ABSTRACT:
Process of assessment of ocular dysfunctions, characterized in that the patient's eye (1) is placed to a previously defined distance from a lightening glare source (3), so that he can visualize a target (4) placed next to the lightening glare source (3), then the target (4) is approached from the source (3) so that the patient becomes unable to distinguish the target (4) from the source (3) and then, the target (4) is slowly taken away from the source (3), up to the exact moment when the patient distinguishes again the target (4), and at this time, the incident light angle o between the source (3) and the target (4) is measured.
