    They’d get really sunburnt and maybe end up with visual damage from accidentally glancing at something brighter than they evolved with. Ditto for how you or I would do under Sirius or Vega (“blue” stars).

    The short answer: it depends.

    Humans are a product of evolution and natural selection. We evolved skin as a protection against UV radiation, but we also need some of the Sun’s radiation to support some metabolic processes. Also, our eyes work well with the light produced by our sun.

    And in an indirect way, we evolved to eat certain plants that thrive on our Sun’s light. Animals that we eat also eat some of those same plants.

    So what would happen to a person that evolved on a planet with a red sun? Maybe nothing. Maybe they’d be blind. Maybe they’d starve. Who can say for sure?

      Sunburn, maybe? I’d look up the different wavelengths emitted. I don’t think there would be anything like plants becoming inedible.
