Blue-light filtering lenses reduce the amount of short-wavelength blue-violet light that passes through them. Many people choose them for screen-heavy days because they prefer the slightly warmer view.

An honest note on benefits

Research has not established that blue-light filtering lenses prevent eye disease or eye strain. Digital eye strain is commonly linked to focusing for long periods and blinking less. Habits such as regular breaks often matter more — read avoiding eye strain.
