We have chemical receptors on our tongue and in our nose for poisons. We have neurons that detect pain. Just because we can sense it doesn't mean it's not harmful.

- xvector 8y agoI don't think your argument holds. Case in point: it is possible to make poison tasty.
- dqpb 8y agoOn the contrary in fact, I find gazing at the blue sky to be calming and enjoyable, and find it promotes diffuse thinking, which can greatly speed up problem solving.
- coldtea 8y agoIt's not about merely seeing something blue, like the sky, in a generally warm temperature ambient light. It's about blue color from screens.
- astrodust 8y agoSome people like the smell of ozone. Ozone doesn't have a smell. What you actually smell is your nose burning. Ozone is a very aggressive oxidizer. Looking directly at the sun is also a super bad idea.

- foo101 8y ago> Ozone doesn't have a smell. This does not sound right. This is what I see on Wikipedia which is also exactly what I was taught in high school: > It is a pale blue gas with a distinctively pungent smell. Source: https://en.wikipedia.org/wiki/Ozone https://en.wikipedia.org/wiki/Ozone
- jcl 8y agoI'd guess that the negative effects of blue light over a lifetime might only have become noticeable in modern times, with better vision correction and treatment for conditions like glaucoma and cataracts. If so, there probably hasn't been significant evolutionary pressure to dislike viewing blue light. Also, half of outdoors is blue half the time, so instinctual blue-avoidance would probably hurt survival. But it is perhaps misleading to concentrate on things that are exclusively blue... The real problem is light containing the relevant range of frequencies, which includes many non-blue colors, due to the relative presence of other frequencies. For example, your eyes would probably absorb much fewer relevant photons when staring at an empty patch of sky than when staring at the sun, even though the sun is not considered blue. And looking at the sun does cause unpleasantness.
