Eye strain is a common complaint among many people today. This is in large part because we spend so much time looking at computer screens, tablets, and phones. Long periods of gazing at the same spot strains the ciliary muscle of your eye, which can tire your eyes, causing temporary blurriness. It’s possible that this strain in children can lead to near-sightedness. This occurs because of a breakdown of the eye muscles' ability to accommodate, producing a flattening the lens. Eye strain can also cause headaches, dry eyes and even blurred vision. The good news is, there are many ways to avoid this condition,and almost are inexpensive or even free. 1. use the 20-20-20 rule; When you are working at the computer, rest your eyes for at least 20 seconds by looking at something 20 feet (6.1 m) away after using the computer for 20 minutes. If you have a window nearby, looking at something outdoors is a great option.alternatively, you can move your eyes from something close to something far away, switching between the two every 10 seconds at least 10 times for a little workout. 2. Blink more. Some eye strain occurs because you tend to blink less when focusing on something, like your computer screen. Try to be conscious of your blinking while you work, and do it more often. 3. Roll your eyes; Closing and then rolling your eyes can help lubricate them. It also helps to relax straining muscles. close your eyes and roll them around in a circular motion. Roll them clockwise, then counter- clockwise. This not only helps relax your eyes, but also feels good. 4. scan the room. After a long period focusing on the screen, take a break to slowly look around the room, keeping your eyes constantly in motion and looking at things that are varying distances from you. 5. Adjust the brightness and contrast. Turn down the brightness, turn up the contrast. This will make your screen easier on the eyes. screens that are too bright are hard on the eyes. When there's not enough contrast between blacks and whites on your computer screen this is also hard on your eyes. This is because they have a harder time distinguishing between different items. This can add to eye strain.
