Abstract

The invention relates to a multifunctional myopic control eyeglass. The eyeglass which comprises a glass frame with height-adjustable nose supports, and eyeglasses is characterized in that: each eyeglass comprises an upper far luminosity zone, a middle zone and a lower close reading zone; and there is a visual channel with two degree changes, wherein one degree change is between the optical center of the upper far luminosity zone and the optical center of the middle zone just below the upper far luminosity zone, and the other degree change is between the optical center of the middle zone and the optical center of the close reading zone just below the middle zone. The eyeglasses are specially divided into three zones for the zero adjustment and the zero aggregation of reading and writing in the invention, so problems of the adjustment and the aggregation of close range reading and writing are thoroughly solved, the visual fatigue is eliminated, and myopia and degree increase are prevented, thereby present computer times of the comprehensive eye utilization are complied. The multifunctional myopic control eyeglass which allows previous neglected computer groups to be substantially facilitated allows the visual field to be clear, real and stable through the humanized zone height of each zone of the eyeglasses. The three zones which are used for cooperating with the adjustment of the eyeglass frame allow an image jumping phenomenon to be avoided. The wearing position of the eyeglass is accurate to guarantee the correct utilization of each zone, prevent the generation and the development of myopia caused by the fatigue of internal and external muscles of eyes and ciliary muscles.

Description

Multi-functional myopia control mirror

Technical field

The present invention relates to the glasses of a kind of related preventive and control, particularly relate to the multi-functional myopia control of a kind of student and computer work person mirror.

Background technology

The bathomorphic cause of disease: environmental factor, inherent cause and other.Wherein the myopia that causes of environmental factor is for the most common, it main because excessive near work cause.Long-time near work mainly causes inner and external flesh of eyes and ciliary muscle tired, show as adjusting and convergence excess and (or) inharmonious.

When facing or during the binocular fixation distant place of myopia after being corrected, intraocular flesh and the extraocular muscle of eyes are in relaxation state, binocular visual axis is parallel, and set is zero.The ciliary muscle of eyes also is in complete relaxation state, and this moment, eye's lens was adjusted to zero.Intraocular pressure does not receive external force and changes.The generation of myopia will be eased with development.So facing or be corrected eye is engaged in the wild worker's myopia of long sight for a long time and changes very little.

Intraocular flesh shrinks and strengthens when closely reading and writing, and extraocular muscle also will keep certain force of strain, just can make eyeball remain on stable reading position, and inner and external flesh of eyes shrinks the eyeball internal pressure is increased.In closely read-write, move after the change of ciliary muscle contraction crystalline lens is protruding simultaneously, also increased intraocular pressure.Because the inner and external flesh of eyes of long period and the contraction of ciliary muscle cause the eyes antero posterior axis to prolong, the near-sighted number of degrees increase.

The product or the patent that when closely reading and writing, have prevention and control myopia to announce: ZL03248065.2 ZL200820025315.1, ZL200720126208.3, ZL200820104382.2 etc.; All be about the theoretical research and the application on " on far with dioptric basis; add ", prevention and the control of alleviating near work eye fatigue and myopia is had certain effect with the inside prism of convex lens associating substrate.But mostly these glasses are convex lens and the qualitative application of prism; Lower and regulate and set; But do not give they with reading distance, and interpupillary distance between carry out good quantitative examination, make it on reading distance inner and external flesh of eyes and ciliary muscle and do not reach fully and loosen.Glasses are heavier simultaneously, can not far use again, so the prevention and control effect is not really perfect.

Summary of the invention

Beneficial effect of the present invention:

1, three districts have been told in view of eyeglass; Computer work district, middle part with all be on far with dioptric basis closely with read area; Add with the inside prism of convex lens associating substrate, be used to read and write acyclic homologically trioial joint and null set, thoroughly solve the adjusting and the set problem of closely read-write; Eliminate visual fatigue and prevent that the myopia and the number of degrees from increasing, complied with comprehensive computer age now with eye.Greatly facilitate unheeded in the past cybraian.

2, each trivial height ratio of eyeglass is than hommization, because the comfortable thing state of looking of eye has certain scope fluctuation.In each district, it is true stable to get a clear view like this.

3, be divided into the adjusting of three districts and cooperation mirror holder, avoided jumping as phenomenon.More priorly be that the wearing position of accurate glasses is guaranteed the correct use in each district.If be adjusted into the eye position of read-write and crystalline lens fully and look state far away, acyclic homologically trioial joint and null set when promptly reading and writing, inner and external flesh of eyes and ciliary muscle just can be tired, and myopia just can (or slowing down) takes place and develops.
