Blue Light Protection

Our society has seen a dramatic increase in digital devices, fluorescent and LED lights, as well as LED and OLED televisions over the last decade.  With these advancements, the amount of high energy blue light we are exposed to has increased dramatically over.  These advancements have been revolutionary in how we communicate and learn, not to mention the decreased electricity consumption saving carbon dioxide emissions, but are they having negative effects on people? 

The Vision Council's 2015 Digital Eye Strain Report suggests that 30% of adults spend more than half their waking hours using a digital device.  As the baby boomer generation continues to age, we are seeing an increase in both cataracts and macular degeneration.  Studies are beginning to show high energy blue light is harmful to the retina possibly contributing to macular degeneration, causes eye fatigue and strain, and disrupts melatonin secretion, which regulates our circadian rhythm and sleep patterns.

The Harvard Health Letter has several recommendations to limit the effects of high energy blue light.

Use dim red light for night lights.  Red light has the least power to shift circadian rhythm and suppress melatonin.

Avoid looking at bright screens beginning two to three hours before bed.

If you work a night shift or use a lot of electronic devices, consider wearing glasses that block and/or absorb blue light.

Expose yourself to lots of bright light during the day, which will boost your ability to sleep at night, as well as your mood and alertness during daylight.
