We discuss about the characteristics a system to measure the Contrast Sensitivity Function in the ophthalmologic clinic has to have. We propose this system should be computer based on to assure flexibility and precision. Besides the original calibration, this equipment needs incorporate an auxiliary system to keep the working conditions doing periodical gamma corrections. We try a calibration method based on visual comparisons and show it is valid and simple. We propose the use of an adaptive psychophysics method to obtain the contrast thresholds that assure a good compromise between precision and duration of the whole test. Finally we propose the system has to have their own normality curves for the different age ranges allowing the practitioner performs clinical evaluations. In summary, we can say that taking into account the mentioned topics, the fidelity of the stimuli will be guaranteed and the challenges entailed in its transference to the clinic will be overcome.
