Ultimately, yes, a camera's flash is very safe for our eyes. This is due to three main factors: exposure, intensity, and focus. As most camera flashes last for just 1/400th of a second (although it might feel like a lot longer!), our exposure to the flash is very small.
How can I protect my eyes from flash?
Prevention is best. Suggestions for preventing flash burn include: Protecting the cornea from UV light by wearing coated safety goggles, or wearing a welder's mask when welding. Make sure the goggles are made to Australian Standards and cover the eyes completely.
Can camera flash give you a headache?
Light and other visual stimuli also can trigger migraine attacks: for example, flickering or pulsing lights, repetitive patterns, glare, bright lights, computer screens, TV, and movies. Fluorescent light contains invisible pulsing, which is likely why so many report it as a migraine trigger.
