Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
The utility model provides a kind of spectacle lens, as depicted in figs. 1 and 2, including the first dioptric region 1 and the second dioptric area
Domain 2, the first refractive power that first dioptric region 1 has the hyperopic refractive based on correction ocular not positive, i.e., described first bends
Light region 1, which has, focuses on the function on the retina of eyes for image, and second dioptric region 2 has by described the
One refractive power increases the refractive power born and the negative refractive power obtained, and is suitable for focusing on image on the position at retina rear.
As shown in Figure 3 and Figure 4, spectacle lens described in the utility model are that have to inhibit hypermetropia-development while correcting long sight
The eyeglass of effect, the spectacle lens are the convex lenses with object side surface 5 and eye side surface 6, wherein the formation of object side surface 5
For towards the convex surface of object side, eye side surface 6 is formed towards the convex surface of a side, which has the first dioptric region
1 and the second dioptric region 2, first dioptric region 1 has ametropic first refractive power based on correction ocular, described
Second dioptric region 2 includes multiple independent island regions, and second dioptric region 2 covers following region: with the glasses
The optical centre of piece is the radius R in the center of circle1For the circle O of 20mm.
Fig. 3 is a kind of sectional view of embodiment of the utility model spectacle lens, and Fig. 4 is that enlarged structure is illustrated at C in Fig. 3
Figure, wherein the shape of each independent island 4 is relative to first dioptric region 1 in second dioptric region 2
Surface is towards the concave shape of object side, and the concave surface of the object side is with the curvature of the eye side surface 6 than the first dioptric region 1
Big curvature, therefore, second dioptric region 2 have a negative refractive power, the refractive power in second dioptric region 2 be pass through to
First refractive power increases the refractive power born and the negative refractive power obtained.In said structure, it is watched forward by the spectacle lens
When object, sight passes through spectacle lens to watch object, in the same of the visual picture for distinguishing the object by the formation of the first dioptric region 1
When, by the picture that is formed due to the second dioptric region 2 at retina rear the development that inhibits long sight.
But human eye can generate dizziness, visual fatigue etc. when penetrating the second dioptric region 2 in above-mentioned border circular areas
Malaise symptoms make second dioptric region 2 remove following region in the round O in order to which this sense of discomfort is effectively relieved: with
A radius 3 in the round O vertically downward rotates the fan-shaped region of 0~30 ° of formation to nasal side；And the radius 3
To the rectangular area formed far from nasal side direction translation 2mm.Because human eye is when regarding close, eyeball downwards, can be moved inwardly,
And the above-mentioned region removed from the second dioptric region 2 region for most often passing through when being sight near work, this part is from the
The region removed in two dioptric regions 2 is the first dioptric region 1, and sight extraordinary can be distinguished by the first dioptric region 1
Object out, wearer are arranged almost without sense of discomfort by above structure, and eyeglass can be effectively relieved during wearing
The sense of discomfort of generation improves the comfort that human eye is worn.
When the mobile sight of eyes deviates central part and passes through peripheral portion, peripheral portion i.e. the first dioptric region 1, in retina
The upper picture for forming object, extraordinary can identify object, even if eyes are mobile, wearer is also almost without sense of discomfort.Cause
This, which is able to suppress the function of the ametropic development of eyes while correcting long sight, and can ensure that human eye is worn
The comfort worn.
Wherein, the area of each independent island 4 is 0.0314mm2, and each independent island 4 is radius
R is the circle of 0.1mm, and the center spacing L of each adjacent independent island 4 is 0.3mm, can obtain better visual effect
And wearing comfort.
As shown in Figure 5 and Figure 6, in the utility model another embodiment spectacle lens, second dioptric region 2 is not covered
Lid following region: using the optical centre of the spectacle lens as the radius R in the center of circle2For the border circular areas of 2.5mm~10mm.Other knots
Structure have with structure identical in above embodiment, be no longer described in detail herein, can also obtain this using the embodiment
The effect of utility model.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail in conjunction with attached drawing above
Detail in above embodiment can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of simple variants, these simple variants belong to the protection scope of the utility model.
It is further to note that specific technical features described in the above specific embodiments, in not lance
It in the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the utility model is to each
No further explanation will be given for the possible combination of kind.
In addition, any combination can also be carried out between a variety of different embodiments of the utility model, as long as it is not disobeyed
The thought for carrying on the back the utility model, equally should be considered as content disclosed in the utility model.
