Research into light sensitivity shows how the human eye responds to “invisible light,” impacting several important biological functions

Melanopsin in the human eye signals the circadian rhythm cycle and is most activated by blue light in the visible spectrum. Disruptions to melanopsin via blue lit electronics can effect sleep cycles and even migraines and light sensitivity. The effect is cumulative and damage can produce early macular degeneration among other sight disorders. It’s best to limit blue lighting from artificial sources, particularly at night before bed and buy computer and phone screen filters to reduce emissions.

Key Takeaways:

  • Excessive use of mobile devices are to be avoided if you wish to get a proper night’s rest. This is because the melanopsin protein is sensitive to blue light and establishes our circadian rhythms (day-night cycle). Mobile device use should be done in short periods and avoided prior to sleep.
  • Some individuals even have physical reactions to bright lights, resulting in severe migraine headaches and in others, epilepsy.
  • Blue light, from electronic devices, can cause cataracts and other forms of retinal damage. Aside from loss of vision, it can accelerate age-related macular degeneration. Long-term exposure to these artificial rays can cause abnormal hormone secretion, poor heart rates, lack of alertness, and sleep disorders.

“Recent studies on the mammalian eye shed light on why some people have excessive light sensitivity. These new discoveries may contribute to developing effective therapies for individuals who experience migraine headaches and concussions with light sensitivity.”
