摘要： A method, a computer program, and a device for determining at least one astigmatic effect of at least one eye of a person are disclosed, as well as a related method for producing at least one spectacle lens for the at least one eye of the person. The method for determining the astigmatic effect includes:
a) displaying an image to an eye of the person, the image including a line with a plurality of sections, wherein an orientation of each section with respect to an optical axis of the image differs from each other, respectively;
b) recording a reaction of the person to the image at at least one point in time; and
c) determining at least one value for at least one astigmatic effect of at least one eye of the person by evaluating the at least one reaction of the person at the point in time.-

摘要： A method, a computer program product, and a system for determining an optical parameter of an optical lens, as well as a related method for producing the optical lens by adjusting the optical parameter are disclosed. The method includes:
a) capturing an image picturing the optical lens by using a camera; and
b) determining an optical parameter of the optical lens by processing the image,
wherein the camera generates a signal related to a position of a focus, and the optical parameter of the optical lens is determined by using the signal related to the position of focus.
The method and the system allow determining the optical parameter of the optical lens in a direct fashion by applying the signal related to the position of the focus as generated by the camera as a measured value for the optical parameter of the optical lens.-

摘要： Methods and devices for measuring the vision of a person are provided The method includes determining a distance between a measurement device and the person. The distance is determined by communicating between a first wireless communication interface of the measurement device and a second wireless communication interface of a portable device on the person. Then, the vision measurement is performed based on the distance.
