Abstract

The utility model relate to an eyeglasses. Lens of current vision correcting eyeglasses (myopia and hyperopia) has the deficiencies as fixed shape of the lens ands limited adjustment of dioptre. In the utility model, the lens is divided into eyeglass and lens. The lens is made up of a pan bottom shape inner layer, an outer layer and a liquid layer. Rim of the pan bottom shape inner layer is provided with a lens edge which is bended outward and connected with the outer layer, forming a bedded liquid storage space with closed edge. Edge of the eyeglass is provided with a liquid passage. One end of the liquid passage is connected with the liquid layer, and the other end is connected with a hydraulic adjustment device which is arranged within edge of the eyeglass. When start the hydraulic adjustment layer, hydraulic pressure of the liquid layer increases, dioptre of concave lens decreases regularly and dioptre of convex lens increases. In contrast, the dioptre of the concave lens increases and the dioptre of the convex lens decreases so as to finish free adjustment of dioptre of the eyeglasses.

Description

The diopter tunable eyeglasses

(1) technical field: glasses based article.

(2) background technology: the existing general defective of correcting defects of vision (near, farsightedness) glasses.

(3) summary of the invention: in view of the existing general defective glasses of correcting defects of vision, its lens shape is fixed, the intensity of the defective of correcting defects of vision can not be regulated, be difficult to adapt to people near/the farsightedness number of degrees depth changes and watches the different distance object eyeglass diopter to be had the needs of different requirements, cause people have to eyeball near/variation of the hyperopia degree depth and constantly change glasses, perhaps when the near-sighted number of degrees are higher, dispose simultaneously and carry and see nearly (as read a book, write etc.) and sight two width of cloth glasses far away, and in use frequently use instead, put to no little inconvenience and waste.The purpose of this utility model will provide a kind of glasses exactly, and it can be in certain amplitude, and the end user that leaves does to be fit to the adjustment of needs at any time to the eyeglass diopter, not only convenient, but also saving.

Construction features of the present utility model and principle are: the lens component of eyeglass is designed to the bottom of a pan shape nexine, the three-decker of skin and liquid layer, there is a lens limit of outwards transferring and linking to each other with skin at the edge of the bottom of a pan shape nexine, utilize the transparency liquid printing opacity and in shape variable and the lens, layer distance that varies in size that design forms between the skin and the enclosure space that forms by the lens limit, form liquid layer by injecting transparency liquid, and make it to link to each other with hydraulic regulating device, make lens have the characteristic of two aspects: the one, the interfloor distance of different parts between the bottom of a pan shape nexine and the skin, can change with the variation of liquid layer pressure, the 2nd, the amplitude of this variation, practically negligible big more by edge to past more center, form the changeability of lens strength thus, promptly when liquid layer pressure strengthens gradually, the concavees lens diopter is by greatly gradually little, and the convex lens diopter is by little gradually big; Otherwise the concavees lens diopter is by little gradually big, and the convex lens diopter is by greatly gradually little.Realize the free adjustment of lens strength with this.

Because eyeglass of the present utility model, can not be as the eyeglass of existing general glasses, can interim the sanction cut setting with concrete condition such as user's interpupillary distance size, so between two lens frame, set up interpupillary distance regulating device, with the user's that adapts to different interpupillary distances needs based on the bispin bolt arrangement.

The mark of each several part shown in the accompanying drawing is: eyeglass 1, mirror holder 2, hydraulic regulating device 3, eyeglass limit 11, liquid-through hole road 111, lens outer ring groove 112, lens 12, the bottom of a pan shape nexine 121, outer 122, liquid layer 123, lens limit 124, lens frame 21, bispin bolt type interpupillary distance is regulated mobile jib 22, screw thread round bar 221, nut 222, interpupillary distance is regulated secondary bar 23, interior bar 231, outer tube 232, mirror holder leg 24, chamber body 31, liquid capsule squeezer rail groove 311, the inboard tooth engaged 312 of chamber wall, liquid capsule 32, liquid bag pressure sheet 33, liquid capsule squeezer 34, squeezer last slice 341, sphenoid 342, sphenoid tooth engaged 343.

(5) embodiment: technological core of the present utility model is that the dioptric liquid of lens (12) is regulated.Therefore, in manufacturing, (or also will thicken) suitably can be widened in the eyeglass limit (11) in two eyeglasses (1) outside, and the chamber body (31) of formation hollow, liquid-through hole road (111) in built-in liquid capsule (32) and the liquid bag pressure sheet (33), the Nang Kou of liquid capsule (32) and lens limit (11) links to each other, and opens rail groove (311) above the chamber body (31), one row's tooth engaged (312) is respectively arranged on the inwall of rail groove (311) both sides, and rail groove (311) is gone up and is embedded liquid capsule squeezer (34).When with liquid capsule squeezer (34) forward impelling, its sphenoid (342) promptly acts on liquid bag pressure sheet (33), and remake by liquid bag pressure sheet (33) and to be used for liquid capsule (32), make the liquid layer (123) of the past lens (12) of partially liq pressure in the liquid capsule (32), the fluid pressure (volume) of liquid layer (123) is strengthened, and then the change that varies in size of the thickness that makes lens (12) different parts, realize the dioptric free adjustment of lens (12) thus.

For making the existing certain steadiness of eyeglass (1), enough adjusting sensitivity is arranged again, it is gradually thick outward the skin (122) of lens (12) can be made from central division the position, and the bottom of a pan shape nexine (121) is made the thin layer of uniform thickness, is subjected to the general gauffer that do not occur when wiping touching as long as guarantee it.Wherein each layer thickness of concavees lens distributes suggestion to be: the bottom of a pan shape nexine (121) 0.3-0.5 millimeter, outer (122) centre 0.5-0.7 millimeter, liquid layer (123) centre original depth 0.2-0.3 millimeter, gross thickness 1-1.5 millimeter.
