Know the 20-20-20 rule to take care of your eye health

One of the most widely used techniques to treat computer vision syndrome is the 20-20-20 rule.

During this period of confinement due to the COVID-19 crisis, we spend many hours in front of the computer screen. Teleworking, video calls or pure entertainment make us neglect our eye health and give priority to other issues.

One of the measures that Óptica Fernández Baca recommends is to apply the 20-20-20 rule . What does it consist of? Every 20 minutes you must look away from the screen for 20 seconds and focus on something that is about 6 meters away.

With this technique, the appearance of Computer Visual Syndrome is prevented, a disorder caused by the effort of the eyes as a consequence of a prolonged period in front of a screen. You'll recognize this syndrome by symptoms such as eye strain, headache, redness, blurred vision, and dry eyes.

Other recommendations to prevent it consist of blinking more frequently, resting 5 minutes every hour or keeping the computer monitor about 60 centimeters away and slightly below eye level.
