A computer-implemented method for determining a visual performance of at least one eye of a person, the method comprising the following steps: a) displaying to at least one eye of a person at least one visual stimulus configured to elicit at least one type of eye movements in the at least one eye of the person by using at least one screen; b) tracking the at least one type of eye movements in the at least one eye of the person by using at least one eye tracker; c) determining the visual performance of the at least one eye of the person by using at least one first piece of information about the at least one visual stimulus and at least one second piece of information about an occurrence of the at least one type of eye movements in the at least one eye of the person by using at least one processing unit, wherein at least a part of the at least one visual stimulus is displayed in a time-varying manner, whereby the at least one visual stimulus is presented in a manner that the at least one part of at the least one visual stimulus varies an appearance of the at least one visual stimulus to the at least one eye of the person over time, independent of whether the at least one type of eye movements is elicited in the at least one eye of the person or not, wherein the time-varying manner comprises continuously modifying the at least one part of the at least one visual stimulus by increasing or decreasing at least one value for the at least one parameter for the at least one part of the at least one visual stimulus between a lower value and an upper value in a monotonous manner, or between the upper value and the lower value in a monotonous manner, characterized in that the upper value is selected to elicit the at least one type of eye movements in the at least one eye of the person, and wherein the lower value is selected not to elicit the at least one type of eye movements in the at least one eye of the person. a) displaying to at least one eye of a person at least one visual stimulus configured to elicit at least one type of eye movements in the at least one eye of the person by using at least one screen; b) tracking the at least one type of eye movements in the at least one eye of the person by using at least one eye tracker; c) determining the visual performance of the at least one eye of the person by using at least one first piece of information about the at least one visual stimulus and at least one second piece of information about an occurrence of the at least one type of eye movements in the at least one eye of the person by using at least one processing unit, wherein at least a part of the at least one visual stimulus is displayed in a time-varying manner, whereby the at least one visual stimulus is presented in a manner that the at least one part of at the least one visual stimulus varies an appearance of the at least one visual stimulus to the at least one eye of the person over time, independent of whether the at least one type of eye movements is elicited in the at least one eye of the person or not, wherein the time-varying manner comprises continuously modifying the at least one part of the at least one visual stimulus by increasing or decreasing at least one value for the at least one parameter for the at least one part of the at least one visual stimulus between a lower value and an upper value in a monotonous manner, or between the upper value and the lower value in a monotonous manner, characterized in that the upper value is selected to elicit the at least one type of eye movements in the at least one eye of the person, and wherein the lower value is selected not to elicit the at least one type of eye movements in the at least one eye of the person.
