Narbis’ neurofeedback glasses use NASA-derived technology to help you practice attention so you can perform at your best. The glasses’ sensors measure the wearer’s brain patterns and deliver instant feedback on attention by tinting when distracted and clearing again when concentrating. Practice attention to stay on task, regardless of the activity: reading a book, studying, working at the computer, or doing a craft. Find out more at http://bit.ly/getnarbis
