Vision has evolved numerous times, with estimates suggesting eyes or light-sensitive spots have appeared independently at least 40 to 65 times, possibly even 100 times, across different animal lineages.

Hearing has evolved numerous times independently, at least six times in major vertebrate groups (mammals, lizards, frogs, birds, crocodiles, turtles) for airborne sound and at least 19-20 times in insects

Vision and hearing have evolved so many times because they give an absolutely huge survival advantage.

Do you have sources for these claims?

To my knowledge, photosensitivity has arisen a few times independently and eyes again a few times from shared photosensitive receptors in animalia but I'm fairly sure hearing in the groups you mention is a tetrapod synapomorphy.
