One of the purposes of our skin is to produce pigments that absorb the UV before it gets to the delicate livings cells underneath. If the glass dome permits UV transmission, you need to wave a few more wands to explain why their brains are somehow immune to what should otherwise be very dangerous radiation exposure. | |

Specifically high purity silica glass (fused silica SiO2) and sapphire (Al2O3). materion.com/resource-center/newsletters/…. The bigger problem is that 99% of UV-C light is absorbed by the atmosphere. The lack of natural UV-C light on Earth is why bacteria never evolved to resist it; so, it is unlikely any bacteria on a planet could not resist it's own sun's UV rays. | |
