Behavioral changes in autistic individuals as a result of wearing ambient transitional prism lenses . A double-blind crossover design was used to assess the efficacy of wearing ambient lenses to reduce the behavioral symptoms of autism . Eighteen autistic individuals , ranging in age from 7 to 18 years , participated in the study . Behavior , attention , and orientation were evaluated at 1 1/2 months , 2 months , 3 months , and 4 months . Compared to the placebo condition , the results showed a decrease in behavior problems at the 1 1/2 and 2 month assessment periods and a slight loss of these benefits at the 3 and 4 month assessment periods . These findings support the prediction that ambient lenses , worn without engaging in visual-motor exercises , have positive effects on autistic individuals .
