Do Blue Light Glasses Work?

Answer:

Multiple studies (such as a 2017 University of Houston study) suggest that blue light glasses, such as those with zFORT® blue light protection, can take an active role in protecting your eyes from harmful types of light. This is done by filtering out ‘blue’ light with a wavelength between 415nm and 455nm.

 

The light that reaches your eyes is altered which, against glaring screens, protects your eyes from digitally-emitted blue light which, according to a 2012 Harvard study, may cause numerous eye health-related problems such as eye strain and headaches.
