This Position Paper summarizes a round table discussion held in London in January 2016 – chaired by Professor John Marshall with a panel of experts representing research, ophthalmology, academia and retail optometry – set out to determine the extent to which blue light is a hazard to the human eye and to establish whether it is implicated in disease such as age-related macular degeneration (AMD). Discussions included the availability of existing research and the likelihood of future studies being conducted, which will help support the increasing body of evidence that blue light is a concern for eye health. They concluded by suggesting how this potential risk should be discussed in the practice environment.
