How doesn’t the sun damage our eyes when it is in our peripheral vision, but it does when we directly look into it?
In: Biology
Basically it comes down to the amount of light that can hit your receptors in the back of your eye.
Draw a circle to represent the hole where light enters your eye and hold it up in from of you. Now rotate it in any direction while still being able to see it.
It should look like it goes from something like this O to something like this 0.
Any way you turn it there is less light able to go through because you’ve decreased the surface area.
Because it is not focused when it is in your peripheral vision. Your peripheral vision is actually more out of focus than you think, your brain compensates for it. It is like when you use a magnifying glass to burn something with sunlight. The lenses in your eye is the magnifying glass. As long as it is not focused, it won’t burn, the more it is focused, the more the energy (heat) is focused on a small point.
Because only a fraction of the light is getting to your eyes at that point. Sure it’s bright af but your eyes evolved under the sun and if they couldn’t take an indirect hit once and a while they wouldn’t be of much use. Think of it like the Death Star. You got shoot into a tiny little hole to blow it up. That being said, don’t play games with the sun. It will mess you up
