Interestingly, I read a while back about polarized light being visible to a portion of the naked eye. http://rspb.royalsocietypublishing.org/content/282/1811/2

Interestingly, I read a while back about polarized light being visible to a portion of the naked eye. http://rspb.royalsocietypublishing.org/content/282/1811/20150338 http://rspb.royalsocietypublishing.org/content/282/1811/2015... I found that I was able to see Haidinger's brush infrequently. One experiment (which I sadly cannot remember a citation for) suggested that lines in the sky would point north/south.

Interesting... Also, I forgot to mention that the lines would curve around the light of large stars. It was almost like the oval notches/holes in wood grain. Only the large/visible stars did this.
