LCD and LED computer and television screens, smart phones  tablets and GPS all emit blue light. Although blue light in itself is a natural phenomenon -it is present in daylight and helps us stay awake-  over-exposure can cause eye strain, eye fatigue and even sleeplessness.

Hoya BlueControl is a coating that neutralises the blue light emitted by digital devices, keeping the eyes in better condition. It offers more comfortable and relaxed vision and better contrast perception, preventing eye strain and fatigue.
