According to a method for determining metamorphopsia based on user interaction disclosed as an embodiment of the present invention, a test chart may be displayed to a user, an input from the user for a part which is perceived as being distorted in the displayed test chart may be received, and a metamorphopsia degree of the user may be accurately determined based on a distortion area selected according to the received input. Further, according to another embodiment of the present invention, a test chart may be displayed to a user, a response (e.g., distance values of points, an area value, etc. in a zone) for each zone for the test chart may be received from the user, and metamorphopsia of the user may be determined based on the received response.

The invention relates to a method for examining an eye of a patient by the patient themselves by means of an ophthalmological apparatus, said apparatus having front optics and an apparatus pupil. According to said method, the patient positions the ophthalmological apparatus relative to the eye, a measure of the deviation of the pupil of the eye from the apparatus pupil is determined, and a pupil correction signal is produced depending on the measure of the deviation, said pupil correction signal specifying a direction and/or a degree of the deviation and being output to the patient. The patient can use the pupil correction signal for repositioning in relation to the ophthalmological apparatus with a smaller deviation.
