DES: Causes/Solutions So what is Blue Light anyway?
5. Glare and Blue Light § HEV light that appears white, but has a large blue light component
Reflection off walls and screens § Exposes the eye to hidden spikes in intensity at wavelengths within
the blue portion of the spectrum. (400 to 450nm)
§ Solution § Emitted by digital devices and modern day lighting
• Front and Back surface AR
• Anti-Glare screen monitor
• Adjust Room Lighting (Lamps vs. Overhead lights)

cycles in the human body by aiding in cognitive functions
§ Night Shift Iphones
§ Alertness § SleepShield
§ Memory § Twilight
§ Emotion Regulation
§ LowBlueLights
§ Mood § BioBrite

Teenage Boy Sleep Study Blue Blocking vs. UV Blocking
§ 13 teens between 15 -17 yrs
§ Individuals with sleep difficulty were divided into two groups who
§ 1 week wearing Blue Blocking lenses between 6pm - bed
wore lenses 3 hrs prior to bed.
§ 1 week wearing Clear lenses between 6pm - bed
§ Blue-blocking – Amber tinted lenses
§ Ultraviolet blocking - Yellow-tinted lenses
Conclusion:
§ Participants who wore the blue-blocking glasses observed :
§ Felt sleepier with Blue Blockers
§ 50% increase in sleep quality
§ Higher Melatonin levels measured in saliva with Blue Blockers
§ 40% happier after they woke up

Blue Blockers and Melatonin Production Digital Devices and Dryness
§ Melatonin level production was measured after wearing § Decreased blink rate from 18X minute to 7-8 X minute
Sunglasses vs Blue Blockers:
§ Poor tear film stability
§ Regular sunglasses - 46% decrease in melatonin
§ Major cause of CL dropout (20% over past 10 years)
§ Blue-blocking glasses - 6% increase in melatonin
