Features
Blue light ranges from about 400nm to 500nm which is high energy and casts a glares. A blue light filter is an optical filter design that reflects or a blue light (440~500nm) and allows the rest visible light through.
Via vacuum-coating, a blue light filter can block harmful blue light at 415~455nm and let the visible light at 400~680nm transmit at the same time to reduce digital eye strains and improve the quality of reading.
