Another disadvantage the Arnam have is that they do not see as well as we do in surface daylight. Their eyes are optimized towards seeing in pitch dark, and while their multiple eyelids keep bright lights from blinding them, they lose numerous finer details in the bargain. They see the world through a haze of filters that shift the natural light spectrum, and of course they can see infrared light. They have natural heat vision, which doesn’t work so well on a hot, bright day, in the middle of a desert. But is of much more use on a cool, rainy day, in…oh…Northern Minnesota. Many Arnam happen to live there due to the pleasant, wet, and cool climate. Washington State, Maine, the British Isles, and Scandinavia house other major Arnam populations for similar reasons.
