Pc and Laptop, and blue light
Very interesting information about the research on night vision using white and red lights
at night. Most informative I think.
But, most of you seemed to have missed the point of the information. The purpose of the posting was to make you all aware of the health danger from exposure to the blue wavelength light emitted from monitors. By reducing the light output from monitors of PC and unfiltered Laptops helps minimizing the circadian-disrupting blue light that is harmful to our health.
