I can’t give you an ELI5 answer, however it’s called [Photic sneeze reflex](https://en.wikipedia.org/wiki/Photic_sneeze_reflex).

Personally I think that – to make it ELI5 – the “wires” from the eyes to the brain run next to the “wires” from the nose, and that they have bad shielding, so that when a very strong signal runs through one set of wires, it can leak into the other set of wires.
