Where does blue light come from?
Blue light is emitted from TVs, computers, laptops, tablets, smartphones, fluorescent and LED lighting. LEDs emit very strong blue light waves. Blue light is also radiated by the sun. The effects of blue light over time have a negative effect on our eyes, skin and sleep patterns.
Blue light can contribute to macular degeneration and can harm our eyes by damaging the eye’s retina. If you wear glasses, there is a coating you can put on them called blue light blocker. This is one way you can protect your eyes from the effect of blue light.
Some research has found that blue light also affects the skin by causing dark spots and premature aging. If you are concerned about your skin the good news, is you can buy a moisturizer with protection against blue light.
You can also buy screen protectors for laptop and desktop computers that will block blue light as well.
Blue light and Sleep.
Blue light reduces the production of melatonin. Melatonin is a hormone produced by the pineal gland. This hormone helps to regulate your sleep.
Melatonin is also a powerful antioxidant that protects cells and may permeate any cell in any part of the body. If you are unable to avoid blue light and find your melatonin levels are low, you can take melatonin supplements to help you.
Some smartphones, tablets, and computers have a feature that turns your display screen brightness to the warmer end of the spectrum which may help you sleep better. You can try and avoid blue light and fluorescent lights after sundown. And avoid watching TV at least one hour before going to bed.
Try the above suggestions to minimize the effects of blue light in your daily life.
