A four-step eye exercise can relieve tired eyes after long hours of working in front of the computer screen. Do it daily, particularly in between breaks from the computer. Step 1: Close your eyes tightly for 3- 5 seconds and open them for 3-5 seconds. Repeat 7-8 times. Step 2: Close your eyes again and massage in circular movements for 1-2 minutes. Step 3: Press three fingers against upper eyelids, hold for 1-2 seconds then release. Repeat 5 times. Step 4: Roll your eyes clockwise, then counter-clockwise, and then blink once. Repeat 5 times.
