The invention will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present invention have been illustrated in the accompanying drawings, it is to be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The utility model provides a prevention is near-sighted and reduces study mirror of near-sighted number of degrees, including lens, mirror leg and picture frame, the lens includes:
a far vision zone lens, 2/5-1/2 of the upper part of the lens;
near zone lens, fix and fix to far zone lens below, account for 3/5-1/2 of inferior part of the lens;
wherein, near zone lens includes:
the base of the triangular prism is arranged inwards;
the composite lens is arranged at the center of the interior of the triple prism in an implanted manner and is integrally formed with the triple prism;
wherein, the degree of the far vision zone lens is matched with the naked eye vision of a user.
The degree of the far vision zone lens is matched with the naked eye vision of a user, so that the far vision zone lens is clear, accurate and free of negative difference, when the human eyes see far, the two eyes are in a relaxed state, and far (more than 5 meters) parallel light rays penetrate through eyeballs and are focused on the retina of the eye ground, so that the target objects can be seen clearly through brain imaging.
Preferably, the thickness of the far vision zone lens is 2.5-3mm, and the thickness of the near vision zone lens is 4-5 mm.
Wherein, the thickness of the composite lens is 2-3 mm.
Further, the composite mirror is a convex lens.
The composite lens is implanted inside, so that the composite lens and the near vision zone lens are integrally formed, the distance between the lens and an eyeball is 4-5mm, effective data is more real, and the composite lens has the advantages of light weight and better wearing comfort compared with a double-layer composite lens, in addition, the double-layer composite lens is in a work tension state when the eyes see the near, and the ciliary muscle of the eyes works to enable the crystalline lens to become convex (adjust); the extraocular muscles work to align the intra-ocular convergence to the target (set); the pupil sphincter works to contract the pupil, and the above state becomes a near-seeing three-linkage visually. The eyes are easy to be in a fatigue state for a long time when people look at the near part for a long time, the axis of the eyes is lengthened, and the myopia is deepened. The utility model discloses a study mirror can effectively reduce the strength of eyes ciliary muscle and extraocular muscle when both eyes are seen near, for adjusting not enough design when seeing near (lower light zone) and compensated convex lens and additional basement prism inwards, has got rid of and has only added convex lens and relax the drawback of regulation, makes both eyes really reach the state of relaxing the rest.
When the glasses are prepared, the appropriate bottom-inward triangular prism is added, which can help to improve the convergence effect and has a certain effect on eliminating asthenopia.
The regulation and convergence are of great significance in ensuring the eyesight of the human eyes and maintaining the binocular single vision, and are very important for understanding some related physiological and pathological phenomena (such as abnormal eye position, asthenopia and the like) and the relationship with the occurrence and development of the myopia.
