When shooting in the studio, do you consider the model's "red eye" and pupil dilation?

Red eye appears because: the sudden light shines on the eyes, and the pupils of the eyes have not had time to contract, resulting in red eye. So as long as it is a sudden light, it will form a red eye, which has nothing to do with the studio. When you use a flash or even a flash in the shed, you may form a red eye. At present, some flashlights have pre-flashing function, that is, before the shutter is officially pressed, the flashlight flashes several times to narrow people's eyes and avoid red eye. In short, no matter in the shed or not, there will be no red eye without sudden light.
