If your eyeglasses are tinted the blue-color coating, then they are able to block blue light. With blue light blocking coating, it is just the color that does it. There are no special filters, it’s just that amber color that does the job. Look up at the sky, you don’t see blue, all you see is a grayish/white sky but all other colors are vivid.
How can I verify that my eyeglasses are blue light blocking glasses?
