These blue lights also cause digital eyestrain - also known as computer vision syndrome - that comes with symptoms which include dry, irritated eyes and blurred vision. Prolonged exposure can also cause retinal damage.
The blue light emitted from electronic devices messes with your sleep cycle. It signals your brain to wake up when it should be winding down by slowing or stopping the release of the sleep hormone - melatonin.
