"This got me thinking: why is there nothing out there for people who don't wear glasses?" Patel researched the effects of blue light and found that exposure to it can stop you sleeping.
But a new study of the specific effects of blue and green light suggests that the real story is more complicated.
The study is "the most extensive assessment of the effects of blue and green light on human circadian physiology to date," says Derk-Jan Dijk, a sleep physiologist at the Surrey Sleep Research Centre in the United Kingdom.
Jennings Bryant conducted a two-year longitudinal study of the effects of Blue's Clues at the University of Alabama in 2001, to ascertain whether or not the show's curriculum goals were achieved.
In 2002, Crawley, Anderson, and their colleagues conducted another study on the effects of Blue's Clues, this time researching whether more experienced viewers mastered the content and cognitive challenges faster and easier than first-time viewers.
However, our preliminary experiments concerning effects of blue light on L. monocytogenes yielded highly variable and sometimes conflicting results when we used a red-light dark chamber lamp for the handling of dark controls (not shown).
