Description
Technical Field
The utility model relates to a myopia prevention and control glasses specifically is a myopia prevention and control glasses based on lens array.
Background
In the non-accommodative state of the eye, if an object is imaged behind the retina for a long time, the axis of the eye of a human being is elongated, so that so-called out-of-focus myopia is formed, which is a phenomenon that is common in adolescents.
The usual spectacles are now spherical lenses, i.e. the centre-to-edge power of the spectacles is the same. However, since the retina of the human eye is not a plane, it requires a gradually increasing power from the middle to the outside when actually correcting the diopter of the human eye. When correcting central diopter with spherical mirror, the edge can be corrected the overhead to lead to peripheral vision can form images behind the retina, wear for a long time and can form out of focus myopia, thereby deepen patient's near-sighted power.
In order to solve the above problems, for example, chinese patent publication No. CN110618542A discloses a spectacle lens capable of adjusting eye muscles, comprising a spectacle lens main body, wherein the spectacle lens main body is provided with a plurality of annular array zones, each annular array zone is circumferentially provided with a plurality of microlenses, the spectacle lens main body is further provided with a circular conventional imaging zone and an annular conventional imaging zone for correcting ametropia, the circular conventional imaging zone, the annular conventional imaging zone and the plurality of annular array zones are concentric, the radius of the circular conventional imaging zone is equal to the inner diameter of the annular array zone with the smallest ring diameter, and the inner diameter of the annular conventional imaging zone is equal to the outer diameter of the annular array zone with the largest ring diameter; the diopter of the micro lens is different from that of the spectacle lens, and the imaging positions of different annular array belts are different. The spectacle lens capable of adjusting eye muscles can adjust the eye muscles, relieve ciliary muscles and weaken the pressure applied to the eyeball and the intraocular pressure by using the eye extraocular muscles for a long time while correcting the vision, thereby reducing and correcting the myopia diopter of the eyes.
Also as disclosed in chinese patent publication No. CN110554515A, an ophthalmic lens comprising lenslets for preventing and/or slowing myopia progression may utilize a contact lens incorporating a non-coaxial lenslet array having an add power to create non-coaxial myopic defocus in the optical zone of the lens to prevent and/or slow myopia progression. The positive non-coaxial lenslets cover about twenty to eighty percent of the central pupil area to transmit light at a positive focus in front of the retina to slow the rate of myopia progression.
At present, the above patents have certain defects in the practical operation process, and in order to prevent the defocus myopia formed behind the retina due to the peripheral vision imaging, a lens array method is adopted, a series of small positive lenses with the light adding range of 1.00-4.50D are added at the periphery of the lens, so that the peripheral vision of the lens is imaged on the retina of a human eye or in front of the retina, the external cause of the defocus myopia is effectively eliminated, the purpose of myopia prevention and control is achieved, and the lens is imaged behind the retina in the peripheral vision so as to ensure that the vision area has no astigmatism interference.
