The present invention relates to a standard model eye lens for an optometric visual refractometer and, more specifically, to a standard model eye lens to be used when correcting the optometric visual refractometer, which is a device having a continuous or digital reading device to be used when measuring the refraction of the eyes. To this end, the present invention can provide: a standard model eye lens of which the rear surface part is rough-polished and a reticle is attached or coated on the rough-polished surface thereof; or a standard model eye lens of which the rear surface part is optically polished and a reticle is attached or coated on the optically polished surface thereof. Therefore, the present invention provides an effect of enabling the precise measurement of the focal distance of a standard model eye lens.
