With longer working hours and an increase in the use of technologies such as computers, our eyes are being put under more and more strain.
To avoid eyestrain take regular breaks. Breaks will not only relax the eyes but the whole body as well. A good rule to follow is the 20-20-20 rule; every 20 minutes of looking at the computer screen, turn your head and try to look at an object placed greater than 20 feet (6 metres) away. This changes the focal length and relaxes your eyes; a must for tired eyes.
You may also try to blink for 20 times in succession, to moisten eyes and walk 20 paces every 20 minutes of sitting in front of the computer. This will not only focus the eyes at different distances as you move around but also help with blood circulation for the entire body.
If your job requires you to wear protective eyewear never go without it. Your employer should provide the protective eyewear.
