Nowadays, usage of computers and screen-based electronic devices such as mobile phones and tablets are inevitable. Prolonged usage of digital devices often strains the eyes, and increases risk of CVS disease, which is very common. Dr. Pichit Naripthaphan, ophthalmologist at TRSC International LASIK Center, will give you more information.
Computer Vision Syndrome (CVS) are symptoms caused by staring at digital devices for a prolonged period of time (more than 2 hours), especially in poor lighting conditions and with improper screen brightness. Blurred vision, eye fatigue, dry eyes, eye irritation, and pain around the eyes are common symptoms of CVS. Headaches and neck, shoulder and back pain due to bad posture are also common. Those with uncorrected visual problems such as farsightedness and astigmatism are at higher risk of CVS.
Best solutions to prevent Computer Vision Syndrome
1. The 20-20-20 rule. Every 20 minutes, look away from your digital screen and stare at an object 20 feet away for 20 seconds. When you use computers for more than 2 hours, take a 15-minute break.
2. Try to blink frequently (20-22 times per minute). Blinking also helps to keep your eyes moist.
3. Rest with your eyes closed for 2-3 minutes for every half an hour.
4. Adjust the font size on the screen to see clearly and comfortably and consider using a screen glare filter.
5. Avoid areas with bright external lighting.
6. Adjust the screen lighting.
7. The computer screen should be 15-20 degrees below eye level as measured from the center of the screen and 50-70 cm from the eyes.
Eye health is of the upmost importance to maintain a healthy lifestyle. Computer Vision Syndrome (CVS), although common, can be avoidable. Take good care of your eyes and have regular eye examinations to detect diseases at the earliest stage when they are most treatable.
