Among the figure: 1,10 eyeshields, 2,20,201,202 tracheas, 3,30 action devices, 31 shells, 32 control knobs, 33 powered rotation bodies, 34 speed change parts, 340 runners, 35 eccentric runners, 350 connecting rods, 351 take turns diameter and arc surface, 350 ' pivoting point, 36 rotors, 37 push rods, 38,360 air chambers, 370 control panels, 371 guide pillars, 372 grooves, 39 elastic springs, 40 adjusting knobs, 50 controllers, 60 electromagnetism relief valves, 61 openings, SW1, SW2 touch switch.

Referring to Fig. 2,3; This utility model embodiment 1 includes: eyeshield 10 is two symmetrical covers, and there have adhesive tape can be nested with on head to be fixing, and the cover downside connects trachea 20.Trachea 20 is a hose body, is the body of gas advance and retreat between action device 30 and the eyeshield 10.Action device 30 has a shell 31, there are several control knobs 32 on the surface, control knob 32 is divided into release knob, just, the counter-rotating control knob, the control knob of regulating the speed, regulate control knob with the time, and have a power running body 33 to drive speed change parts 34 in the shell 31, running power running body 33 is rotation motors, control motor running speed by the control knob of regulating the speed, and just, counter-rotating control knob control motor forward or reverse, whether the on-off control button then controls running, wherein power running body 33 imports power into speed change parts 34, and import power on the axle eccentric runner 35 by the outputting power axle by speed change parts 34, rotor 36 on eccentric runner 35 running hour wheel diameter and arc surfaces 351 begins to rotate (Fig. 4), because eccentric runner 35 clockwises running, so the push rod 37 on the rotor 36 makes air chamber 38 make expanding-contracting action, the expanding-contracting action of air chamber 38 is as " fast pressure is put slowly ", to treat myopia simultaneously; And when eccentric 35 is turned round with inverse clock by the action of power running body 33 (Fig. 5), the expanding-contracting action of air chamber 38 drawn stems 37 then is that " press slowly and put soon " is with the treatment hypermetropia.As make the expanding-contracting action of air chamber 38 quicker, in air chamber 39, be provided with elastic spring 39, to protrude out the auxiliary of action as air chamber 38; Wherein when push rod 37 (Fig. 6) is subjected to eccentric runner 35 actions flexible, the guide pillar that the bottom surface was convexly equipped with 371 of push rod 37 is to slide in tongue 372 with the flexible of push rod 37, make push rod 37 be subjected to eccentric runner 35 compel to push away the time, unlikely generation skew and then make the action of air chamber 38 accurately flexible.

As shown in Fig. 7-9 embodiment 2; Shell 31 surfaces of action device 30 are provided with several control knobs 32, control knob 32 is divided into a release knob, just, the counter-rotating control knob, regulate the speed control knob and time is adjusted control knob, shell 31 inside are then established a power running body 33 and are driven a runner 340 runnings, power running body 33 is an inverter motor, and control the inverter motor running speed by the control knob of regulating the speed, and just, counter-rotating control knob control inverter motor forward or reverse, whether the on-off control button then controls running, wherein power running body 33 is to import power into runner 340, runner 340 articulates a connecting rod 350, connecting rod 350 is connected an air chamber 360, and between runner 340 and power running body 33, establish a control panel 370, the plate face is arranged with two relative touch switch SW1, SW2, turn round when power running body 33 drives runner 340 with clockwise, connecting rod 350 pivoting points 350 ' of runner 340 belows urge touch switch SW1 in advance; Touch switch SW1 controls its power running body 33 generation frequency conversions and quickens to improve its revolution speed with moment, make speeding up of connecting rod 350 tensions, and return back to touch switch SW1 in when urging when pivoting point 350 ', then making its power running body 33 produce frequency conversion again slows down, it is fast to relax its revolution with moment, the speed that push rod 350 is pushed away is slow, makes 360 effects of 350 pairs of air chambers of connecting rod form " fast pressure is put slowly " to treat myopia like this; And when power running body 33 turns round with inverse clock, then can make 360 effects of 350 pairs of air chambers of connecting rod form " press slowly and put soon " with the treatment hypermetropia.

As shown in figure 10; On the trachea 20 of eyeshield 10 lower sides, be provided with two gas flow modulation buttons 40, control the required difference of air pressure size that is entered in two eyeshields 10 with the rotation of adjusting knob 40, to treat two problems that the gap number of degrees are excessive.

As shown in Figure 11 embodiment 3; On action device 30, establish a controller 50, and connect an electromagnetism pressure relieving valve 60 with trachea 201, and connect trachea 20 by another trachea 202, after powered rotation body 33 is pulled to maximum space with air chamber 360 by connecting rod 350, when extruding produces malleation forward again (treatment myopia), controller 50 makes gas pass through electromagnetism pressure relieving valve 60, make the air pressure eyeshield 10 that all leads, and the negative pressure that when air chamber 360 is subjected to connecting rod 350 post-tensionings, is produced, controller 50 makes the opening 61 uncovered suction ambient atmos of electromagnetism pressure relieving valve 60, make no negative pressure appearance generation in the eyeshield 10, making counteragent by this reason then is the effective malleation of negative pressure invalid (controlling hypermetropia), by trachea 202 with baroreflex at controller 50, make controller 50 action electromagnetism relief valves 60, discharging malleation, the gas when the excessive and negative pressure of normal pressure is excessive is by opening 61 dischargings, and reaches correct positive/negative pressure.
