MUMBAI, India, June 19 -- Intellectual Property India has published a patent application (202617058805 A) filed by Carl Zeiss Vision International Gmbh on May 08, 2026, for Methods And Devices For Determining At Least One Refractive Value.
Inventors include Leube, Alexander; Huebner, Julia; and Breher, Katharina.
The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The present invention relates to a method (210), a computer program and a determining device (110) for determining at least one refractive value (212) of an eye (112) of a person, a data carrier signal, a field device for generating input data (214) for determining at least one refractive value (212) of an eye (112) of a person, a remote device for generating outcome data (222) for determining at least one refractive value (212) of an eye (112) of a person, a method for generating a geometrical model (226) of at least one spectacle lens (228) for producing the at least one spectacle lens (228), and a method for producing at least one spectacle lens (228). Herein, the method (210) comprises the following steps: a) generating input data (214) configured to comprise - an uncorrected distance visual acuity Vsc (216) of the eye (112) of the person; - a meridian direction (220) of an astigmatism of the eye (112) of the person; - a distance (140) between the eye (112) of the person and at least one visual stimulus (118) displayed to the eye (112) of the person, wherein the at least one visual stimulus (118) is simultaneously aligned in the meridian direction (220) of the astigmatism and a direction perpendicular thereto; b) generating outcome data (222) configured to comprise - at least one refractive value (212) of the eye (112) of the person, wherein the at least one refractive value (212) of the eye (112) of the person is determined by evaluating the input data (214), wherein the distance (140) between the eye (112) of the person and the at least one visual stimulus (118) is determined from response of the person indicating that the at least one visual stimulus (118) has been perceived by the person to have an equivalent blur in the meridian direction (220) of the astigmatism and in the direction perpendicular thereto. The present invention provides a fast, easy, versatile, reliable and accurate approach for determining at least one refractive value (212) of an eye (112) of a person.
