Blue-light blocking, fashion-limited orange tinted glasses were recently touted as sleep solutions in the New York Times. I was impressed with how the author framed the "blue-blockers."
The article gave a simple and responsible message: there is solid evidence suggesting that tools such as the orange tinted glasses are capable of blocking blue-light from devices or other sources and can help the body better prepare for sleep while enhancing sleep quality.
I absolutely agree with this message. I was thrilled that the author dodged the obvious temptation to suggest that wearing these glasses before bedtime will magically help you slip into a more restful slumber.
Evidence does indicate that blue-blocker glasses benefit sleep preparation and quality by blocking blue-light pollution. When artificial blue light is successfully defended before bedtime, melatonin levels are allowed to rise as they should and your body is better prepared for a more powerful sleep.
AT THE END OF THE DAY
Here's the thing - slapping these novel spectacles on before bed without addressing other aspects of your sleep environment or changing lifestyle habits that fracture sleep will likely take a bite out of their effectiveness. These orange glasses can be a great tool in your sleep enhancing quest but by themselves they will not act as a VIP credential for easy access to dreamland.
