Our SpectraShield FL-41 lenses are not made for the same purpose as blue-blocking lenses, which block a small amount of the blue light spectrum to protect your eyes from blue light damage from electronic screens. Our lenses block a far greater percentage of the blue-green light spectrum as a portion of the light they block, which is the specific part that is shown to bother people with light sensitivity and its associated conditions. Other knockoff companies offer a generic version or other tinting that attempts to imitate, but fails to replicate, our product.
