Abstract
The utility model discloses a double-focus lens, comprising a lens, frame and lens legs. The utility model comprises two sets of lenses and two sets of connection mechanisms between the two sets of lenses. The utility model is characterized in that the utility model can prevent and cure myopia, and automatically regulate a focal length, both near and distant objective images can be clearly viewed, the lenses are conveniently selected and matched, and the utility model which is worn on eyes is relatively beautiful.
Description
The utility model relates to a kind of glasses, and it is a kind of bifocus mirror of automatic focusing.
In the bifocus mirror in prior art, mainly contain bifocus presbyopic glasses, Liu east physiotherapeutic glasses, win type such as formula bifocus mirror.The latter half of the eyeglass of bifocus presbyopic glasses comprises the oval-shaped normal position of spherical lens of a fritter, and remainder is less relatively normal position of spherical lens of the number of degrees or negative concave-sphere.The bifocus presbyopic glasses can alleviate the fatigue of eyes to a certain extent, but looking near or to look under the situation far away its visual field all less, and its eyeglass and common eyeglass disunity, apolegamy eyeglass inconvenience, in addition, because the eyeglass of two kinds of focuses coexists as same plane, it is possible all that sight line sees through from any part of eyeglass, so can cause unnecessary visual fatigue; Liu east physiotherapeutic glasses is to be made of the Micropole glasses of the first half and the normal position of spherical lens of Lower Half.The Micropole glasses of its first half is equivalent to negative concave-sphere, so Liu east physiotherapeutic glasses also is a kind of bifocus mirror, also can looks the people and alleviates forward when near and regulate burden, looks to alleviate the negative regulation burden when far away.But it has following shortcoming; 1, look near or look half that can only utilize eyeglass when far away, the visual field is little.2, pinhole imaging system.See through into the insufficient light in the eyes, than lens imaging, the visual field has been blured many.3, the first half is a black, is worn on the eyes not attractive in appearance.4, be inconvenient to change eyeglass, can not make the A nearsighted person of different myopic degrees all reach the calibration result an of the best; The bifocus mirror that can win at any time is to look when near with convex lens, looking and use concavees lens when far away, clear visual field, but very inconvenient, impracticable.
The purpose of this utility model provide a kind of development that can control myopia can make again look near, look image far away all very clearly, be convenient to produce and match both artistic and practical bifocus mirror eyeglass, that can focus automatically.
The utility model is achieved in that it comprises the structures that common spectacles had such as picture frame, mirror leg, and main points are that it is provided with bindiny mechanism between two set of contact lenses and two set of contact lenses.Two set of contact lenses comprise preceding mirror 1 that two concavees lens are formed and the back mirror of being made up of two convex lens 2.Axle 4 of upper limb transverse weld of preceding mirror 1, axle 4 injects the axle sleeve 5 that weldering is connected in back mirror 2 upper limbs.Axle 4 is connected with axle sleeve 5 wants degree of tightness suitable, and can not about dislocation, preceding mirror 1 and after mirror 2 with the different correspondences of myopic degree the different lens number of degrees make up.Fig. 1 is an oblique view of the present utility model.Fig. 2, Fig. 3 are respectively the utility model and are looking far away and looking the side view of nearly two kinds of situations.Looking when far away, preceding mirror is adjusted to negative concave-sphere or the lower normal position of spherical lens of the number of degrees because action of gravity is overlapping with the back mirror.Looking when near, because the inclination of back mirror, and the not hypsokinesis under action of gravity of preceding mirror, preceding mirror separate with the back mirror, and sight line is by the back mirror and since after mirror be normal position of spherical lens, so can alleviate the forward adjusting burden of eyes.The utility model also can be set up a mirror position stabilizing mechanism: the central authorities' weldering at axle 4 connects a cam 6, and the spring leaf 7 that is connected back mirror 2 picture frame central authorities contacts with cam 6.Fig. 4 is the side view of cam 6.This mechanism helps after eyeglass is stabilized in circle 2 or the position of Fig. 3 eyeglass both to make to be subjected to any to rock, and its relative position does not change yet, and makes image stabilization.
Advantage of the present utility model is: 1, prevent the overtired of eyes, that suppresses myopic degree further adds class.2, focus automatically, look near and to look image far away all very clear; Study and work is all very convenient.3, use common eyeglass, the apolegamy eyeglass is very convenient, can be equipped with different eyeglasses according to the difference of myopic degree.4, all form, do not have the black shelter, be worn over better appearance on the eyes by lens.
Claims (4)
1, a kind of bifocus mirror, it comprises mirror leg, picture frame, it is characterized in that: have the bindiny mechanism between two set of contact lenses and two set of contact lenses.
