I am sorry if I offended you. I have worked with kids since 1976 and thought I could share some of my experiences with you. Now, I am a grandfather and need to be just as careful around my grandkids. I am sorry you do not have an opportunity to reduce your risk level at work.

I have had the flashing lights symptoms for so long that I stop paying attention to them long ago. Sneezes can make the flashes very bright. I don't notice them much during the daylight but once the lights get low, the flashes are much more evident. I have been told it likely has something to do with pressure around the optic nerve.
