IRIS TECHNOLOGIES



Improving the lives of people who suffer from computer intolerance


David Goldband is an accountant with Grant Thornton LLP who suffered a concussion playing hockey in January 2017. In this video he shares his story.




When it comes to recovering from a concussion, one of the persisting symptoms is the inability to look at a computer screen – a symptom that is often referred to as “computer intolerance”. With most monitors having a refresh rate of 60 Hz, the constant flickering can be a painful, if not impossible, experience. This widespread symptom can prevent concussion sufferers from returning to work and/or school. At Iris technologies, we are committed to using assistive technology to help individuals suffering from a concussion or computer intolerance reclaim their lives in our digital world.
