What are the real effects of blue light on eye health and sleep?

In the digital age, children and adults spend an average of more than 6 hours a day in front of screens. This can cause both eye strain and disrupted sleep patterns.

Myth: Blue light from screens causes permanent damage to the eyes. Truth: There is no scientific evidence to prove permanent damage, but long-term use can lead to dry eyes and headaches.

Myth: All types of blue light are harmful. Truth: Natural blue light from sunlight is beneficial for improving mood and brain function.

Exposure to artificial blue light in the evening reduces the hormone melatonin and makes it harder to fall asleep. It is recommended to stop screen use 1-2 hours before bedtime.

To protect your eyes, follow the "20-20-20" rule: every 20 minutes, look 20 feet (about 6 meters) away for 20 seconds.

Enable "night mode" on your devices and adjust the screen brightness according to the environment. Remember to blink frequently to reduce eye fatigue.

Even if your vision is perfect, it is important to have regular eye exams if you spend a lot of time in front of a screen. Healthy eyes mean a healthy future!
