Eyeglass lens evaluation method, eyeglass lens design method, eyeglass lens manufacturing method, eyeglass lens manufacturing system, and eyeglass lens

Abstract

The invention relates to an eyeglass lens evaluation method, an eyeglass lens design method, an eyeglass lens manufacturing method, an eyeglass lens manufacturing system and an eyeglass lens. With respect to the evaluation of a custom-made eyeglass lens using a binocular vision function, the binocular vision function includes as a factor a measurement value which requires at least one of or both of the positive relative convergence and the negative relative convergence, of the positive relative convergence, the negative relative convergence, the positive relative accommodation, the negative relative accommodation, and the vertical fusional vergence.

Description

technical field [0001] The present invention relates to a spectacle lens evaluation method for performance evaluation when designing or manufacturing spectacle lenses, a spectacle lens design method using the spectacle lens evaluation method, a spectacle lens manufacturing method, a spectacle lens manufacturing system, and spectacle lenses. Background technique [0002] When evaluating and designing spectacle lenses, various evaluation methods and design methods have been proposed in order to obtain an optimum field of vision, and in particular, technologies focusing on visual acuity while wearing spectacle lenses have been proposed. For example, Patent Document 1 (WO2002 / 088828 A) discloses a technique for designing spectacle lenses using a visual acuity function. Patent Document 2 (WO2004 / 018988 A) describes spectacle lenses designed in consideration of the chromatic aberration of the visual acuity function. Here, the visual acuity function is a function representing visu...

Problems solved by technology

However, in Patent Document 3, what kind of astigmatism and adjustment error balance is good for binocular vision, and the degree of goodness is not quantitatively indicated.

Regarding this point, it is not clear how the spectacle lens described in Patent Document 3 is constituted.

[0008] Third, according to lines 25-44 of page 5 of patent document 3, the figure 2 The description of the optical system is not binocular observation function

Therefore, it is not suitable for the optical system with binocular observation function

[0010] Fourth, the patent document 3 Figure 4 The degree of distortion shown is incomprehensible

However, the amount of error in this case is very large when considering that the usual insertion amount for myopia in progressive power lenses is 2.5 mm.

[0014] The second problem is that the phenomenon of "the shift of the dominant visual direction to the dominant eye side" is in conflict with the only law of eye movement involving binocular observation, that is, Hering's law of equal innervations.

[0021] Second, regarding the definition of off-axis prism difference described on page 13 of Patent Document 5, it is only stated that "when the aberrations of the side head and the nose are not equal, defects in binocular vision will occur."

As a result, e.g. possible discomfort or increased fatigue
