Researchers from the University of Melbourne summarised data from 17 different studies from six countries on glasses with a blue light blocking function. They concluded that this is a hoax – a factor unproven by science that serves only advertising purposes.
As the researchers point out, none of their colleagues’ work directly indicates that people’s performance, vision, or other factors improve when blue light blockers are used. Some positive conclusions are untenable and can easily be criticised. On the other hand, the opposite conclusion about the uselessness of such glasses also can not be made – studies do not give such data.
