METHOD, DEVICE, AND COMPUTER PROGRAM PRODUCT FOR DETERMINING A SENSITIVITY OF AT LEAST ONE EYE OF A TEST SUBJECT
In a method for determining a sensitivity of at least one eye (12) of a test subject (10), determination of a subjective refraction result is carried out for the at least one eye (12) of the test subject (10). While carrying out the determination of the subjective refraction result, a first visual acuity of the at least one eye (12) is determined for a first applied refraction. While carrying out the determination of the subjective refraction result, a second visual acuity of the at least one eye (12) is determined for a second applied refraction, wherein the second applied refraction is different from the first applied refraction. The sensitivity of the at least one eye (12) is ascertained taking into consideration the first and the second visual acuity for the first and the second applied refraction.

In a method for determining optometric parameters of a subject (10), an optical correction for at least one eye (12) of the subject (12) is set by means of a refraction unit (14; 36). A test image for determining the subjective refraction of the subject (10) is displayed. A viewing direction (R) and/or an orientation of the at least one eye (12) of the subject (10) is detected by means of an eye tracking unit (16) while the subject (10) is looking at the displayed test image. An eye signal is created which contains information relating to the detected viewing direction (R) and/or orientation of the at least one eye (12) of the subject (10). The optometric parameters of the subject (10) are determined by evaluation of the eye signal in accordance with the displayed test image.

An optical element includes a substrate and an interferometric reflection-reducing layer system on at least one surface of the substrate. The layer system includes a stack of at least four successive layer packets, wherein each layer packet includes a first sub-layer with a first optical depth and a second sub-layer with a second optical depth which differs from the first optical depth. The refractive index of each first sub-layer nearer the substrate is greater than the refractive index of each second sub-layer further away from the substrate, of the respective stack, wherein the layer system has a brightness, a colorfulness, and a hue angle of a residual reflection color. The value of a change in the hue angle of the residual reflection color in a range of a viewing angle with the boundary values of 0° and 30° relative to a surface normal to the layer system is smaller than the value of a change in the colorfulness in the range of the viewing angle.
