Course Description

In recent years, high-energy visible (HEV) blue light has been one of the most talked-about topics in eye care. Much of this emphasis on blue light has grown from concerns about potential harmful ocular effects of extensive and sustained use of computers and other digital devices that have luminous LED displays. In this course we will address these concerns from three perspectives: What is it blue light and why are we talking about it? What science-based evidence is there to support claims? What claims are based on speculation and still under debate?
