TEMPO.CO, Jakarta - A research from the University of Toledo reveals that blue light from smartphone screen can cause blindness.
The study found that blue light causes toxic reactions in retinal molecules in the eye that sense light and signals the brain. As a result, the poisonous chemical reactions kill the photoreceptors in the eyes and cannot be recovered once they die.
To avoid serious problems, it is best to immediately save your eyes from the blue light of the smartphone screen in the following easy ways:
1. Rest your eyes for a moment
Stop staring at the smartphone screen every 20 minutes for 20 seconds. Then look at something 20 feet away. It aims to temporarily relax the eye muscles and give your eyes a little rest.
2. Blink more often
When you concentrate on your smartphone, your blink rate also decreases. It can cause the tears on the surface to dry and leads to irritation, redness, pain and blurry vision.
Blinking more often will make the eyes moist and reduce irritation. At least blink about 10 times every 20 minutes.
3. Lower the glare
A bright or glare screen can make the eyes get tired faster. If possible, equip your smartphone with anti-glare glass or you can download a light-reduction application to reduce the blue light.
4. Give distance between eyes and smartphone
Holding your smartphone only about 8 inches from the face is very bad for the eyes. Give a distance of at least 16-18 inches from the eyes. Maybe it will feel strange for the first time, but you will get used to it.
5. Turn off smartphone before bedtime
According to the National Sleep Foundation, blue light can also affect your sleep by suppressing the production of the hormone melatonin. This hormone plays a key role in the regulation of the sleep cycle. So, turn it off at least 30 minutes before bedtime.
6. Adjust the brightness and contrast of the screen
Having screen brightness that is too high or too low can cause eyestrain. So, adjust it to your comfort.
7. Splash eyes with water
Splash your eyes with water regularly. This activity will ward off irritation and reduce dryness in the eyes. This can also reduce problems such as blurred vision and help the eyes to focus better.
From now on, keep your eyes health before it is too late, as reported by Boldsky.
