Myopia is a common refractive disorder problem of the human eye and typically develops when the size/length of the eye grows beyond the focal length of the optical portion of the eye, in which case the optical image is formed in front of the retina with a positive defocus, known as myopic defocus. The human eye has a feedback mechanism that regulates eye growth to achieve an optimal balance between eye size/length and focal length of the optical portion of the eye, which is called emmetropization. When myopic defocus decreases, emmetropization mechanisms operate to retard eye growth in size until the retina coincides with the optical image position.

The invention provides a lens for preventing sports vertigo, and referring to fig. 1 and fig. 2, the lens for preventing sports vertigo comprises: a substrate; a correction ring set comprising a plurality of annular correction zones 20 coaxially arranged, wherein the annular correction zones 20 are positioned on the surface of the substrate and are arranged at intervals; a central correction zone 10 centrally disposed in the set of correction rings; and a spacer ring set including a plurality of annular spacer regions 30 coaxially arranged, between two adjacent annular correction regions 20, and between the innermost annular correction region 20 and the central correction region 10, forming the annular spacer regions 30.
In the present embodiment, the lens for preventing motion sickness can be used as an optical lens, a contact lens, a keratoplasty lens, a contact lens, etc. The base material can be resin, glass, hydrogel, silicon hydrogel, RGP, PC material, can set up three coaxial annular correction district 20 on the optical surface of base material, including the first correction ring 21, the second correction ring 22 and the third correction ring 23 of arranging in proper order from inside to outside. The three are spaced apart, the central zone 10 being centrally disposed within the first ring 21, the first zone preferably being circular and coaxial with the first ring 21, the outer edge of the central zone being spaced slightly from the inner edge of the first zone. The annular spacers 30 are formed between two adjacent annular correction zones 20, and between the first correction zone and the central correction zone 10. The annular spacer 30 includes a first spacer 31, a second spacer 32, a third spacer 33 and a fourth spacer 34 arranged in sequence from inside to outside, thereby forming a concentric lens structure. When the user wears the structure, the concentric circle structure is attached to the pupil position of the eyeball.
Conventional monofocal lenses have only one power, and objects viewed through the lens can be clearly imaged on the retina, while objects viewed through the periphery of the lens are imaged behind the retina, forming a peripheral hyperopic defocus, although the middle can be clearly seen. Because human eyes have a self-control mechanism of 'seeing clearly objects', eyeballs are lengthened backwards in order to eliminate peripheral hyperopic defocusing so as to achieve peripheral imaging on retinas, and as a result, the myopic degree is deepened. Therefore, the traditional spectacles are only worn clearly, and the optical design of the traditional spectacles does not achieve the effect of well controlling the increase of the myopia degree. If the periphery of the lens can be imaged on the retina or in front of the retina to form focus or peripheral myopic defocus, the motive force for lengthening the eyeball is cut off, and a stimulus signal for promoting the elongation of the axis of the eye is eliminated, so that the aim of inhibiting the myopia from deepening is fulfilled. Thus, the ideal optical control, in effect, would resemble the following figure: the central area should be clear and the peripheral image should fall a little before the retina, allowing the retina to move as far inward as possible without extending backward.
It can be understood that, for a myopic user, the focus of the optical structure of the eye is positioned in front of the retina of the eye, and the phenomenon of myopic defocus occurs, so that the user cannot see the picture clearly. The utility model provides a prevent lens of vertigo of moving, it is when supplementary user sees clearly the image, induce user's eyes benign growth, concretely, prevent lens of vertigo of moving includes central correction district 10, central correction district 10 is located the middle of the lens of vertigo of moving, thereby pupil and central correction district 10 approximately relative setting when user looks far away, the diopter of central correction district 10 corresponds with user's myopia ametropia's power, mostly negative value, in order to project the image clearly on user's retina, make user can see clearly the image when looking far away, the periphery of central correction district 10 is overlapped alternately and is equipped with annular spacer 30 and annular correction district 20, annular correction district 20 can form the image in front of user's retina, so set up, because the image of defocusing at this moment is located in front of user's retina, can restrain user's eye axis extension, in order to avoid user's myopia deepening, until user's eyeball's focus is unanimous with user's retina position, realize correcting user's eyesight.
In the present embodiment, the smaller the width of the circular spacer region 30, the smoother the imaging, the less dizzy during exercise, the clearer the visual imaging, the too large the interval between the circular correction regions 20, the extreme difference in degrees easily allows the eyes to adapt to one degree instead of the smoothness, the less accommodative ability of the eyes to follow up during rapid exercise and the more dizzy, and the unclear the visual imaging. By defining the width of the circular spacer 30 to be between 0.2mm and 1.6mm, vertigo symptoms during exercise of the user can be further alleviated.
In one embodiment, referring to fig. 1 and 2, the diopter of each annular correction zone 20 increases from the center to the periphery. In this embodiment, if the user's myopia degree is 500 degrees, it is recorded as "-5D", and the diopter of the first correction ring 21 is smaller than that of the second correction ring 22; the diopter of the second correction ring 22 is smaller than that of the third correction ring 23. So that astigmatism is refractive-corrected by the first, second and third correction rings 21, 22, 23, thereby improving the sharpness of the image. For example, the central correction zone 10 is set at-150 degrees, and the first, second, and third correction collars 21, 22, and 23 are set at 100 degrees, 150 degrees, and 200 degrees. The difference in refractive power between adjacent annular correction zones 20 is between 150 and 350 degrees. So as to avoid the wearing discomfort of the user caused by the excessively high difference value.
In one embodiment, referring to fig. 1 and 2, the widths of the annular spacers 30 are uniform. In the present embodiment, the annular spacer region 30 may be set to have the same width, and preferably 0.3mm in the present embodiment, thereby further reducing the distance between two adjacent annular correction regions 20 and avoiding the dizzy feeling of the user caused by the extreme difference in degree.
In addition, the width of each of the annular spacers 30 decreases from the center to the outer periphery in order. Specifically, the width of the first spacer ring 31 is 1.0mm, the width of the second spacer ring 32 is 0.8mm, the width of the third spacer ring 33 is 0.6mm, and the width of the fourth spacer ring 34 is 0.4mm.
In one embodiment, referring to fig. 1 and 2, the diameter of the central correction zone should be smaller than the pupil diameter of the user, therefore, the central correction zone 10 can be set in the range of 2.5mm to 5mm, for example; the widths of the first correction ring 21, the second correction ring 22 and the third correction ring 23 can be set within the range of 0.2mm to 0.28mm, and the pupil diameter of an adult is about 6mm. Thereby ensuring that the diameter of the lens structure is less than the pupil diameter. I.e. the central correction zone 10, the first correction collar 21, the second correction collar 22 and the third correction collar 23 can all overlie the pupil.
In one embodiment, referring to fig. 1 and 2, the diopter of the central correction zone is normal diopter, and the diopter of the annular correction zone is 150 to 350 diopters. The annular interval area is in smooth transition with the annular correction area. The diameter of the square motion dizzy lens is 8-10mm. By setting the width of the annular interval area to be 0.3mm and enabling the annular interval area to be in smooth transition of the annular correction area, vertigo caused by extreme difference of degrees is avoided.
The invention also provides a soft hydrophilic contact lens, which applies the lens for preventing motion vertigo, referring to fig. 1 and fig. 2. In the present embodiment, the substrate is made of resin or glass, and three coaxial annular correction zones 20 including a first correction ring 21, a second correction ring 22 and a third correction ring 23 are arranged on the optical surface of the substrate from inside to outside. The three are spaced apart, the central correction zone 10 being centrally disposed within the first correction ring 21, the first correction zone preferably being circular and coaxial with the first correction ring 21, the outer edge of the central correction zone being spaced slightly from the inner edge of the first correction zone. The annular spacers 30 are formed between two adjacent annular correction zones 20, and between the first correction zone and the central correction zone 10. The annular spacer 30 includes a first spacer 31, a second spacer 32, a third spacer 33 and a fourth spacer 34 arranged in sequence from inside to outside, thereby forming a concentric lens structure. When the user wears the structure, the concentric circle structure is attached to the pupil position of the eyeball. According to the technical scheme, the anti-motion vertigo lens comprising the central correction area and the annular correction area 20 is arranged, a user can obtain a clear object image through the central correction area 10, and meanwhile, light rays focus the object image on the front side of the retina through the annular correction area 20 to guide glasses to adjust so as to achieve the purpose of treating myopia. Meanwhile, the width of each of the ring spacers 30 is maintained at 0.2 to 1.6mm by adjusting the width of the ring spacers 30. The smaller the width of the circular spacer 30, the smoother the imaging, the less dizzy it is when moving, the clear vision imaging, the too large the spacing between the circular correction zones 20, the extreme difference in degrees easily allows the eye to adapt to one degree rather than smooth, the less accommodative ability of the eye is followed when moving rapidly and the dizzy it is easy, and the unclear vision imaging. By defining the width of the annular spacer 30, the vertigo symptom of the user during exercise can be further alleviated.
The invention also provides a pair of glasses, please refer to fig. 1 and fig. 2, the pair of glasses adopts the above-mentioned anti-dizziness glasses structure, and the lenses are arranged on the glasses frame. The anti-dizziness glasses structure can be used on contact lenses and frame type glasses. In this embodiment, the lens is formed by cutting the base material, and an anti-glare glasses structure is disposed on the lens. In the anti-dizziness glasses structure, the annular correction area and the annular spacer area are in smooth transition, the fillet transition can be set, the curve transition can also be adopted, and the diopter range difference is avoided.
The user can obtain clear object images through the central correction area 10 on the lens, and meanwhile, the light rays focus the object images on the front side of the retina through the annular correction area 20 so as to guide the glasses to adjust, and the purpose of treating myopia is achieved. Meanwhile, the width of each of the ring spacers 30 is maintained at 0.2 to 1.6mm by adjusting the width of the ring spacers 30. The smaller the width of the circular spacer 30, the smoother the imaging, the less dizzy it is when moving, the clear vision imaging, the too large the spacing between the circular correction zones 20, the extreme difference in degrees easily allows the eye to adapt to one degree rather than smooth, the less accommodative ability of the eye is followed when moving rapidly and the dizzy it is easy, and the unclear vision imaging. By defining the width of the circular spacer 30 to be between 0.2-1.6mm, the vertigo symptom during the exercise of the user can be further alleviated.
