Do Computer Screens Cause Eye Strain?

Modern LED flatscreen TVs and computer screens and the new LED lighting that is now widely used all cause a particular type of strain in the eyes. Bright screens and lighting cause some strain, but LED lighting can actually be harmful to the eyes. Harmful radiation comes from the blue LEDs found in all computer screens and LED-light bulbs. Unlike older incandescent bulbs and mini fluorescent bulbs and older cathode ray tube computer monitors, the blue LEDs emit high frequency and high-energy blue spectrum light has been shown to damage the chemical 11-cis-retinal in the eye and the enzymes that manufacture 11-cis-retinal. 11-cis-retinal is the chemical that allows us to see. The solution is to wear orange or nicotine colored tinted glasses that block the blue rays, or adjust the output of the computer monitor to decrease the blue radiation.
