Based on the fundamental task of the visual system, which is to receive information from the surroundings and to transmit it to the central nervous system, the visual system is described as being emmetropic if the amount of information received through the visual pathways is maximum when the eyes are unaided. A mathematical model of the dependence of the amount of information received through the visual channels on the eye's refractive power and range of clear vision has been worked out. The model, by showing good correlation with common experience, confirms the hypothesis that the amount of information is a coefficient of an eye's approximation to emmetropia and that the criterion of emmetropia of an eye is a particular case of the criterion of emmetropia of the visual system.
基于视觉系统的基本任务，即从周围环境接收信息并将其传输到中枢神经系统，如果在眼睛未矫正时通过视觉通路接收的信息量最大，则视觉系统被描述为正视眼。已经建立了一个数学模型，该模型描述了通过视觉通道接收的信息量与眼睛屈光力和清晰视觉范围之间的关系。该模型与常见经验显示出良好的相关性，证实了以下假设：信息量是眼睛接近正视眼程度的一个系数，并且眼睛正视的标准是视觉系统正视标准的一个特殊情况。
