Do Blue Light Glasses Work?
Do Blue Light
Blue light can strain your eyes, make it harder for you to sleep, and even cause permanent damage with long-term exposure. Brush up on your blue light knowledge below to learn why using blue light glasses could be one of the smartest things you’ve ever done for your eyes!
What is Blue Light, and Where Does it Come From?
In the last few decades, though, another major source of blue light infiltrated our lives: LED-backlit screens. Television, computers, and smartphones put out high levels of blue light, and most people don’t protect their eyes from this excess blue light in any way — which has vision-threatening consequences.
The Dangers of Excessive Blue Light Exposure
Studies have indicated that exposure to blue light is related to alertness and brain functioning, so it’s not inherently harmful to you. But excess blue light, especially at certain times of day, can be damaging to your body and eyes.
Research has shown that blue light suppresses the production of melatonin (a hormone which regulates sleep) and messes with your circadian rhythm (your natural sleep cycle). Using screens at night without blue light protection can make it harder for you to fall asleep and make your sleep more irregular when you do doze off.
