Our blue light filtering lenses are clear—they do not have any noticeable yellow tint. Because the lenses are clear, some customers worry that the lenses may be the wrong type and are therefore not filtering blue light.
We've put together a video below to demonstrate how these clear blue light filtering lenses work. In the video, pay attention to the light and shadows behind the lenses. You will see that when the blue light is shined through the right lens, there is a shadow, meaning the blue light is not passing through the lens.
