I swear, they like to live in a news studio-level brightness. Its all overhead lighting and bright, cool light at night

Absolute sensory hell for me.

Straw poll: which looks better?

Theyre both too brightly lit imo but the warm is definitey nicer. I want to escape any room place lit like the right

Tap for spoilerNow, imagine its like the cool white, but its even brighter and o'erhead💀

Skeleton's be cool white...

Kinda makes sense, altho I wonder if they also just dont notice or feel the impulse that they can just change whatever the default lighting situation is also

    Pupils dilate in darker lighting, the bigger the aperture, the narrower the depth of field get. if you have old eyes that aren’t as good at focusing anymore, narrowing the aperture will cheat that and allow sharper focus, but you need more light to do it.

    You can see this if you have an old SLR camera with DOF preview, and focus on a scene with object both close and far. As you close down the aperture (move it to a higher number say 2->16), you’ll see more and more of the scene simultaneously in focus, but it will also get darker and darker.

    That’s why old people make rooms brighter. It’s easier on their eyes if they wish to see things in focus.

    Edited for spelling

    Actually, my one eye nearsighted and i noticed if I physically focus it by using my fingers to create a smaller "aperture", i can actually see farther with the nearsighted one!
