Blue Light is the cause of many issues; some are not directly related to our vision.
This Review of Optometry article details the linkage between Blue Light, Cataracts, and AMD.
Blue Light affects our ability to sleep. One of the consequences of poor sleep is the impact on the body’s endocrine system, which regulates metabolism. This can result in over-eating and even how food is stored in the body. This article by the National Sleep Foundation reviews the relationship between sleep and obesity.
This article by the American Macular Degeneration Foundation provides a worthwhile review of Blue Light and it's linkage to cataracts and Age-related Macular Degeneration.
Many people do not understand the importance of getting at least 7 hours of uninterrupted sleep. Even fewer realize the link between poor sleep and cancer. This article by Dr. Brian Lawenda is a very important read.
This article talks about the impact of light from computer monitors on Melatonin levels in college students.
The importance of the hormone Melatonin cannot be overstated. Blue Light suppresses the production of Melatonin which is not only involved in the sleep/wake cycle, but also the Circadian Rhythm of all cells in the body. This article by the Florida Atlantic University Physics Department provides incredible insight about Melatonin.
The Environmental Health Perspectives article by David C. Holzman explores the relationship between light spectrum color, melanopsin, and even memory, along with other brain functions.
Continued exposure to dim light levels can result in depression in as little as a few weeks. As explained in this article by Dr. Mercola, the increase of Light at Night may be resulting in an increasing rate of depression. Effective filtration of Blue Light at night may help to prevent it.
This important article from the Harvard Health Authority discusses the effect of night time light which may influence shortened sleep, with serious health consequences, including Diabetes.
Digital Eye Strain
Blue Light Exposed: Digital Eyestrain Related to Long Term Consequences
Approximately 65% of Americans have reported symptoms related to Digital Eye Strain from exposure to electronic devices. This Digital Eye Strain is defined in this informative article published by The Vision Council.
Computer Vision Syndrome
Similar to Repetitive Stress Injury , the Computer Vision Syndrome occurs from looking at a computer monitor for prolonged periods of time. Between 50-90% of people are affected by it, as explained in this WebMD article.
The Retina is critical to our vision. There is no redeeming value to Blue Light’s effect on the Retina. The stress on the eye from this form of light ranges from fatigue, to oxidation, to damage of Retinal Pigment Epithelial cells. This paper by Sunnex Biotechnology is an informative perspective on Blue Light's impact.
Blue Light Reflected (glare) off of moving objects can affect how we see the objects. Reducing reflected Blue Light lessens the phenomenon of “Motion Blur”. In this fascinating technical paper on Neuroscience by the Max Planck Institute for Intelligent Systems, how the brain interprets moving objects is explored.
Sara Wylie’s article about The Hidden Danger of Nighttime Smartphone Use details the impact of artificial Blue Light from digital devices on our ability to sleep. Lack of sleep affects your memory, learning ability, retina, neurotoxin buildup, depression, obesity, and could affect your risk of cancer.
