Description
Technical field
The present invention relates to the improved method of the correction of refractive errors of a kind of human eye and system, more particularly relate to the distortion reducing and eliminating glasses imaging to improve the method and system of vision correcting.
Background technology
Consumer to adapt to the big problem that secondary new glasses are eyewear industry.This problem is relevant with the distortion of glasses imaging in general, and it is a painful experience that some people is come lecture by the adaptation of new glasses.Once the distortion of glasses is not handled well, three consequences can be caused.First, consumer generally requires one and adapts to fortnight, and everyone experience can vary with each individual.Second, because consumer does not adapt to new glasses, suitable new glasses can be abandoned, and owing to new glasses improve vision really, adapts to the responsibility that new glasses are individuals, abandons a pair of glasses and can cause loss economically.3rd, there is quite a few people can all can not get secondary suitable glasses in multiple optician's shops, they will cast off a glasses approach as vision correcting once and for all.
Fig. 1 shows the optometry process of eyewear industry today, and it relies on optometrist technology and experience determines the starting point of optometry and the final prescription of glasses.First, carry out the objective measurement of acquisitor's ametropia with computer refraction system 11, and obtain an approximate objective refraction list 12, including a concave-sphere number of degrees Fs, a mean of cylindrical diopter Fc, and a post mirror shaft angle degree Fa.Second, after optometrist can determine concave-sphere number of degrees substantially by refractor 13, the then subjective feedback according to computerized optometry list, the experience of optometrist and technology, tested people, " subjective optometry " carrys out subjective optimization concave-sphere number of degrees, mean of cylindrical diopter, and post mirror shaft angle degree.The first step of subjective optometry is optimization post mirror shaft angle degree, optometrist can according to his experience, the astigmatism degree of objective refraction, astigmatism angle arrange refractor, then measured people is allowed to obtain the feedback of measured people referring again to visual acuity chart referring initially to an astigmatism dish, adjustable column mirror shaft angle degree is carried out, until completing the subjective optimization of post mirror shaft angle degree according to feedback.The second step of subjective optometry is optimization mean of cylindrical diopter, optometrist can according to his experience, the astigmatism degree of objective refraction and be responsible for the astigmatism angle determined to arrange refractor, visual acuity chart obtains the feedback of measured people to allow measured people see, then according to feeding back the adjustable column mirror axle number of degrees gradually, until completing the subjective optimization of post mirror axle focal power.3rd step of subjective optometry is the optimization concave-sphere number of degrees, optometrist can according to his experience, the astigmatism angle that the subjective astigmatism degree determined, supervisor have determined is to arrange refractor, visual acuity chart obtains the feedback of measured people to allow measured people see, then the adjustable column ball axle number of degrees gradually, until completing the subjective optimization of post ball axle focal power.Optometrist can repeat same step to complete another subjective optometry of measured people.3rd, it is determined that the final prescription of glasses, including the subjective concave-sphere number of degrees fs optimized of each, the subjective mean of cylindrical diopter fc optimized, the subjective post mirror shaft angle degree fa optimized.Tradition optometry completes the purpose improving vision really, but whether tested people can like the new glasses of vision providing improvement to be diverse problem.
Fig. 2 shows the another kind of prescription new method determining numeral customization glasses based on wavefront measurement.First, an aberroscope is used for measuring all ametropia of human eye.Because aberroscope wave front detector not only accurately measures focusing error and the astigmatism (being made up of mean of cylindrical diopter and post mirror shaft angle degree) of human eye, and other senior aberration can be measured, such as other all irregular aberrations of coma, spherical aberration and human eye, can be more accurate than traditional computer refractometer.Second, produce a wavefront refraction list 22, including the concave-sphere number of degrees Fs that a wavefront optimizes, the mean of cylindrical diopter Fc that a wavefront optimizes, and the post mirror shaft angle degree Fa that a wavefront optimizes.High accuracy based on wave front detector and the wavefront optimization according to senior aberration, the mean of cylindrical diopter Fc of wavefront optimization and the post mirror shaft angle degree Fa of wavefront optimization are optimum, it is not necessary to subjective optimization.3rd, optimizing the concave-sphere number of degrees with refractor 23 is subjective, operator is according to mean of cylindrical diopter and the post mirror shaft angle degree of the objective optimization of wavefront and arranges refractor, the feedback of allow measured people see measured people that visual acuity chart goes, then the adjustable column concave-sphere number of degrees gradually, until completing the subjective optimization of post ball axle focal power.Optometrist can repeat same step to complete another concave-sphere number of degrees subjective optometry of measured people.3rd, it is determined that the final prescription of glasses, including the subjective concave-sphere number of degrees Fs optimized, the mean of cylindrical diopter Fc that wavefront optimizes, the post mirror shaft angle degree Fa that wavefront optimizes of each.
The wavefront methodologies of Fig. 2 the traditional optometry than Fig. 1 can actually obtain better vision correcting.But, the traditional optometry with Fig. 1 is the same, and whether tested people can like the glasses of new wavefront optimization to provide the vision improved can be diverse problem.

nullAs we know that in the selection optimizing visual quality and optimization visual distortion，Conventional optometry is only all to optimize visual quality for target (i.e. visual quality optimization)，But there is quite a few eyeglass wearer but can not adapt to for a long time after the correction of refractive errors glasses of the high visual quality that optometry obtains on wearing、Bring various discomfort，Even cannot adhere to wearing，Study for a long period of time through us and know that we may produce bigger visual imaging distortion while pursuing high visual quality in fact，And this visual distortion just of discomfort is brought to wearer，Research show when we regulate rectification parameter suitably reduce visual quality time，Visual distortion can be obtained by very big improvement，Namely when visual quality is more excellent (rather than optimum during optimization visual quality)，Visual distortion obtains very big optimization, and (visual distortion is greatly reduced，Thus reaching wearer to be fully able to the degree of acceptance)，The mode selecting to be exactly to optimize visual distortion of this optometry parameter.
This optimization visual quality and optimizing after the selection of optometry parameter (the one the second objective refraction lists or the one the second initial prescription) of visual distortion can pass through the objective refraction a series of refraction data of measurement device objective measurement obtains according to calculating；Refraction data can also be inputted by entering apparatus, then pass through calculating and obtain；Can also obtain either directly through entering apparatus input.Final after have passed through subjective parameters optimization, it is thus achieved that the prescription of at least two glasses, one is optimize visual quality, and one is optimize visual distortion, and the measured is by choosing the secondary glasses being suitable for oneself actual wear after trying on.It not optimum still enough good although the people that visual distortion is more sensitive just can be obtained a secondary visual quality by a part and be suitable for the glasses oneself worn.
The objective refraction list of this selective different parameters, initial prescription or final prescription, it is possible to be two that include visual quality optimization and visual distortion optimization；Can also be several of change of going forward one by one, in order to the measured can select the prescription that is really suited for oneself and corresponding glasses by change of going forward one by one in various degree, a pair really can be found at enough clear and enough perfectly balanced glasses between adaptation.And such visual quality of rationally slightly abandoning dexterously is to obtain the scheme that visual distortion optimizes, prior art was never attempted, technical scheme provides a brand-new thinking, brings revolutionary change to vision correcting person undoubtedly, it is likely to allow the crowd worn glasses have never again need to adapt to worries for a long time to newly getting the right lensses for one's eyeglasses so that people obtain extremely good impression at the very start and experience wearing newly to get the right lensses for one's eyeglasses.
