Embodiment Construction

[0037] figure 1 A vision testing system 10 is shown with a display device 11 comprising a backlit screen 12 in the manner of a television or tablet computer. The display device 11 is provided with a camera device 13 with a camera 14 via which at least one value characterizing an optical parameter of a trial lens not shown here is recorded. Furthermore, the vision testing system 10 includes a control device (also not shown here), by which the display device 11 is controlled, and the numerical value is recognized by the control device through image processing. Via the screen 12, visual acuity test symbols are visualized for the subject to establish subjective refraction values ​​for the subject's eyes. During the eye test, a trial frame (not shown here) of the vision testing system 10 is positioned in front of the subject's eye, the trial frame having a trial lens.

[0038] figure 2 A trial lens 15 is shown, comprising a lens 16 and a frame 17 with a handle 18 . Furthermore...

Abstract

The invention relates to a method for testing an eye of a subject by means of a vision testing system (10) and to a vision testing system. A trial frame of the vision testing system is arranged in front of the eyes, the trial frame is provided with at least one trial lens, at least one numerical value representing an optical parameter of the trial lens is recorded through a camera (14) of a cameradevice (13) of a display device (11), and the display device is controlled by a control device of the vision testing system. The numerical values are identified by the control device through image processing, and the numerical values are used for identifying the sphere and/or the cylinder and/or the axis and/or the prism.

Description

technical field [0001] The invention relates to a method for testing the eyes of a subject by means of a vision testing system, as well as to a vision testing system, the vision testing system having a trial frame arranged in front of the eye, said trial frame having at least one trial lens. Background technique [0002] Such vision testing systems are sufficiently known from the prior art and are generally used for performing eye tests. For example, known vision testing systems are provided with a display device having a screen through which vision testing symbols can be visualized or presented to the subject. Such a vision test system may also include a control device via which an operator can control the presentation of vision test symbols on the screen. Depending on the type of screen, the screen can also be provided with linear or circular polarization. The polarization of the screen is usually used to perform the eye test with a trial frame or phoropter placed in fro...
