What is dry eye syndrome?
People these days who are accustomed to digital devices do not blink well. Those who look at computers and smartphones may develop dry eye syndrome due to prolonged exposure to the air. Dry eye syndrome is a common disease affecting approximately 330 million people worldwide.
It is common to experience discomfort in the eyes or a feeling of a foreign body while staring at a computer screen for a long time. Normally, tears act as a lubricant for the eyes, so they are always kept moist. However, when the eyes are exposed to digital devices, wind, air conditioners, or heaters for a long time, tears are not enough and the eyes become dry easily.
Dry eye syndrome is characterized by extreme fatigue in the eyes, inability to focus, or a feeling of foreign body even when there is nothing in the eye. The eyes may also be red or swollen. Occasionally, the eyes become itchy and sensitive to bright light. If these symptoms are left unattended for a long time, it will naturally affect the eyesight.
How to prevent dry eye syndrome
Prevention of dry eye syndrome before it occurs is very important. First, exercise to help prevent dry eye syndrome is as follows.
- Close your eyes and suddenly open your eyes.
- Then look at least 10 meters (about 30 feet) away.
- Repeat this 5 times for about 1 minute a day.
If you do this exercise after staring at a computer or smartphone for a long time, you may feel your vision spinning, or your vision may become slightly blurred due to a sudden distance in focus. Doing this on a daily basis will help prevent dry eye syndrome.
Blinking frequently is another way to prevent dry eye syndrome. It is effective if you close your eyes slightly and then close them tightly again. If you repeat this exercise 20 times a day, the number of blinks increases and the amount of tears produced automatically increases. Many people forget to even blink, so it is necessary to intentionally increase the number of blinks.
If you need to use the computer frequently, wearing computer glasses or special lenses can also help prevent dry eye syndrome. In addition, if you adjust the angle of the computer monitor to go down slightly, the moisture in the eyes is less exposed to the air, which is effective in preventing dry eye syndrome.
