Many cheap blue light reducing computer glasses claim to block more blue light than they actually do.
Many brands now include a blue laser pen with their glasses to "prove" clear lenses block blue light.
This is nothing more than a scam and they actually dont block any blue light that is found in LED back lot devices such as laptops, Mac books and smart phones.
We use our spectrometer to test the laser pen and expose the scam that many of us have fallen prey too.
Make sure you stick to a brand you can trust
