The claim that "there is no scientific evidence that blue light from digital devices causes damage to your eye" I have discovered to be true, but this statement is exaggerated. After reading an article from AAO.org, it clarifies that rather than blue light causing damage to our eyes, it is simply screens in general that cause eye strain. Affects more significant to causing eye strain is lack of blinking while looking at screens and how often someone spends on electronic devices per day. A linked source from the AAO.org article, ajo.com (American Journal of Ophthalmology), backs up the argument that blue light from digital devices does not alter the symptoms of eye strains. The article mentions that the common use of blue light glasses have no different than a pair of clear lenses would. However, according to the article from AAO.org and one from Pubmed.gov, they state that blue light does have degrade sleep quality.
