Here is a link to video presentation which Dr. Charles Tator, a neurosurgeon at Toronto Western Hospital, gave at a 2017 “Concussion in Women and Girls Conference” in Toronto. His presentation is currently available online. In this presentation, Dr. Tator provides some information about women with Post Concussion Syndrome (PCS) who experience photosensitivity (a.k.a. photophobia). He also describes a study that he was involved with where they had 29 people with PCS use a “non LCD” device instead of a traditional computer monitor. The device had a slower refresh rate (so less flicker) than a typical computer monitor and did not have a backlit screen.
