In the chapter Blue Breezes, gradient in fine arts is related to the capacity of the subject to assimilate and perceive images with decreasing clearness from the point of acutest vision to the blind periphery of the visual field. My account on space-time-colour corroborates the well-known opinion that visual tests exert greater psychical influences when they are included in art compositions than when they are used independently. Bioptical compositions of this kind may play the part of educational factors in general. They are also particularly valuable for training reflexes related to visual stimuli (at an angle of almost 180o on the horizontal). Their use may be recommended to sportsmen, the military, drivers, etc.
Reproduction R11 shows my sketches published in the "Arta" magazine, no 9-10 (1990). My experiments have pointed out that training wide-angle vision is extremely efficient in the case of a specific composition, viz.: a central area with bioptical elements, flanked on either side by an art hiatus (a monochromatic area devoid of figures), and towards the margins, on either side, evincing figures in vivid colours. This principle may be extended by applying the procedures presented in my patent RO 112061, with the help of groups of computers. For instance, two screens in the centre of the field of vision and two screens on either margin of the field.
Training programmes may thus be established, involving moving figures, which modify their apparent positions in depth in the course of time and also successively change their colour.
It is proved that with normal binocular vision subjects, when vision is focused on the centre of the field, there occur cyclic shiftings of attention, focusing now to the centre, now to the margins, at time intervals of some 5 to 10 seconds.
Training reflexes aims at reducing this time span and, what is more important, at making one aware of the presence of those objects whose image is projected on the retina, towards the blind margins of the field of vision.
