What makes SPARKLES unique are tiny stimuli embedded in the lenses, in the peripheral vision area. The stimuli in the lenses are personally tailored based on a series of facial measurements and cognitive tests.
Their presence in the peripheral field of vision raises the low arousal level associated with ADHD. The rise in arousal leads to improved attention and better task performance.
The arousal level of people with ADHD is relatively low which leads both to weaker attention and to more hyperactive symptoms.
Research on attention also points to a close link between the disorder and the abilityto regulate arousal which is why learning, focusing (thinking about one thing at a time) and sustaining attention are harder.
