Abstract
The utility model relates to a pair of plano-presbyopic dual-purpose glasses, composed of a spectacle frame, a left lens and a right lens, wherein, the left lens is formed by the method that a sphere-shaped plano lens and a flat plano lens are folded upper and lower, a convex lens-shaped sealed cavity is formed in the middle part, circulation holes are arranged on the inner side of the cavity, the right lens is formed by the method that a flat plano lens and a convex lens sheet are folded upper and lower, a concave lens-shaped sealed cavity is formed in the middle part, circulation holes are arranged on the inner side of the cavity, a gas adjustment liquid cavity is arranged between the left lens and the right lens, plugs are arranged in the circulation holes, adjustment liquid is arranged in the concave sealed cavity, and gas is filled in the concave sealed cavity. The utility model has the advantages of simple structure, convenient production and quick variations of functions, and the utility model has the characteristic that the pair of glasses can be used widely.
Description
The utility model relates to a kind of optical devices, especially a kind of zero diopter-presbyopic Dual-purpose glasses.
Along with people's age growth, the elderly's vision is constantly changing, and the eyes that just it has often been said " presbyopic " need be worn presbyopic glasses and regulate eyes Qu Guangdu, just can see thing clearly.Existing presbyopic glasses are divided into two kinds usually, and a kind of is the presbyopic glasses of function singleness, and another kind is that half is replaced as presbyopic lens under the plano lens, the former needs constantly to put on or take in actual use, and is poor to environmental suitability, trouble, the latter has tunnel vision, the extremely inconvenience of walking of going out.
The purpose of this utility model is the deficiency that exists at prior art and design a kind of function and change, go out accommodating, visual field expansion fast, do not need the zero diopter one presbyopic Dual-purpose glasses taken back and forth, has the multiple function of safety goggles, goggles, presbyopic glasses.
The purpose of this utility model is achieved in that a kind of zero diopter-presbyopic Dual-purpose glasses, it is made of mirror holder and left and right sides eyeglass, it is characterized in that left eyeglass is formed by stacking up and down by the sphere shape plano lens of anter and the planar shaped plano lens of rear panel, middle formation is convex lens shape annular seal space, and the annular seal space inboard is provided with opening; Right eyeglass is formed by stacking up and down by the planar shaped plano lens of anter and the convex lens sheet of rear panel, and middle formation is concavees lens shape annular seal space, and the annular seal space inboard is provided with opening; Be provided with gas-liquid between the eyeglass of the left and right sides and regulate the chamber, regulate the chamber and be communicated with convex lens shape annular seal space and concavees lens shape annular seal space through opening; Be provided with the obstruction that can slide up and down in the opening, Qu Guangdu be housed in its convex lens shape annular seal space adjust liquid, be filled with gas in the concavees lens shape annular seal space, vice versa.Its principle of work: adjust liquid if inject transparent Qu Guangdu in the convex lens shape annular seal space of left side, because of liquid has refraction action, so it is a moulding liquid convex lens that the left side annular seal space becomes, then left eyeglass becomes convex lens, be commonly called as presbyopic glasses, and still be gas in the concavees lens shape annular seal space of right side, so right eyeglass still is a convex lens, add the radian of annular seal space on the left of making man-hour and the number of degrees of right eyeglass rear panel convex lens and conform to the number of degrees of joining the mirror eye, then this mirror can be used as the presbyopic glasses use; If the liquid in the left chamber is introduced in the right chamber, gas in the then right chamber enters in the left chamber, unnecessary gas-liquid can be stored in regulates in the chamber, and then right-side cavity becomes moulding liquid concavees lens, adds the radian of selecting right eyeglass anter goggles man-hour, the effect and the effect of rear panel convex lens of liquid concavees lens are offset, then right eyeglass is a goggles, and the left side annular seal space contains gas, so left eyeglass still is a goggles, this mirror promptly becomes one pair of goggles use so, thereby reaches the dual-purpose purpose of a mirror.
The utility model modern design, simple in structure, operation has the advantages that a mirror is used more fast during use, and suitable the elderly wears, the long journey of being convenient to go out.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the cross-sectional synoptic diagram of the utility model embodiment 1 left and right sides eyeglass.
Fig. 3 is the cross-sectional synoptic diagram of the utility model embodiment 2 left and right sides eyeglasses.
Shown in Fig. 1～2, a kind of zero diopter-presbyopic Dual-purpose glasses, it is made of mirror holder (1) and left and right sides eyeglass (2,3), its left eyeglass (2) is overlapped into up and down by the sphere shape plano lens (4) of anter and the planar shaped plano lens (5) of rear panel, middle formation is convex lens shape annular seal space (6), and annular seal space (6) inboard is provided with opening (7); Right eyeglass (3) is overlapped into up and down by the planar shaped plano lens (8) of anter and the convex lens sheet (9) of rear panel, and middle formation is concavees lens shape annular seal space (10), and annular seal space (10) inboard is provided with opening (7); Be provided with gas-liquid between the left and right sides eyeglass (2,3) and regulate chamber (11), regulate chamber (11) and be communicated with convex lens shape annular seal space (6) and concavees lens shape annular seal space (10) through opening (7); Be provided with the obstruction (12) that can slide up and down in the opening (7), Qu Guangdu be housed in its convex lens shape annular seal space (6) adjust liquid (13), be filled with gas in the concavees lens shape annular seal space (10).Use: when being gas in being full of Qu Guangdu adjustment liquid (13), concavees lens shape annular seal space (10) in the convex lens shape annular seal space (6), these glasses use as presbyopic glasses.If wanting to transform into goggles uses, earlier the glasses upper frame is gently knocked downwards, stop up (12) and break away from opening (7), regulate chamber (11) and two annular seal spaces (6,10) be communicated with, when being housed, adjustment liquid sealing chamber (6) upwards falls gently, adjust liquid (13) through opening (7), regulate chamber (11), opening (7) slowly flows in the right side annular seal space (10), gas in the chamber (10) is pressed in the left side annular seal space (6), when being full of two annular seal spaces (6,10) after, unnecessary gas-liquid is stored in gas-liquid and regulates in the chamber (11), crack down obstruction (12) sealing between the teeth, two annular seal spaces (6,10) Nei gas-liquid is no longer mobile mutually, and this moment, glasses became the goggles use.Use if want to revert to presbyopic glasses, only need reverse operating to get final product.If the old man also need wear presbyopic glasses when walking at ordinary times, there is depth difference in the presbyopic glasses number of degrees during with reading, then left and right sides eyeglass (2,3) can be designed to as shown in Figure 3, the anter of its left and right sides eyeglass (2,3) is convex lens sheet (14), and two convex lens sheets (14) are different with the presbyopic number of degrees of right eyeglass (3) rear panel convex lens sheet (9).
