The disclosure relates to a method and a respective computer program with a program code to execute the method. In particular, disclosed is a method for training a preferred retinal locus of fixation (efficient PRL) for a person having an eye with a field of vision comprising an area of partially diminished or entirely degenerated visual acuity. The method includes: a) determining an inefficient retinal region outside the area in the field of vision of the eye of the person and a more efficient retinal region for the specific vision task outside the area in the field of vision of the eye of the person and b) inducing a preferred retinal locus of fixation (efficient PRL) for a vision task outside the inefficient retinal region but in the more efficient retinal region. In addition, the disclosure relates to a device for performing the method.
