Hello, hello!!!!
Today I want to talk to you about an issue that concerns us all in the digital age: the
blue light emitted by the screens of our electronic devices.
While technology has made our lives easier in many ways, it has also brought with it
new risks to our health. One of them is prolonged exposure to blue light, which can
have negative effects on our vision, sleep and general well-being.
What is blue light?
Blue light is part of the visible light spectrum, and is found in shorter wavelengths than
red or green light. It is present in sunlight, but also on the screens of our smartphones,
tablets, computers and televisions.
How does blue light affect our health?
- Eyestrain: Prolonged exposure to blue light can cause eyestrain, dry eyes, blurred
vision and difficulty focusing.
- Sleep disorders: Blue light suppresses the production of melatonin, a hormone that
regulates the sleep cycle. This can lead to insomnia, nighttime awakenings and daytime
sleepiness.
- Other risks: Some studies suggest that blue light may also be associated with an
increased risk of macular degeneration, an eye disease that can cause vision loss, and
with the development of certain types of cancer.
How can we protect ourselves from blue light?
- Limit screen time: It is important to be aware of the time we spend in front of screens
and try to reduce it as much as possible.
- Use the 20-20-20 rule: Every 20 minutes, look at an object that is 20 feet away for 20
seconds. This will help relax your eye muscles and prevent eyestrain.
- Adjust your device's settings: Most electronic devices have options to reduce blue
light emission. Look for the "night mode" or "blue light filter" setting and turn it on.
- Use blue light blocking glasses: These glasses can block a significant portion of the
blue light emitted by screens.
- Sleep in a dark room: Avoid using electronic devices in bed or at least one hour
before bedtime. Blue light can interfere with melatonin production and make it difficult to
fall asleep.
Remember: Taking care of your eye health is essential to enjoying a good quality of life.
Follow these tips to protect your eyes from blue light and prevent future health
problems.
Always decide for your health.
Bye, Bye.
