Nowadays, using mobile phones is considered a normal part of our daily lives. But playing with your smartphones in the dark can cause serious damage to your eyes. This is because in a dark environment, our pupils dilate to accept more light, allowing more blue light from the phone screen to enter your eyes than usual. This can cause eye irritation, eye pain, and disrupt sleep.

Blue light is light that everyone can see in the white light range. White light is divided into 7 colors: purple, indigo, blue, green, yellow, orange and red. Blue light is a mixture of blue and indigo. Blue light is a high-energy light similar to ultraviolet (UV) radiation คาสิโนออนไลน์ UFABET ฝากถอนรวดเร็ว เริ่มต้นเล่นง่าย. Playing with your phone in the dark for a long time causes the following symptoms:

• Eye irritation or stinging
• Dry eyes, sensitivity to bright light
• Eye strain and discomfort
• Unable to adjust focus from one distance to another as well as possible
• Blurred vision while reading text and when looking into the distance

How to avoid the dangers of using your smartphone in the dark

• Drink plenty of water to keep your eyes moist. If you have very dry eyes or wear contact lenses, use artificial tears when your eyes are dry.
• Adjust screen brightness appropriately. Install a blue light filter app and adjust the screen brightness to suit the environment. Do not use the highest brightness when using the phone in the dark. The room should have sufficient light to reduce the difference between the light from the phone screen and the environment. If possible, choose to use Night mode, which will help soften the color tone of the screen, reduce interference with the melatonin hormone that helps with sleep, and set the automatic light adjustment according to the time.
• You should not lie on your back to play with your smartphone because the screen will not receive light from the ceiling lamp. Even lying on your side can cause your eyes to stare at the screen more than usual.
• Rest your eyes regularly. You should use the 20-20-20 rule: every 20 minutes of using your phone, look at an object 20 feet away for 20 seconds to relax your eye muscles. You should also avoid using your phone in the dark as much as possible for your own eye safety.

Finally, if playing with your phone when the lights are off is your constant behavior, by now you should be able to see the dangers, which are more serious than you thought. Stop hurting yourself and switch to using your phone in a room with enough light.
