An optical system (100) for following ocular movements of an individual includes: an acquisition module (190) designed so as to acquire an image (Im) of the two eyes (22, 22d, 22g) of the individual, an optical element of transmission (110d, 110g), to the acquisition module, of two images (lm_d, lm_g) of respectively each eye which together correspond to a discontinuous region (24d, 24g) of the face, by multiple reflections along two optical routes (TOd, TOg) devoid of any semireflecting mirror. The optical routes further include optical input paths (114d, 114g) opposite respectively each eye, which are parallel to one another and to an optical axis (Z) of the acquisition module, and the optical element of transmission is configured so as to bring the two images closer together so that the acquisition module acquires the two images simultaneously.
