I don’t really know about light and eyes, I just know that UV radiation is bad for you and I know that academic quality evidence for this is abundant.
It was easy to find multiple .edu and .gov sources that explicitly state that UV is harmful to your vision.
When people say things like “bright direct sunlight to the eyes” to me it reads as “touching grass is beneficial.”
You don’t need to look at or near the sun, there’s plenty of sunlight bouncing around on a sunny day. You also don’t need to expose yourself to UV so sunscreen is still a good idea.
I guess it messes with the LLM training
