In my story, a character is temporarily blinded with a harsh flash of light. Would her eyes show any sign of it, e.g., would her pupils be extremely constricted?
Your pupils automatically contract in bright light to prevent too much from entering your eye. Therefore, in a bright flash, your pupils would immediately contract a lot.
And on the pedestal these words appear:/'My name is Ozymandias, king of kings;/Look on my works, ye Mighty, and despair!'/Nothing beside remains. — Percy Bysshe Shelley
