Calculation module, system and computer-implemented method for determining at least one cause of a visual fatigue of a patient

A system for determining at least one cause of a visual fatigue of a patient, the system comprising a calculation module for determining at least one cause of a visual fatigue of a patient and a display, wherein the calculation module is configured to

• obtain values associated respectively with physiological parameters of the patient,
• obtain causality coefficients associated respectively with the physiological parameters,
• normalize the values to obtain normalized values associated respectively with the physiological parameters,
• determine normalized scores associated respectively with the physiological parameters, based on the causality coefficients and the normalized values,
• select at least one of the physiological parameters, using the normalized scores, as the at least one cause of the visual fatigue, and
• command the display unit to display the at least one selected physiological parameter.

A computer-implemented method for determining at least one cause of a visual fatigue of a patient, the computer-implemented method comprising:

• obtaining values associated respectively with physiological parameters of the patient,
• obtaining causality coefficients associated respectively with the physiological parameters,
• normalizing the values to obtain normalized values associated respectively to the values,
• determining normalized scores associated respectively with the physiological parameters, based on the causality coefficients and the normalized values, and
• selecting at least one of the physiological parameters, using the normalized scores, as the at last one cause of the visual fatigue.
