What harm does camera flash do to children's eyes?

Can't use, the flash will make the pupil contract quickly, and the iris of the fundus will be congested, so it is harmful to the eyes. In particular, the high-power flash in the studio cannot be used, which is very harmful to invisibility. You can ask them to use a fixed-focus lens with large aperture, such as 1.4 or 1.2. If it really doesn't work, they can use reflectors outdoors. If it doesn't work, they can use soft boxes. I hope I can help you.
