The paper presents the development of a an innovative solution to increase the efficiency of the protocol for a correct and complete visual function testing protocol efficiency increasing among drivers. A non-conventional method has been accomplished, thus meaning two main steps: the first one invoked the programing and testing of a hardware interface for a complete and proper assisted testing, using a laptop or tablet device. The interface envisaged all necessary aspects in terms of visual testing: near and far acuity, response reaction, hand-eye coordination, vision in night conditions. The second step meant a device manufacturing in terms of optic, mechanic and hardware components for night conditions inducing in drivers. For this purpose a special lamp was realized, including several LEDs, commended by a hardware system, simulating different night condition while driving. An example could refer to simulate the appearance of a car coming from the opposite direction, having the meeting phase or the driving phase activated. The hardware system consisted in a developing board, the main component being an Arduino Uno programmed microcontroller. Finally the proposed method was tested due to several persons, having B and C driving license, and proved to be very efficient and useful one for the staff engaged for periodic medical control in drivers.
