Blue light filter lenses reduce part of the blue-violet light from screens and LED lighting. Many people find them more comfortable for long computer sessions, but research on digital eye strain is mixed, and regular breaks and the right prescription matter just as much. Think of them as a comfort upgrade rather than a medical treatment.
