Description
technical field:
The utility model relates to the special chin bracket of the healthy table of a kind of Multifunctional myopia prevention.
background technology:
Eyeball is regulating under static state, and from the equality light beyond 5 meters after the dioptric had a look at, focus falls on the retina just, can be formed clearly as, the eye with this refractive status is called emmetropia.Before its focus drops on retina, can not be formed on the retina exactly clearly as, be called axial myopia; To the disperse light from target nearby, but there is height adaptive capacity, as long as target is to moving to certain distance at the moment, just can obtain eyesight clearly; Clinical manifestation is that distant vision declines, and near vision is normal; Visual fatigue; Outer hidden oblique or concomitant exotropia can occur, and it is at a glance high that slanting eye mostly is myopia degree; Often there is synchysis, muddiness in high myopia person, complicated cataract and conscious muscae genetic vision waves or visual impairment; Low, moderate person eyeground is generally unchanged or in leopard line shape eyeground, the lonely shape spot of myopia, high myopia person's optic papilla temporo side or peripheral cyclic choroidal atrophy, macular degeneration, hemorrhage, Fuchs (Fuchs) spot, posterior scleral staphyloma, and easily there is retinal hole and detachment of retina; High myopia person is slightly outstanding because of axis oculi director, accompanies that anterior chamber is comparatively dark and pupil is comparatively large simultaneously, and reverse slightly blunt to light; Eyesight can be promoted with concave spherical surface lens.
China is bathomorphic hotspot, and the illness rate of juvenile shortsightedness raises year by year, and orientedly to become younger, the trend of high number of degrees development.And pressure of entering a higher school, the environmental factor relevant to life modernization are as universal in computer, also will produce long lasting effect to myopia prevalence; Students in middle and primary schools' visual impairment is the current major issue affecting juvenile healthy, is related to the raising of whole national health quality; Myopia is not only medical problem, and has become the social concern that broad masses are concerned about jointly; How efficiently and effectively prevents and treats myopia, eyesight of protecting young people, and is the current major issue being badly in need of solving, and is also the major issue needing to everybody knows, everybody participates in; But current many people of also having understand less to bathomorphic preventive treatment knowledge, to such an extent as in prevention, attention is inadequate, in treatment, method is improper, has impelled near-sighted generation and development; Each building block of the healthy table of Multifunctional myopia prevention is extremely important.
summary of the invention:
The purpose of this utility model be in order to realize controlling student reading a book, do one's assignment time adopt the function of normal posture, provide the healthy table of a kind of Multifunctional myopia prevention special chin bracket.
The utility model adopts the technical combinations scheme of following mechanism part to realize its goal of the invention: the special chin bracket of the healthy table of a kind of Multifunctional myopia prevention, it is made up of convex lens assembly 1, bracket 2, expansion link 3, swivel mount 4, expansion link 3 is provided with telescopic adjustment block 6, swivel mount 4 is provided with locking nut 5; Convex lens assembly 1 is positioned at the upper forepart of chin bracket 3; Bracket 2 is positioned at the top of chin bracket 3; Expansion link 3 connects swivel mount 4 and bracket 2; Telescopic adjustment block 6 is positioned at expansion link 3 top; Locking nut 5 is positioned on front side of swivel mount 4.
The utility model according to the convenient function regulating chin bracket of the height of different people, is provided with expansion link 3 and swivel mount 4 in order to realize; Expansion link 3 connects swivel mount 4 and bracket 2.
Owing to have employed above technical scheme, the utility model achieves its goal of the invention preferably, the special chin bracket of the healthy table of this Multifunctional myopia prevention forces to control reading by chin bracket, distance when doing one's assignment, and height and gradient can be regulated according to different people, ensure comfort level, what be equipped with is the presbyopic glasses of 100 ~ 200 degree simultaneously, pre-myopia prevention; So just significantly can change student in study and with defect during computer, protect eyes, teenager is grown up better.
