Background technology

Ortho-K originates from the U.S., and after the development of 50 years, oneself was applied in global more than 60 a countries；It is to adopt The Ortho-K piece designed with a kind of Special Inverse geometric shape, inner surface are made of multiple segmental arcs.Eyeglass and tear layer point Cloth is uneven, and resulting hydrodynamics effect changes cornea geometric shape, is being worn over cornea forepart during sleep, is progressively making cornea Curvature flattens, axis oculi shortens, and so as to effectively prevent the development of myopia, is known as that " sleep can just control and correction of myopia Technology ".Result of study shows that Ortho-K can quickly and effectively reduce 1.00-5.00D myopia degree, significantly improve middle minuent The uncorrected visual acuity of myopia, quality of making the life better control the development of adolescent myopia.But Ortho-K is also simply temporary Change cornea geometry situation to property, reduce or eliminate myopia degree, two pain spot problems can not but solve：Ortho-K stops wearing Original eyesight state that uncorrected visual acuity can be fallen after rise rapidly afterwards；Ortho-K wear with and nursing process it is extremely complex, exist Some potential safety problems.Under this background condition, for two pain spot problems of Ortho-K, one kind makes Ortho-K The auxiliary device (M5D light leads to mirror) of function upgrading comes into being, its appearance is another milestone of moulding of modern cornea The leap of formula.

The content of the invention

In order to overcome the shortcomings of existing orthokeratology, the utility model, which provides one kind, makes Ortho-K function upgrading Auxiliary device (M5D light leads to mirror).

A kind of auxiliary device for making Ortho-K function upgrading, two pieces of eyeglasses are one group, and lens barrel is during both ends are penetrating There are one group of fixing len in empty tube shape, one end, and the other end is equipped with one group of movement eyeglass of embedded groove, and the gear frame connection of transmission mechanism moves Movable plate, movable plate connect one group of movement eyeglass, when the gear frame of transmission mechanism moves so that the related one group of movement eyeglass of movable plate It is moved along lens barrel, lens barrel includes left lens barrel and right lens-barrel, and casing connects left lens barrel and right lens-barrel.

Actuating unit includes power housing, power transmission shaft, clockwork spring disk, wind up turn-button and gear frame, fixing len, movement Eyeglass is all connected to the outside of housing, and power transmission shaft is installed on the inside of power housing, and one end of power transmission shaft is provided with Driving gear, the other end are provided with partial gear, and the periphery wall of clockwork spring disk is provided with external toothing, and driving gear is nibbled with external toothing It closes, the mandrel of clockwork spring disk extends to the outside of power housing, and mandrel connects the turn-button that winds up；Gear frame is movably set in power housing Inside, gear frame are internally provided with rack chamber, the first rack and the second rack are both provided on two opposite inner walls of rack chamber, Partial gear is arranged inside rack chamber, and is coordinated with the first rack and the second rack.

A kind of auxiliary device for making Ortho-K function upgrading is also personalizedly attached in addition to the myoporthosis amount on basis The dynamic refraction load capacity for starting the optimization training of eyes entirety visual performance, this specific dynamic refraction load capacity are added It can generally change in -12.00D--+5.00D sections, so that its visual performance of wearer obtains during nature is with eye Sufficiently optimize and perfect.

Why Ortho-K can allow wearer while good natural uncorrected visual acuity is obtained, and can realize The target that the effect control myopia number of degrees increase, basic reason, which is that cornea is moulding, revolutionizes retinal peripheral defocusing state, Realizing the conversion of periphery defocus property -- peripheral hyperopia defocus is converted for peripheral myopic defocus.It is angle that M5D light, which leads to mirror, The important breakthrough of film shaping technology function upgrading, major technique Conception changing are exactly by the only consideration of original Ortho-K The moulding amount of correction become more scientific rational dioptric load capacity so that cornea complete it is moulding after to give eyes one specific again The dynamic refraction load of magnitude.

M5D light leads to the correction of refractive errors demand that mirror considers not only Myopia defocus, and also adding additional load dioptric needs It asks, so its dynamic refraction variable quantity can be more than significantly correct amount.

M5D light, which leads to the large-scale dioptric load capacity of mirror, will necessarily trigger crystalline lens to adjust compensation, and adjusting can not only after supplementing Retina focus state is enough maintained, and the regulatory function enhanced for needs is the process of a lasting intensive training.More Importantly, with the complete release of load dioptric, focus state can be towards defocus direction change, and at this moment, emphasis is for feel work( The optimization of energy starts -- by the ability of feel, retina fuzzy image is converted to steady and audible brain vision.

In the case where M5D light leads to mirror booster action, Ortho-K becomes peripheral myopic defocus by peripheral hyperopia defocus Characteristic is more notable, allows the myopia number of degrees are more effective, are more reliably controlled；

In the case where M5D light leads to mirror booster action, Ortho-K is general to be spaced 7 days even for more time without wearing daily It wears once, effective reduction is polished and complication；

In the case where M5D light leads to mirror booster action, Ortho-K, which stops wearing rear uncorrected visual acuity, no longer to be sprung back (or limited rebound), whole Body vision ability is significantly improved.

M5D light leads to the application method of mirror：

1st, M5D light lead to mirror be worn over auxiliary cornea it is moulding before there are one wear mirror impression, correction of refractive errors and load refractive state Laundering period and basic visual function optimization process.It is required that wearer during this period daily wear 2 it is small when (centre can rest 20 minutes), it closely becomes more meticulous with eye (eyes are no more than 33 centimeters with object distance).This stage, most of customers only needed Want can just complete within 2-3 weeks, certainly, if fruit part wearer fails to reach target, then this is worn mirror pattern is repeated once (one Week) or even repeat secondary.Successful standard is to wear to be obviously improved with basic adaptation and uncorrected visual acuity.

2. Ortho-K stops wearing time management：First stage：Adaptation and moulding phase, need 1-2 weeks (part wearer 2-3 weeks is needed, is subject to and wears mirror eyesight and uncorrected visual acuity all reaches more than 0.8), it wears and uses mode：When wearing 8 is small every night, this rank The section scope of examination includes wearing mirror eyesight, wearing mirror diopter, cum correction luminosity, plucks the corneal topography after mirror, corneal fluorescein Dyeing, uncorrected visual acuity, bore hole diopter are with most preferably correcting defects of vision.Second stage：Adjustment and consolidation, one month is needed, is worn Use mode：When wearing 10-12 is small every night, stop wearing the time as 2-3 days.In this stage, plucking more than 0.8 eyesight of the bore hole after mirror cannot tie up It holds 2 days, wearing need to be postponed 2 weeks with mode.Phase III：Training and optimization phase are, it is necessary to which one month, wears and use mode：Friday, When Saturday, Sunday continuous three evenings wearing 10-12 are small, the week stops wearing, and stops not wearing near-sighted glasses as far as possible during wearing.Fourth order Section：It is normal to wear with the phase, it wears and uses mode：Every time wear mirror 10-12 it is small when, and according to eyesight continued case select elasticity wear, general 7 It or so night wears once.

3rd, M5D light leads to mirror supplemental training and optimization：

1) wearer wears lead to mirror 120 minutes with M5D light every night that (reading in 60 minutes is done the homework, and is seen the mobile phone within 60 minutes or electricity Brain, distance are centainly maintained in 50 centimeters).Wearer, which can first wear to wear again after moulding mirror, uses up logical mirror, does not influence training effect.

2) close eye, within 50 centimeters (within best 33 centimeters).Pay attention to good sitting posture, head is not crooked, light Source brightness is moderate.

3) wearing time at least 120 minutes daily, property is worn enough 60 minutes at least once every time.The longer effect of wearing time is more It is good.Font of reading is the smaller the better, to see high pixel video.

4th, one group of mobile eyeglass is centainly allowed to be moved to after front end cannot move again, then adjusts back to initial position manually.

5th, wear and want energy concentration during use, emphasize to become more meticulous with eye, not change the distance of glasses and target arbitrarily.It cuts Avoid to shake the head or care for everywhere and see.

6th, M5D light leads to mirror because of dynamic refraction, does not have the negative interaction of other function glasses such as the asymptotic mirror of prism, multifocal, Use can be worn for a long time.

7th, some user's visual condition genetic prerequisites are bad, it is necessary to use the nutriments such as similar lutein, blueberry, protein Supplement.

M5D light leads to the scientific and technological principle of mirror：

It is well known that lasting close eye can cause adjusting to ossify, regulatory function declines, surrounding image mould can be caused Paste, the aggravation of peripheral hyperopia defocus, these are all an important factor for myopia is caused to occur, develop.What M5D light led to mirror wears use Person can realize a wide range of dynamic refraction of eyes in vision process, can generally change in -12.00D--+5.00D sections.Eyeball Information is provided for brain vision, is optics receiving organ.It not only services brain, is subject to brain.Brain possesses brain skin The ability of layer image optimization processing also includes error correction, compensation and sharpening to vision imaging and handles here, different two Angle, the picture of different clear situations synthesize image same, closer to complete true image.The certain journey of this capability improving Degree, will realize 1.0 under out-of-focus appearance, brain vision system is allowed to have, retina defocus information is effectively processed into brain skin Layer stablizes the ability of sharp image, so that it is guaranteed that uncorrected visual acuity can reach 1.0 or more than 1.0.

The utility model has the advantages that：Manual focusing can aid in Ortho-K reduction to wear image frequency rate, reduce complication, show It writes and improves focusing sensitivity, reduce intraocular biochemical change and myopia progression caused by muting sensitivity.
