I get these every couple of months! Sometimes with accompanying headache, sometimes without. That picture is a great representation of what I see. Although I would say its usually more silvery and shiny. Dunno what triggers it, I've had it sitting watching TV, tryjng to work on computer (which becomes impossible) and just sitting in a restaurant eating lunch. Normally lasts half an hour or so. Also sometimes I can be left feeling fuzzy and foggy for a day or so after. Like you say reading just becomes impossible! Have you found any good medication that helps when they trigger?
