Why indeed ask? Most people who suffer seizures or who at risk of them, have adapted screens for themselves which are widely available through their healthcare provider, andf if they are concerned for themselves, then they will avoid reading or get their needs met.
As someone who holds a degree in psychiatry / /psychology and NHS 'train the trainer' workplace screen assessments DipEd, I do know exactly why I do it. If others choose not to read then that's their simple choice.
