Health / Lenses / vision

 Technological advancement has given us new and incredible opportunities, but it also brings certain headaches, like visual fatigue.

In this generation, hearing about people being affected by Computer Vision Syndrome, caused by prolonged, restless hours on a computer, has become common. The main symptoms are red, dry or tearful eyes, headaches, somnolence, itchiness, and double or blurry vision.

 Our eyes are naturally adapted for long distance vision, so by using a tablet or smartphone, your eyes need to adapt to unnatural visual demands, causing them to work harder. However, despite all the problems they cause on our eyes, it is impossible not to use technology. More than ever, businesses are incorporating computers of touch screens for working hours, and that is something we must get used to.

In order to counteract the CVS, it is possible to use certain types of rest, and also the 20-20-20 rule, created by the ophthalmologist Jeffrey Anshel. This rule is based on that “every 20 minutes, a person must look away from their desk for 20 seconds and focus on something 20 feet away (6.09 meters).

This simple exercise allows the eyes to blink normally and for them to relax, preventing CVS. Also, a moderate distance must be kept from the monitor, between 50 cm and 1 m. By following these tips, you’ll increase your productivity, and avoid any sort of grief.
