Computers and smartphones are now one of the indispensable items in our lives. However, the blue light emitted by these electronic devices is believed to be harmful to the skin. You can learn more about how blue light affects your skin .
In this article, we will explain the measures to take when using computers, tablets and smartphones for long periods of time for work or study.
8 ways to protect your skin
1. Reduce screen brightness
The brighter the LCD screen, the easier it is to see, but this increases the effect of blue light.
When using the monitor for a long time, it is recommended to reduce the screen brightness to a level where text is not difficult to read.
2. Change the blue light level setting
Many smartphones and PCs are equipped with a blue light reduction function. There are also apps that can automatically adjust the amount of blue light, so you should make good use of these.
3. Avoid using electronic devices for a long time
Prolonged exposure to blue light leads to the accumulation of skin lesions so it is recommended that you take a 15-minute break after using electronic devices for an hour.
4. Paste the blue light barrier
If you want to protect your entire face from blue light, we recommend using blue light blocking panels that can be attached to smartphone and computer screens.
5. Use anti-blue light glasses
Wearing blue light blocking glasses can reduce eye strain, in addition to preventing hyperpigmentation around the eye area.
6. Don't touch your smartphone before going to bed
When you play with your smartphone in bed before going to bed, the distance between the screen and your eyes tends to become closer.
The amount of blue light is inversely proportional to the square of the distance, so if you use your smartphone at half the usual distance, you will be exposed to four times as much blue light.
If you use your phone 30 minutes to an hour before bedtime, light can disrupt the body's internal clock.
7. Actively Absorb Lutein
Lutein is a nutrient that helps protect the retina from blue light and is also known as "natural sunglasses".
It's found in green and yellow vegetables like spinach, carrots, pumpkin and broccoli, as well as in egg yolks, so it's important to eat foods that contain lutein.
8. Consume foods rich in antioxidants
Blue light creates peroxide in the skin, which attacks cells. Therefore, it is recommended to supplement foods with strong antioxidant properties.
・Foods rich in vitamin A:
Green or yellow vegetables like squash, tomatoes, and carrots.
・Foods rich in vitamin C:
Citrus fruits, green or yellow vegetables like bell peppers, broccoli, cauliflower, potatoes, etc.
・Foods rich in vitamin E:
Nuts, vegetable oils and seafood.
You may have heard that you should use sunscreen to protect your skin from blue light, but it's not really necessary.
This is because blue light does not cause sunburn. Most of the blue light we are exposed to during the day is likely to come from sunlight, not from smartphone or computer screens.
Therefore, indoors, we do not need to bother applying sunscreen as long as we follow the above measures correctly.
However, when going out, you should wear sunscreen with SPF50+ and PA++++. In addition to sunscreen, you should also wear a hat, sunglasses, and UV-blocking clothing to optimally protect your skin from the sun.
