Abstract

The utility model relates to a spectacle for astigmatism remedy; the opaque glass is disposed with many tapered penetrating holes whose external circle diameter is less than the internal circle diameter, moreover, the inclination of tapered penetrating holes on the opaque glass near the brim is larger and larger from the center to the brim which enables users will not be blocked when they watch external things through the tapered penetrating holes and the focalizing function could be achieved with this model which will make users not produce the vision dead angle and blind point, therefore, this model is more pragmatic.

Description

The astigmatism correction glasses
Technical field
The utility model refers in particular to a kind of making and wears the user that it is used for carrying out astigmatism relevant for a kind of astigmatism correction glasses, obtains better focusing effect in the use, and can more increase the astigmatism correction glasses of its practical effect characteristic.
Background technology
Astigmatism promptly is so-called " disorderly looking ", it is not positive a kind of of eye refraction, the flexion face that mainly is meant the dioptric system (cornea and crystalline) of eyeball is not the smooth surface of sphere shape, make the parallel light in a distant place on retina, can't be focused into a point clearly, but loose into different images.
General astigmatic phenomenon is when correcting, mainly be to wear the glasses of correcting usefulness, these glasses as shown in Figure 9, a plurality of cylindricality perforations 21 on light tight eyeglass 2, have been opened, this cylindricality perforation 21 can be cylindrical or hexagonal cylindricality etc., when making the user outwards watch object, can allow light on retina, be focused into a point clearly smoothly, and obtain the effect of correcting by each cylindricality perforation 21 of this light tight eyeglass 2.
Yet, though above-mentioned astigmatism correction glasses can reach the expection effect of its astigmatism, but also in its actual use, find, because the cylindricality perforation on the light tight eyeglass of these glasses all is the identical long column shape in two ends week footpath, and this light tight eyeglass is bending arc shape for cooperating face's curve, make when the user outwards watches object by being distributed in light tight eyeglass each cylindricality perforation on every side, its sight line is very easily blocked by the cylindricality perforation, and cause focusing effect not good, easily produce blind spot, dead angle in visually, cause its very big inconvenience in the use.
Summary of the invention
The purpose of this utility model is to provide a kind of astigmatism correction glasses, when the user uses these glasses to watch object, can increase the focusing effect, and its sight line can not be blocked, and can not produce visual dead angle, blind spot.
The purpose of this utility model is achieved in that a kind of astigmatism correction glasses, and these glasses mainly are to be respectively equipped with corresponding neither transmission lens on mirror holder, and are provided with corresponding foot rest all to the back-end in these glasses both sides; Opened a plurality of taper perforations on this light tight eyeglass, the outboard end Zhou Jing of this taper perforation is less than medial extremity Zhou Jing, and on this light tight eyeglass by the taper perforation of center toward the approaching more light tight eyeglass periphery of periphery, its lopsidedness angle that relies on periphery is big more.
By the above, the utility model is compared with existing structure, because the utility model is opened the many taper perforation of medial extremity Zhou Jing greater than outboard end Zhou Jing on each light tight eyeglass of glasses, and on this light tight eyeglass by the center toward the taper perforation of the approaching more light tight eyeglass periphery of periphery, its lopsidedness angle that relies on periphery is big more, make when the user outwards watches various object by the taper perforation, it can obtain better focusing effect, sight line can not produce dead angle, blind spot, can increase practical value really.

Embodiment
At first, see also Fig. 1~shown in Figure 3, the utility model is used for the glasses 1 of astigmatism, and it is to be respectively equipped with corresponding neither transmission lens 12 on mirror holder 11, and is provided with corresponding foot rest 13 all to the back-end in these glasses 1 both sides; Wherein:
A plurality of taper perforations 121 have been opened on this light tight eyeglass 12, the outboard end Zhou Jing of this taper perforation 121 is less than medial extremity Zhou Jing, and please consult Fig. 4~shown in Figure 7 more in the lump, each taper perforation 121 of being opened on this light tight eyeglass 12 is arranged diffusion by central point toward left and right horizontal direction and upper and lower vertical direction, it is toward the taper perforation 121 of approaching more light tight eyeglass 12 peripheries of periphery, its lopsidedness angle that relies on periphery is more for strengthening (as shown in the figure, tiltangle 2 is greater than θ 1), can adapt to human eyeball's focusing visual angle.
Thus, please consult shown in Figure 8 again, the user is in using these glasses 1 to carry out the rectification of astigmatism, when outwards watching various object by each taper perforation 121 of this light tight eyeglass 12, when the field-of-view angle of user's eyeball by central point when horizontal direction or vertical direction are launched, can assist astigmatic user can increase the focusing effect fast by the variation at the periphery angle of inclination of each taper perforation 121 to reduce the phenomenon of astigmatic image, make user's sight line can not produce dead angle, blind spot.
