These are blue light blocking glasses. The lenses are visibly coated with a blue film that blocks blue light. The goggles come with a soft faux leather case, cleaning cloth, nylon drawstring case and a "blue light test kit". The product was made in China. I love the ability of these glasses to block blue light. As a photographer, I am very sensitive to color variations and light temperatures. With these glasses I can see a subtle but noticeable color change on my computer screen and desk screen. I also see this shift when I look outside. The shift isn't as severe as some other blue light glasses I've tried, but it's still noticeable. The glasses come with a blue light test kit (torch and card) which unfortunately doesn't work as my regular reading glasses without special treatment also block the light of the test kit. However, the lenses of these blue light glasses block blue light. The cover and serviette are also useful accessories. All in all, this is a powerful pair of blue patch blockers in a stable frame.
