What the science says?

Artificial light from energy efficient computers and overhead fluorescent lighting consists of narrow bands of high energy light instead of equally balanced, full spectrum the human eye prefers. Changing the color of your screen or brightness does not affect the quality of the digital light. CE lens tints filter and balance the transmitted spectrum, reducing high energy visible [HEV] light and warming the overall view. With harsh blue light reduced, sensitive parts of the eye are engaged, increasing perceived contrast. Filtering blue light from a backlit screen reduces visual recovery time and protects the eyes. “after image” effects.
