have you been watching your computer screen since last couple of hours ?

Dear friends, don't watch your computer screen continuously  for a long time. Have a break after every 30 minutes.
The hazards of watching the computer screen for a long time are;

• Headache (Migraine)
• Dimness of vision
• Blurring of vision
• Fatigue
• Lethargic feeling
• Blackouts
• Eye pain
• Watering of eyes.
• Even decrease in cognitive ability

To avoid it after every 30 minutes  choose a distant point and focus on it for some time then close your eyes and put your palm on your eyelids in  such a way that no light crosses from your finger spaces. wait for 15 to 30 seconds and then continue your work. Repeat this procedure after every 30 minutes
