Whether you are studying for a test, or pulling a long day to get an assignment completed, how can you maintain top performance when your eyes are sore and tired, and you are starting to get a monster headache?
Good posture: Make sure you are maintaining good posture and working distance from your book (14 – 16 inches) and computer screen (finger tip distance)
Good lighting: Do you have enough light? Watch from glare from secondary light sources. A window should be at your side, not in front or behind you.
Visual rest breaks: Follow the 20/20/20 rule. Take a visual rest break every 20 minutes of close work, looking greater than 20 feet away for at least 20-30 seconds. Look out the window at something in the distance to relax your focusing system. Every second break (40 minutes), get up and stretch. It is important every 2 hours to take a proper 15-minute break. Incorporate movement into your break; it helps your focusing system relax 3-4 times faster than if you just sit there.
Take a breather: After a long day of reading or computer use, go for a walk or spend some time at the gym. It will keep you physically fit and functioning at peak performance for both your body and your visual system.
