<p>In order to measure the behaviour of the head and eyes of a wearer looking at a target, said wearer being provided with a contact lens having several areas, the wearer target vision varies from one lens area to the other, said areas can have different colours. Afterwards, the area through which the wearer sees the target is determined for a lateral target with respect to a main direction of view, thereby making it possible to calculate the movement of the wearer eyes with respect to his trunk. Said invention makes it possible to measure the behaviour of the bearer's head and eyes when he looks at the target.</p> |
