Binary lenses to the rescue!
Vinnie at 5 ½ was doing well in kindergarten. He was cooperative, pleasant, and successful, that was until her broke his binary lenses. Binary lenses have a special slight tint and prism to facilitate various behaviors. He had a slight yellow tint to facilitate attention and focus. His replacement lenses were standard clear lenses. Suddenly he was a monster. He could not sit still; he was mean and unproductive. Interestingly, he had trouble sleeping and was generally cranky. Once he had his binary lenses with a mild yellow tint, he settled down.
Color is therapeutic when appropriately applied.
