Among the myopia crowd, great majority are teenagers, and the general method of wearing common spectacles that adopts is corrected defects of vision, and after lens-induced myopia wears glasses, tend to cause myopic degree to increase the weight of year by year, this is can look far again closely because use common concave lens a pair of glasses can't accomplish to look.

In addition, for present multifocal some Progressive addition lens on the market, its weak point is when the glasses wearer sees to both sides because the visual fatigue drawback that the prism effect that lens radian causes brings to the glasses wearer.

Therefore, common spectacles do not have to solve to be seen and closely sees problem far away, and multifocal some Progressive addition lens solved this problem but existing other wretched insufficiency is prism effect.And the utility model is in conjunction with the actual use habit of human eye, designs the deficiency that problem that more rational double focus lens chip architecture namely solved common near-sighted glasses has been avoided again multifocal some Progressive addition lens, and is relatively simple again on the technique simultaneously, has preferably practical function.

The utility model content

The utility model is to use the problem that is not inconsistent for existing lens design and eyes, a kind of glasses have been proposed, look far field and near reading range by setting, simultaneously in bifocal slasses both sides vision area the 0D zone is set, then having solved common spectacles does not have to solve and sees and closely see problem far away, has solved multifocal some Progressive addition lens prism effect problem yet.

The technical solution of the utility model is: a kind of glasses, comprise eyeglass, and described eyeglass comprises four vision areas in upper and lower, left and right, the eyeglass number of degrees of described left vision area and described right vision area are 0D.

In the utility model one embodiment, the described lower vision area that has the described upper vision area of the first focus and have the second focus respectively has the absolute value of the eyeglass number of degrees of fixing len number of degrees and described upper vision area more than or equal to the eyeglass number of degrees of described lower vision area.

In the utility model one embodiment, described upper vision area and described lower vision area are that meridian take eyeglass arranges as the axle center and according to the diopter of eyesight, to form as the upper vision area of looking the far field with as the lower vision area of near reading range.

In the utility model one embodiment, the eyeglass number of degrees scope of described upper vision area is-200D is to-1500D.

In the utility model one embodiment, the eyeglass number of degrees scope of described lower vision area is-50D is to-600D.

The beneficial effects of the utility model are: bifocus described in the utility model is prevented tired eyeglass, by looking far field and near reading range eyeglass setting, simultaneously in the both sides of ultex described in the utility model vision area the 0D zone is set, so that the utility model except having superiority with common near-sighted glasses contrast, should outstanding part be exactly for multifocal present Progressive addition lens more.The weak point of multifocal some Progressive addition lens is when the glasses wearer sees to both sides because the visual fatigue drawback that the prism effect that lens radian causes brings to the glasses wearer.And there is the 0D zone the anti-fatigue eyeglasses both sides of bifocus described in the utility model, have just avoided the weak point of multifocal spectacles.

Therefore, because common spectacles have to solve and see and closely do not see problem far away, multifocal some Progressive addition lens solved this problem, and still to exist other wretched insufficiency be prism effect.And the problem that the anti-tired lens structure of the utility model bifocus has namely solved common near-sighted glasses has been avoided the deficiency of Progressive addition lens, and is relatively simple again on the technique simultaneously.

Embodiment

The anti-tired eyeglass of bifocus described in the utility model is compared with multifocal some Progressive addition lens, difference is that the utility model is provided with the left and right sides vision area that the eyeglass number of degrees are 0D at eyeglass, so when eyes are seen the left side or the right object, just head need to be turned round the visual fatigue drawback that the prism effect that has caused owing to lens radian when so just having avoided the glasses wearer to see to both sides brings to the glasses wearer.Compare with common near-sighted glasses in addition, difference is that the utility model looks far field and near reading range eyeglass being provided with, and solves to see and closely see problem far away.Therefore the utility model considers to design ultex from the actual use habit of human eye, is used 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 described in the utility model, as shown in the figure.On the anti-tired eyeglass of a bifocus, be set to upper vision area 1, lower vision area 2,

left vision area

3,4 four vision areas of right vision area take the meridian 5 of eyeglass as the axis eyeglass.Wherein be the bifocus vision area as the upper vision area 1 of looking the far field with 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 make different flexibility in the upper vision area of a lens with lower vision area, see nearby the time standby under vision area, use vision area when seeing at a distance.

Among the embodiment of the present utility model, the upper vision area 1 with first focus respectively has the eyeglass number of degrees of fixing len number of degrees and upper vision area 1 more than or equal to the eyeglass number of degrees of lower vision area 2 with the lower vision area 2 with second focus.For example, the eyeglass number of degrees scope of upper vision area 1 is-200D is to-1500D, the eyeglass number of degrees scope of lower vision area 2 be-50D extremely-600D.Certain eyeglass number of degrees described in the utility model are that the diopter according to eyesight arranges, and are not limited to above-mentioned eyeglass number of degrees scope.

Among the embodiment of the present utility model, upper vision area 1 and lower vision area 2 are that meridian 5 take eyeglass arranges as the axle center and according to the diopter of eyesight, forming as the upper vision area of looking the far field with as the lower vision area of near reading range, because those skilled in the art know, therefore detailed description no longer.
