Methods, apparatus, and articles to enhance brain function via presentation of visual effects in far and/or ultra-far peripheral field

A method for operating a device for use with a user having a pair of eyes, the device including:

• at least one visual effects generator operable to successively generate a plurality of visual effects that are non-contextual with respect to content appearing in a central field of vision of at least one of the eyes;
• and at least one optic optically coupled to the at least one visual effects generator and positioned rearward of the pair of eyes and oriented to present the generated visual effects at least in a respective ultra-far peripheral horizontal static field of at least one of each of pair of eyes, the ultra-far peripheral horizontal static field of each eye which extends rearwardly from a fovea centralis that extends forwardly of a pupil of the respective eye in a straight ahead static gaze direction to at least 100 degrees or more rearwardly from the fovea centralis of the respective eye thereby to cause display of generated visual effects to the user having the pair of eyes from behind the pair of eyes of the user, the method comprising:
• successively generating, by at least one visual effects generator, a plurality of visual effects that are non-contextual with respect to content appearing in a central field of vision of at least one of the eyes and wherein the visual effects do not constitute a cursor, a user input field or other user input or control user interface element;
• and
• presenting, via at least one optic, the generated visual effects at least in a respective ultra-far peripheral horizontal static field of at least one of each of two eyes of a user, the ultra-far peripheral horizontal static field of each eye which extends rearwardly from a fovea centralis that extends forwardly of a pupil of the respective eye in a straight ahead static gaze direction to at least 100 degrees or more rearwardly from the fovea centralis of the respective eye.
