Harvard researchers and their colleagues conducted an experiment comparing the effects of 6 5 hours of exposure to blue light to exposure to green light of comparable brightness.
Note however that the majority of studies covered in this section deal with associations only which means that a cause and effect relationship hasn t been.
The fact that blue light penetrates all the way to the retina the inner lining of the back of the eye is important because laboratory studies have shown that too much exposure to blue light can damage light sensitive cells in the retina.
