ELI5; Why/ how do our eyes interpret bright light as painful?

925 views

For example being used to a dark room, and then walking into another that’s much brighter and having a pain response while adjusting to the new lighting.

I dunno if i would call it exactly as pain..it’s feels more of like a natural response of our body to close our eyes when bright light is concentrated at it.. just like gaging is a natural response.

I have a fascination with the sun and I certainly did not have any pain when i used to look directly at it for 5 to 10 seconds when i was a kid.. you do start seeing with weird colors and it’s like a whole different world though.

I’m not encouraging anyone to do it unless you want permanent eye damage but that’s one of my experiences of bright light.
