Abstract

The utility model relates to a five-hole glasses for correcting the myopia, which is a tool having the same character with the glasses for protecting eyes and correcting the vision. Shading supports fixed on ears or the head is provided with hard light-tight perspective pieces with small pores in the front of both eyes. The small pores of the perspective pieces are preferably five crosses which are symmetrically arranged on the position with different angles corresponding to both eyes. The utility model has the advantages of easy fabrication, low cost. Users use the utility model can obviously improve the eyesight. The utility model can reduce the astigmatism degree of the patient without any side effects.

Description

Five-hole glasses for correcting myopia

This utility model relates to a kind of apparatus of correcting defects of vision with the protection eyes of the same characteristics of glasses that has.

The method of existing correction of myopia has multiple, and its curative effect all can not be affirmed.Its formation of control glasses for the myopia (notification number 86200964) at No. 2 bulletin of utility model patent communique the 3rd volume is established hyperopic lens below goggles or concave lens, the glasses of this band eyeglass exist with the same disadvantage of other glass glasses, as price height, fragile, meet cold or meet heat affecting sight line etc.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the apparatus of rescuing vision that a kind of non-glass eyeglass is provided.

The purpose of this utility model can reach by following measure: a kind of five-hole glasses that adopts the physical method correction of myopia, it has a shading support that can be fixed on ear or the head, and the support that it is characterized in that being positioned at eyes the place ahead is provided with narrow meshed lighttight hard and looks sheet.The purpose of this utility model can also reach by following measure: look on the sheet and be provided with the aperture of five decussation symmetric arrays with two corresponding positions at light tight hard.

This utility model is by looking sheet and support is formed.Looking sheet is lighttight hard plate, it can be plastic plate of hardboard, non-printing opacity etc., and they are black preferably.Can establish two apertures on the sheet looking, i.e. the aperture in every eyes front.The diameter in this hole is 0.5～1 millimeter, is preferably 0.75 millimeter.But because people's interpupillary distance variant (generally between 50～70 millimeters), be offset up and down for adapting to everyone different interpupillary distance and wearing the time spent, then around each aperture, set up four same apertures again, be that 60 millimeters aperture is the center promptly with two spacings, four direction is all respectively established an aperture for 5 millimeters in the interval up and down, makes them be the decussation symmetric arrays.Make that like this common people's pupil is always corresponding with certain two aperture wherein, to look object.Support is made with plastics or plastic material, and the framework of good shaded effect is arranged.It can be that the support similar to frame is worn on the ear, also can be to utilize the flexible fastening of its material itself on head.The support that is positioned at eyes the place ahead is provided with narrow meshed lighttight hard and looks sheet, and this looks sheet can be that what to be connected as a single entity with support also can be to place in the set clamping device of support.

This utility model is not with any diopter, utilizes the depth of field to increase view principle and designs.Wear and to promote bathomorphic vision behind this mirror and see that far object is clear, in order to reach the lax purpose of regulating and rescuing vision.

This utility model manufacturing is simple, cheap, wears with the back vision and obviously improves, and also can alleviate patient's astigmatic degree, and without any side effect.

The utility model is described in further detail to utilize the example shown in the accompanying drawing.

Fig. 1 is a three-plane projection of the present utility model sketch map.

Fig. 2 is a schematic perspective view of the present utility model.

In the correction of myopia five-hole glasses shown in Figure 1, look on the sheet 2 at black hardboard rectangle, be provided with the aperture 3 of five decussation symmetric arrays with two corresponding positions, its aperture is 0.75 millimeter.The distance of two central small hole is 60 millimeters, and four apertures are 5 millimeters to the distance of central small hole on every side.This is looked sheet and is inserted in the upper ledge on the support neutral gear that is arranged in eyes the place ahead and the groove 5 of lower frame.The dark opaque-plastic of this support 1 usefulness is made.Upper and lower side frame be equipped with inwardly turn over along 4, and the bracket end of looking the sheet both sides is with less than the radius of curvature inflection of head as shown in Figure 2.

Claims

1, a kind of five-hole glasses that adopts the physical method correction of myopia, it has a shading support 1 that can be fixed on ear or the head, it is characterized in that: the support that is positioned at eyes the place ahead is provided with is with the lighttight hard of aperture 3 to look sheet 2.

2, the correction of myopia five-hole glasses according to claim 1 is characterized in that: look on the sheet and be provided with the aperture of five decussation symmetric arrays with two corresponding positions at light tight hard.
