I thought you could go blind looking at the sun.

Edit: My title was worded badly. I meant how people don’t go blind. I understand why people look at sunsets, just not how they do blind. That’s my fault.

Edit: Thanks for all the replies and clarification!

Here’s what I learned incase anyone else has had the same question as me, the reason we don’t go blind is that we’re usually looking at the colours of the sky during a sunset and only some few second glances at the sun.

Looking at the sun also doesn’t make us go blind during sunrise and sunset because the light rays have to go through more atmosphere, so by the time they reach your eyes, the rays are weaker. It’s fine to look at the sun for a few seconds when it’s more red than white or yellow.

Again, thanks for all the clarification.

  • You don’t usually look directly at the sun, just the sky itself as it changes colors. At just the right time of twilight (dawn or dusk), the sun isn’t even visible, but it’s light can still be seen turning the sky a pretty gradient of blues and purples or reds and yellows.

    Tell me you live in a city without telling me you live in a city.

    But srsly it’s because it’s beautiful and unique every time. And the sun is below the horizon when we are looking

    When the sun is very low (nearly touching or even partly below the horizon), it’s typically shining through such a large amount of atmosphere that the sunlight is significantly weakened by the time it reaches your eyes. This isn’t always true though, for ex if the air is unusually dry, clear, or thin (such as near the poles). Good rule of thumb is that if it looks red rather than yellow or white, it’s likely safe to look at for at least a few seconds.

    You don’t look AT the sunset. You look at what the sunset does to the scene in front of you.

    The sun high up in the sky produces light that has to go through a thin layer of air to reach you, and is really powerful. It’s so much light that it can burn your retinas. The sun near the horizon produces light that goes through hundreds of miles of atmosphere, scattering a lot of the light, and the remaining light is safe to view.

    Because it might be their last. *The one gloomy commenter. We are looking at the sky change colors and not directly at the sun. As everyone else said on this thread.

    Patterns of vivid color might be stimulating to us because in the ancestral environment, they meant survival-critical things like “this is a tasty fruit” or “here’s the water in the desert”.

      They did also mean “this is highly poisonous”, so some wires might have been crossed along the way.

    Because it is beautiful and interesting to look at, especially if your in the right place. The same rule applies to sunrises as well, a d a good place for that is pretty place, sc
