Description
Affiliated technical field
The invention belongs to glasses and myopia preventing and treating technical field, be specifically related to prevent and treat near-sighted glasses and mirror holder.
background technology
Along with social development and scientific-technical progress, the range of application of computer is more and more, and for study and work, people will face computer, books, file, data for a long time, and the most important sense organ of human body---eyes are bearing huge burden.Finish one's primary school, junior middle school, senior middle school, the ratio of myopia is more than half, postgraduate university student myopia ratio is up to more than 70%, myopia has affected employment, also to life, makes troubles, the control of myopia should cause social concern.The reason of myopia is by social recognition, and except congenital myopia, the main cause of myopia is exactly to see that for a long time object nearby causes.Due to long-time close eye, the crystalline lens of eyes, often in in-plant high-pressure adjustment state, recovers less than original normal condition after eye fatigue, has become pseudo-myopia, as recovered not in time, if things go on like this, has just become true myopia.
The myopia prevention product occurring in the market has a variety of, the sitting posture tilt alarm that has the fault of preventing, there is the Lower jaw support of the nose drop of preventing to hold up device, the glasses that also have convex lens to be combined with prism, the combined lens that also has prism, concavees lens to be combined with convex lens gradual change.Also have in myopia and no longer developed the laser cornea operations by operative treatment, these products are each has something to recommend him, and relative merits coexist.What prevent at present the more use of hypometropia is bifocals and gradual multifocal spectacles, and light district, eyeglass top sees far, and light district, bottom is seen closely.But eyeglasses frame is all fixed form, for seeing that written word can be suitable for, but see that computer can only be used glazing district to be just unsuitable for seeing closely.With hanging frame type glasses, frequently get that to wear attached extension mirror very inconvenient again.
summary of the invention
Invention is intended to overcome the weak point existing in above-mentioned technology, a set of simple and easy to do related preventive and treatment solution are provided, and provide a kind of simple in structure, wear conveniently, effect objectively prevents and treats spectacles, can see written word, Neng Yongxiaguang has seen computer in district again.Medical circle has been found that the near-sighted origin cause of formation is except congenital heredity, and long-time close eye is to cause near-sighted root.So prevent that near-sighted generation from must reduce close eye, increase and look in the distance with eye.The present invention is understanding in depth on the basis of causes of myopia, eliminate near-sighted factor, be equipped with easy to use, can adjust flexibly the spectacle frame in light district up and down, the convex lens sheet in energy Xia Guang easy to use district while making to see near objects, make near objects be imaged on the place of farther place, seeing that computer Shi Ye Neng Yongxiaguang district sees closely, make people really away from myopia.
Technical scheme
The technical scheme that its technical matters of invention solution adopts is:
Prevent and treat near-sighted rising glasses, mainly comprise the mirror holder being comprised of mirror leg 1, picture frame 2 and nose support 3, the interior eyeglass 12 that arranges of picture frame 2, is characterized in that: between nose support 3 and picture frame 2, jacking gear is set.
Described jacking gear is the stretching structure of a plurality of sleeve pipes, and the interior spring 15 that arranges of telescopic tube 10, arranges locking device or rising button 8 on mirror leg 1 or mirror holder.
Described telescopic tube 10 tops are fixedly connected with the crossbeam 7 of mirror holder, and expansion link 11 is fixedly connected with nose support beam 4, and expansion link 11 is slidably connected with telescopic tube 10, and the two ends up and down of telescopic tube 10 or expansion link 11 arrange lower snap close 18 and upper snap close 19.
Described jacking gear is Electronic Control apparatus for automatically lifting.
Described Electronic Control apparatus for automatically lifting comprises micromachine 20, battery 23, lifting action topworks and automatic control switch.
Described lifting action topworks is screw-drive mechanism.
Described automatic control switch comprises transmitter, sensor 23 and control circuit.
Also comprise solar cell 24.
Described transmitter is with clamping device.
Described eyeglass 12 is convex lens, concavees lens, Bifocal lenses or multifocal lens.
Beneficial effect
The control myopia rising glasses of invention have following beneficial effect:
1, safety.Do not operate on and do not do laser surgey and just can allow eyesight reply gradually and prevent that myopia from further increasing, and can avoid doing injury and the late complication that laser surgey causes eyes cornea.
2, simple in structure, wear conveniently.Only need once pressing one look in the distance and see nearly mutual switching by completing.
3, effect is objective.Whenever and wherever possible in the state of looking in the distance, stopped to see for a long time that near myopia produces root, can prevent the phenomenon that long-time viewing screen visual impairment behind the scenes and eyes grow dim before computer, after taking off one's glasses, look on the contrary thing extremely clear.
4, be applicable to seeing for a long time computer.If see computer with common progressive multi-focus lens, because computer is in eyeglass glazing district, glazing district is not suitable for seeing computer nearby.The present invention can overcome the defect that progressive multi-focus lens is not suitable for seeing computer, when seeing computer, only need press rising button, and rising glasses of the present invention will raise, and eyes are in lower smooth zone position, just can Yong Xiaguang district computer nearby.
The present invention is applicable to enterprises and institutions, research institutions, faculty and staff, student and computer user, has obvious prevention and treats near-sighted effect.If promote to come, will allow teenager of future generation no longer endure the puzzlement in modern times to the fullest extent.
