Abstract: Disclosed is a measurement method for determining a value of a visual correction need for near vision of an individual in a natural posture for near vision. A recognizing limit distance is determined so that the individual is able to recognize at least one predetermined symbol farther than the limit distance relatively to the individual and unable to recognize the at least one predetermined symbol closer to the individual than the limit distance. A portable medium displaying the predetermined symbol is displaced in front of the face and eyes of the individual to change a frontal distance between his/her eyes and the portable medium and in which when a recognizing limit distance is detected by the individual, the limit distance is measured and the value of the visual correction need is determined from the measured limit distance, wherein the visual correction need includes an accommodation compensation need.
