Method for optimizing the conditions of implementation of vision contrast test, and corresponding system

A method for optimizing the conditions of execution of a contrast test vision quecomprende the following steps: a) if it is performing a visual acuity test, a procedure of "Calibration deIluminacion Environment", comprising running stages: a1) a level of ambient lighting is measured; a2) if the illumination value is within a threshold S1, then the seindica event as positive; a3) if the conditions are within a threshold S2, then the event indica as intermediate; a4) if conditions are not within the threshold S2, then the event indica as negative; b) if the procedure "Calibration Lighting Environment" is not successful and no examencertificado requested, then executing a procedure "Adjust Emission Display" comprising lasetapas; b1) if the ambient lighting conditions are higher than the norm, then s and increases brillodel display device; b2) otherwise, if the ambient lighting conditions are lower than the norm, then sedisminuye the brightness of the display device; b3) if it is not possible to vary the brightness in order to obtain a session of effective testing, acontecimientose indicated accordingly; b4) if the adjustment has been successful, the event indicated accordingly; c) otherwise, if a certificate examination or, if not possible to complete the procedure is requested "Emission Display Set", the program exits the main procedure, giving a resultadonegativo; d) otherwise, if it is not performing a visual acuity test, one procedimientode "autocalibration", comprising the steps is executed: d1) a reflective dome is placed in position; d2) a color detection sensor is placed in position; d3) a sequence of images is projected; simultaneously, the brightness is detected and coloresque emitting display device; d4) if necessary, the emission curve is corrected, and the process returns to step d2, d5) if no correction is necessary, the process ends.
