Wikipedia is in fact, an unreliable source. Do you know what would happen to my english grade if i used wikipedia as a source on a paper? "thermal" damage even from the sun.... isn't it also caused by the IR heat from the sun? I think that why they say to never look into the sun just like we say to be careful with IR lasers.. But perhaps I am wrong. We haven't covered the whole chapter on light in physics yet..
