can reach 8.0mm, so that defocusing stimulation can reach the sensitive range of the macula lutea fovea more, and the myopia prevention and control strengthening effect is achieved. Meanwhile, compared with a round boundary, the concave-convex exquisite edge 7 brought by hexagonal arrangement can bring defocusing stimulation in different directions. The hexagons have spatial symmetry, and when the field of view moves on the lenses, the number of lenses is always stable; when the visual field of other similar products moves, the fluctuation of the imaging effect can be brought by the change of the number of lenses, so that the application can reduce the visual swimming sensation and bring stable visual experience all the time.
As shown in fig. 4, in the minimum defocus period unit of the lens structure, the defocus portion can be pieced into two complete hexagons, and the blank region can form 2:1, the defocusing filling rate can reach 2/3 approximately 67%, and the defocusing stimulus is larger compared with the conventional 50% defocusing filling rate, so that the problems of weaker defocusing stimulus and poor myopia prevention and control effects of the existing myopia defocusing lens can be solved.
The utility model and its embodiments have been described above with no limitation, and the actual construction is not limited to the embodiments of the utility model as shown in the drawings. In summary, if one of ordinary skill in the art is informed by this disclosure, a structural manner and an embodiment similar to the technical solution should not be creatively devised without departing from the gist of the present utility model.
