Description
Technical field
The utility model belongs to the two-sided focus-variable lens of optical lens technical field more particularly to a kind of designed in mirror image.
Background technique
Chinese patent 201710727180.7 is " for the equidistant zoom point lens straight grain list in vision correction two lens group
Piece " devise multiple focus areas are presented on one piece of lens, each being changing into for focus area focus value is arranged successively gradually
Zoom point lens.This kind of lens design will appear diopter chattering in ripple and ripple transition section, lead to diopter not
Consecutive variations, to influence the effect of visual exercise.Also, the very poor N of lens strength numerical value of adjacent bar curved surface is 10 degree
Some value between to 100 degree, specific very poor value do not elaborate.Human eye tolerance diopter it is very poor more than 50 degree when,
Situations such as being then likely to occur vision dizziness.This kind of lens design can not really realize continuous dynamic zoom.So the technical solution
The effect of cannot achieve visual exercise.
Chinese patent 201520246792.0 " one kind can any focus-variable lens group " provides one kind: one of every eyeglass
Surface is horizontal plane, another surface of eyeglass is the non-aqueous plane surface for meeting mathematics changing rule height and rising and falling；The mirror
A highest point and a minimum point are provided on the non-aqueous plane surface of piece；The highest point of the non-aqueous plane surface of the eyeglass with most
Multiple optical centres of consecutive variations are evenly distributed between low spot, along the non-aqueous plane surface of eyeglass；Multiple optical centres
Refractive diopter successively successively decrease or be incremented by.The zooming range of this kind of focus-variable lens group is+3.00D~-8.00D.For middle height
The negative lens training section of myopia population is limited, is unable to reach the effect of whole visual function training.
With the development and the progress of science and technology of society, influenced by electronic product and the exacerbation of school work task, great Liang Qing
Children form the ametropia problem such as myopia, long sight, astigmatism, amblyopia, thus largely come into being depending on health product.
Meanwhile with the variation of countries population's age composition, the ratio in person in middle and old age group is gradually expanding, and presbyopic phenomenon will be in vast
Elderly population brings great vision inconvenient.On the market most of visual rehabilitation mechanism or teenager is needed depending on health product
Children go to professional institution to carry out long-term visual exercise service, expend a large amount of adolescents with learning and life-time, give teenager
Children's daily life brings great inconvenience.
Presbyopic glasses and common progressive multifocal lenses are solving the problems, such as that presbyopic similarly faces more limitation, for example carry
The features such as inconvenience, zoom amount is small.This kind of varifocal amount of eyeglass is small, Zoom optical region (i.e. zoom visible area) is very narrow, periphery
The distortion of aberration region is larger, and it is inadequate to wear usage comfort.
Utility model content

Count to the transitional region of the maximum negative degree of N point, i.e. transitional region of the highest point to line between minimum point.The area A is marginal aberration
Region, i.e. region between eyeglass highest point, minimum point and highs and lows except transitional region.
The thickness of the free form surface highest point, the thickness of free form surface minimum point, free form surface the highest point and the lowest point
The ratio range apart from three between 10:0.5:50~20:1.8:120.
Free form surface highest point power range is+5.00D~+10.00D, the free form surface minimum point dioptric
Degree range is -10.00D~-20.00D.
The two-sided focus-variable lens power range of the zoom curved surface composition of described two symmetrical designed in mirror image is+20.00D
~-40.00D linear zooming.
The utility model has the advantages that the utility model carries out two-sided mirror image free form surface by overturning conventional lenses fabrication design thinking
Zoom design, realizes large-scale continuous vari-focus, and the technologies such as image-jumping phenomenon, zooming range deficiency in the prior art that break through lack
It falls into.It can regular be various non-pathologic, non-organic by the free zoom of crisscross motion bring of free surface lens
Ametropia crowd and the amblyopia crowd of certain dioptric properties carry out scientific and effective visual exercise.To reach improvement, it regards function
It can, promote visual capacity, alleviate the problems such as asthenopia.
