The harm of flash lamp

Flash may cause permanent damage to your baby's eyes and retina, so don't use flash.

The retina reflects red light.

The light emitted by the flash will be reflected by the retina (just like a mirror) after entering the eyes, and then reflected by the pupil (the red area in the middle of the eyes). Because there is a layer of blood vessels around the retina, it reflects red light. Adults will also have this phenomenon.
