How Does Blue Light Affect Our Health?
We’ve heard before that blue light can disrupt our natural sleep rhythms. This is because our eyes have blue light photoreceptors. This means that having a blue light in your room while you sleep can suppress the hormone melatonin, which is needed for healthy sleep.
Now, ANSES, the French agency for Food, Environmental and Occupational Health & Safety, found evidence to confirm the ‘phototoxic effects’ of short-term exposure to high-intensity blue light. Someone suffering from phototoxicity is overly sensitive to light on their skin and eyes.
They also found that the retina in our eyes can become damaged due to chronic exposure to low-intensity sources of blue light. This is a problem because it can increase your risk of age-related macular degeneration, which is the leading cause of vision loss in America, especially for those over 50.
What is Age-Related Macular Degeneration?
Age-related macular degeneration is an aging-related change of the cells that make up the infield of the retina. The area responsible for sharp vision becomes damaged over time, thus leading to vision loss. And, unfortunately, there is no known cure.
