Spy Optic McCoy Sunglasses feature Happy Lens technology that blocks harmful rays and glare while harnessing the feel-good benefits of light and providing enhanced color and contrast. In this process, long-wave blue light stimulates the brain's production of serotonin, responsible for keeping your internal clock on schedule. And that can help you feel more alert and, well, happy. And this sleek design will have you ready to race, highlighted with Dale Jr.'s signature print inside.
