Abstract
Glasses of the invention comprise lenses; each lens comprises an upper vision zone, a lower vision zone, a left vision zone and a right vision zone, wherein the lens diopters of the left vision zone and the right vision zone are both 0 D. Compared with conventional glasses, the glasses of the invention are provided with a distance-vision zone and a near-vision zone, and solve the problem that the conventional glasses cannot have functions for both distance vision and near vision; and the glasses of the invention are provided with 0 D zones in two sides, and solve the prism effect problem of multifocal progressive glasses.
Description
Technical field
The present invention relates to a kind of glasses, particularly a kind of novel and can the glasses of anti-fatigue.
Background technology
In myopia crowd, great majority are teenagers, and the general method wearing common spectacles that adopts is corrected defects of vision, and after lens-induced myopia wears glasses, myopic degree is often caused to increase the weight of year by year, can be near depending on far looking again this is because use common concave lens a pair of glasses to accomplish.
In addition, for current multifocal Progressive addition lens on the market, its weak point is the visual fatigue drawback that the prism effect caused due to lens radian when glasses wearer sees to both sides time brings to glasses wearer.
Therefore, common spectacles do not solve to be seen and closely sees problem far away, and but multifocal Progressive addition lens solves this problem there is other wretched insufficiency and prism effect.And the present invention is in conjunction with the actual use habit of human eye, design the deficiency that problem that namely more rational double focus lens chip architecture solve common near-sighted glasses turn avoid multifocal Progressive addition lens, simultaneously relatively simple again in technique, there is good practical function.
Summary of the invention
The present invention be directed to existing lens design and eyes use the problem be not inconsistent, propose a kind of glasses, far field and near reading range is looked by arranging, 0D region is set in bifocal slasses both sides vision area simultaneously, then solve common spectacles not solve and see and closely see problem far away, also solve multifocal Progressive addition lens prism effect problem.
Technical scheme of the present invention is: a kind of glasses, comprise eyeglass, and described eyeglass comprises four, upper and lower, left and right vision area, and the eyeglass number of degrees of described left vision area and described right vision area are 0D.
In an embodiment of the present invention, the described upper vision area with the first focus and the described lower vision area with the second focus respectively have fixing len number of degrees and the absolute value of the eyeglass number of degrees of described upper vision area is more than or equal to the eyeglass number of degrees of described lower vision area.
In an embodiment of the present invention, described upper vision area and described lower vision area arrange for axle center and according to the diopter of eyesight with the meridian of eyeglass, to be formed as looking upper the vision area in far field and the lower vision area as near reading range.
In an embodiment of the present invention, the eyeglass range of degrees of described upper vision area is-2.00D to-15.00D.
In an embodiment of the present invention, the eyeglass range of degrees of described lower vision area is-0.5D to-6.00D.
Beneficial effect of the present invention is: the anti-tired eyeglass of bifocus of the present invention, far field and near reading range is looked by arranging on eyeglass, 0D region is set in the both sides vision area of ultex of the present invention simultaneously, make the present invention except having superiority with common near-sighted glasses contrast, more this outstanding part is exactly for current multifocal Progressive addition lens.The weak point of multifocal Progressive addition lens is the visual fatigue drawback that the prism effect caused due to lens radian when glasses wearer sees to both sides time brings to glasses wearer.And there is 0D region the anti-fatigue eyeglasses both sides of bifocus of the present invention, just avoid the weak point of multifocal spectacles.
Therefore, see closely see problem far away because common spectacles does not solve, but multifocal Progressive addition lens solves this problem there is other wretched insufficiency and prism effect.And the problem that namely the anti-tired lens structure of bifocus of the present invention solves common near-sighted glasses turn avoid the deficiency of Progressive addition lens, simultaneously relatively simple again in technique.

Fig. 1 is the schematic diagram of glasses of the present invention;
Embodiment
The anti-tired eyeglass of bifocus of the present invention is compared with multifocal Progressive addition lens, difference is that the present invention is provided with the left and right vision area that the eyeglass number of degrees are 0D on eyeglass, so when eyes see the left side or the right object time, just need head to turn round, doing so avoids the visual fatigue drawback that the prism effect that causes due to lens radian time glasses wearer sees to both sides brings to glasses wearer.In addition compared with common near-sighted glasses, difference is that the present invention is provided with on eyeglass and looks far field and near reading range, and solution is seen and closely seen problem far away.Therefore the present invention considers to design ultex from the actual use habit of human eye, for correcting retina left and right sides vision area out of focus, and effectively controls the development of the myopia number of degrees.
Fig. 1 is the schematic diagram of glasses of the present invention, as shown in the figure.On one piece of anti-tired eyeglass of bifocus, for axis, eyeglass is set to upper vision area 1, lower vision area 2, left vision area 3, right vision area 4 four vision areas with the meridian 5 of eyeglass.Wherein as looking upper the vision area 1 in far field and being bifocus vision area as the lower vision area 2 of near reading range, left vision area 3 is 0D with the eyeglass number of degrees of right vision area 4.
Ultex refers to makes different flexibility in the upper vision area of a lens and lower vision area, see nearby time standby under vision area, when seeing at a distance by vision area.
In one embodiment of the invention, the upper vision area 1 with the first focus and the lower vision area 2 with the second focus respectively have fixing len number of degrees and the eyeglass number of degrees of upper vision area 1 are more than or equal to the eyeglass number of degrees of lower vision area 2.Such as, the eyeglass range of degrees of upper vision area 1 is-2.00D to-15.00D, and the eyeglass range of degrees of lower vision area 2 is-0.5D to-6.00D.Certain eyeglass number of degrees of the present invention carry out arranging according to the diopter of eyesight, is not limited to above-mentioned eyeglass range of degrees.
In one embodiment of the invention, upper vision area 1 and lower vision area 2 are axle center with the meridian 5 of eyeglass and arrange according to the diopter of eyesight, to be formed as looking upper the vision area in far field and the lower vision area as near reading range, because those skilled in the art know, therefore no longer describe in detail.
No matter the present invention is ultex is injection mo(u)lding, realizes without splicing vestige in eyeglass, specious.Ultex of the present invention can set up two pieces of eyeglasses on the eyeglass that the eyeglass number of degrees are 0D, and is combined by two pieces of eyeglasses, sees far away for one piece, sees near for one piece.Certain the present invention can also be realized by other manufacture method, but is not limited thereto.
In sum, because the eyeglass number of degrees in left and right vision area are set to 0D, when eyes see the left side or the right object time, just need head to turn round, can regulate glasses load as much as possible and alleviate glasses fatigue, effectively controlling the myopia number of degrees increases.Further, the present invention also arranges and looks far field and near reading range, solves glasses wearer well and sees and far see near problem.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.These, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
