During a recent visit to an optician, one of my friend was told of an exercise for the eyes by a specialist doctor that he termed as "20-20-20". I thought I should share this will all of you. It is applicable to all of us who spend most of the time sitting in front of computer.
20-20-20:
Step 1:
After every 20 minutes of looking into the computer screen, turn your head and try to look at any object placed at least 20 feet away.
Why? This changes the focal length of your eyes, a must-do for the tired eyes.

Step 2:
Try and blink your eyes for 20 times in succession
Why? To moisten your eyes

Step 3:
Time permitting of course, one should walk 20 paces after every 20 minutes of sitting in one particular posture.
Why? Helps blood circulation for the entire body.

Eyes are mirror of the soul, so do take care of them, they are priceless...



I have written a small batch file for windows which locks my screen every 20 minutes. I will share the procedure to do the same :
Step 1:
Copy the following contents into a file, say "lock.bat" (Dont miss .bat extension)
Step 1:
Copy the following contents into a file, say "lock.bat" (Dont miss .bat extension)
@echo off
rundll32.exe user32.dll, LockWorkStation
cls
Step 2:
Goto Scheduled Tasks
(Start --> All Programs --> Accessories --> System Tools --> Scheduled Tasks)
Step 3:
- Create a new scheduled task (File --> New --> Scheduled Task)
- Double click on that and a dialog box opens.
- In the Run option, Browse the .bat file saved.
- Check the box "Run only if loggod on".
- Goto schedule Tab. Make the necessary changes and then click on Advanced settings.
- Check the box "Repeat Task" and fill the values that suits you. (I scheduled for 20 min and duration as 24 hours).
Now your screen locks for every 20 minutes. If you dont want to lock your screen but you need to get an alert after 20 minutes the change the batch file to the following code:
@echo off
echo.
echo Turn your head and try to look at any object placed at least 20 feet away.
echo.
pause
