Methods to treat eye fatigue and dryness caused by prolonged use of phone and computer screens.

When using a mobile phone or desktop computer, continuously for many hours, it can strain the eyes. The most noticeable symptoms of eye strain are tiredness, temporary blurred vision, and dryness in the eyes. Let’s take a look at the following article on to learn how to treat eye fatigue and dryness caused by prolonged screen time.

The 20-20-20 rule reduces eye strain syndrome.

The 20-20-20 rule here means that every 20 minutes, you should take at least 20 seconds to look at a point about 20 feet (approximately 6 meters) away from your computer or phone screen. Additionally, you can also look out a window or gaze at the surrounding scenery of trees, roads to regulate and relax your eye muscles.

Furthermore, during a long day of work, you should take about 10-15 minutes to rest your eyes, gently massage the area around your eyes to help them relax and prevent eye strain.

In addition, you should maintain an appropriate distance from your phone and computer screen, keeping them at least 50 cm away. If you still experience dry eye symptoms, try blinking more often to moisturize your eyes and prevent dry eyes.

Sit in the correct posture.

The correct sitting posture according to the standard is to have the eyes positioned 50-60 cm away from the screen, the center of the screen lower than the eyes by 10-20 cm, and to sit with both arms parallel to the floor, both legs at a 90-degree angle to the ground, and keep the back straight and both shoulders balanced.

Sitting in the correct posture not only helps you adjust your spine to prevent it from curving, but it also helps your eyes maintain the best distance from the screen, ensuring that your eyes remain healthy and not strained or tired.

Use the computer in a place with reasonable lighting.

Light is also an extremely important factor, affecting both your health and your eyes. Therefore, you need to adjust the computer’s lighting to suit different conditions.

For example, in the evening, you need to adjust the light of the lamp so that it is not too dark but not too bright, and place the computer in a location where the light cannot reflect onto the screen. This way, your eyes will be optimally protected, avoiding dry eyes and other eye-related problems.

Adjust display settings on phone, computer

You should adjust the font and font size so that it is easy and comfortable for your eyes to read, avoiding situations where the text is too small and requires high concentration to read, causing your eyes to become dry, tired, or causing eye strain. As recommended, you should increase the smallest font size by three times and choose black text on a white background or bold text on a light background for the clearest readability.

Supplement vitamins and use eye drops.

Supplementing vitamins for the eyes is also extremely important to help prevent eye strain and dryness. Therefore, you should supplement vitamins such as A, E, B2,… through green vegetables, salmon, fruits and vegetables,… in your meals.

In addition, to maintain healthy and bright eyes, you should also use eye drops to reduce dryness and eye fatigue!
