In fact, the organization cites a recent study that suggests there is no reduction in eye strain with blue light-filtering lenses versus completely clear ones. One common claim is that they reduce eye strain while looking at screens on devices such as smartphones, tablets, and computers.Īccording to the American Academy of Ophthalmology (AAO), there is currently no scientific evidence that light from digital screens damages eyes or causes strain. To determine the effectiveness of blue light filtering lenses, you have to separate various claims about them.
