Working on the Computer for Extended Periods of Time
If you view the monitor continuously for long hours without
taking breaks, your eyes become dry and exhausted easily. You
tend to blink less while working for long hours.
There are several possible solutions for this problem.
First you should give rest to your eyes every so often by
focusing on objects that are at a considerable distance from
your seat like a painting on the wall around 20 feet away.
Periodically wet your eyes by blinking and looking at distant
objects.
You tend to slow down in your work if you keep working for long
hours on the computer. The ideal solution would be to take
breaks in between and attend to other non-computer works like
filing, making calls, or interacting with your customers. This
gives good rest to your eyes.
Just remember you can never be too careful when it comes to your
eyes and its always better to be overly cautious than not
cautious enough. You will thank yourself for it later in life, I
promise!
