Abstract
A kind of personalized optical mirror slip and its design method for nighttime driving, the optical mirror slip not only has the optical property of ordinary resin eyeglass, the distant vision in the daytime that its central optical zone can effectively correct glasses wearer is ametropia, and the refractive power of periphery transition region radially direction decline trend after optical design, lead to that the neighboring area of the optical mirror slip is higher than central area near vision refractive power or hyperopic refractive degree is lower, the night myopia of glasses wearer can be effectively relieved, fill up the blank in the market without the driving optical mirror slip for alleviating night myopia.Optical mirror slip of the present invention need to carry out optical design on the basis of comprising the vision prescription of photopic vision and noctovision, individualized feature is obvious, it is particularly suitable for wearing when nighttime driving and uses, mainly for the night myopia degree intensification problem increased because of night pupil aberration bigger than normal and complete etc. caused by factors.
Description
Technical field
Present invention relates particularly to optics design technical fields, and in particular to a kind of personalized light for nighttime driving
Learn eyeglass and its design method.
Background technique
For normal eye in day time, pupil is relatively small, and ambient mainly passes through and assembles in lenticular paraxial region
In on macula retinae, thus human eye can clearly regard object.But at night, pupil of human increases more in the daytime, by crystalline lens
The light of neighboring area increased significantly, and human eye dioptric system cannot maintain ideal image state again, and ambient is caused to converge at
Before retina, to slight myopic occur, this phenomenon is known as night myopia phenomenon.It is the special physiological structure institute by human eye
It causes, including eye cornea and lenticular configuration of surface are in aspherical, crystalline lens refractive index from center to periphery change of gradient etc.
Factor.It can be seen that glasses wearer in the daytime needed for correct refractive power and generally existing difference needed for night, particularly with driving
Person keeps the demand of day and night same clear view object more urgent.
Optical resin lens clinically are for different crowd, different purposes, design method multiplicity at present.It is existing to be directed to
The spectacle lens and its design scheme of driving consider the factor of light penetration more, and there is no draw attention to night myopia.And
Although concentric-ring pattern periphery defocus near-sighted glasses periphery defocus area is different from central optical zone refractive power, due to for crowd and
Action principle is different, leads to design meeting in periphery defocus area so that glasses wearer's night myopia becomes apparent, is not particularly suited for delay
Solve the crowd that night myopia is target.
Summary of the invention
It, can be with equally holding view object is clear in the daytime in nighttime driving in order to alleviate the night myopia phenomenon of glasses wearer
Clear, the present invention provides a kind of personalized optical mirror slip and its design method for nighttime driving, provided resin lens
Not only have optical property possessed by ordinary resin eyeglass, and the night myopia of glasses wearer can be effectively relieved, is driven conducive to night
It sails.
The technical solution that the present invention uses is: a kind of personalized optical mirror slip for nighttime driving, the light
Eyeglass is learned using optical centre as dot, three working regions are divided into according to radial radius: central optical zone, periphery transition region,
Other peripheral region, the refractive power of the central optical zone keeps stablizing, and meets the diopter correction amount under photopic conditions, institute
The other peripheral region refractive power stated keeps stablizing, and meets the diopter correction amount under the conditions of noctovision, the periphery transition region
On refractive power numerical value radially taper off since the outer boundary of central optical zone trend, until reaching outside the transition region of periphery
The refractive power numerical value of boundary.
Diopter correction amount on the periphery transition region is rectified from the diopter under the photopic conditions of central optical zone
Positive quantity starts radially in gradual change trend, until the diopter under the conditions of reaching noctovision at the outer boundary of periphery transition region is rectified
Positive quantity.
The refractive power numerical value of the periphery transition region with radius increase be in concentric-ring pattern decline trend, change rate it is absolute
Value≤0.03D/mm.
The optical mirror slip is resin lens, glass lens or film eyeglass.
The central optical zone radius R1 >=2.5mm.
The periphery transition region outer boundary radius R2 >=30mm.
The optical mirror slip is refractive power radial gradual face on one side, and another side is ring curved surface, spherical surface or aspherical.
The diopter correction amount is myopic refractive degree correct amount or hyperopic refractive degree correct amount.
A kind of design method of the personalized optical mirror slip for nighttime driving, comprising the following steps:
(1) it obtains lens wearer and matches mirror clinic prescription, prescription must the subjective refraction result comprising photopic vision and dark
The subjective refraction result of vision；
It (2) is three working regions: central optical zone, week according to radial radial design by eyeglass using optical centre as dot
Side transition region, other peripheral region；
(3) refractive power of the central optical zone of eyeglass is met into the requirement of the vision prescription under photopic conditions, other peripheral region is bent
Luminous power meets the vision prescription requirement under the conditions of noctovision, and keeps stablizing；
(4) refractive power numerical value on the transition region of periphery is made radially to taper off since the outer boundary of central optical zone trend,
Until reaching the refractive power numerical value at the outer boundary of periphery transition region, and absolute value≤0.03D/mm of change rate, use is finally obtained
In the design scheme of the personalized optical mirror slip of nighttime driving.
The beneficial effects of the present invention are: the present invention provides a kind of personalized optical mirror slip for nighttime driving and its setting
Meter method, the resin lens not only have the optical property of ordinary resin eyeglass, and central optical zone can effectively correct glasses wearer
Distant vision in the daytime it is ametropia, and the refractive power of periphery transition region radially direction decline trend after optical design,
Lead to that the neighboring area of the optical mirror slip is higher than central area near vision refractive power or hyperopic refractive degree is lower, can be effectively relieved and wear
The night myopia of mirror person fills up the blank in the market without the driving optical mirror slip for alleviating night myopia.Light of the present invention
Optical design need to be carried out on the basis of comprising the vision prescription of photopic vision and noctovision by learning eyeglass, and individualized feature is obvious, especially
It is suitble to wear when nighttime driving and uses, mainly for because of the night caused by the factors such as night pupil aberration bigger than normal and full increase
Myopia degree deepens problem.
