Haylen, flashing AND flourscent lights are triggers for me. They give me those aura headaches and I cannot concentrate with either or both of those. I will probably have seizures sometime during the day or that evening if I have to be around them very much. Thankfully, mine are only partial complex seizures, not the grand mals that some have to deal with.
I am glad I quit FB back in 2010 for many reasons...
