computer sore eyes

Hey... anyone heard of this "Computer sore eyes"
Do you know what is the cause and how to prevent this from happening?

Computer users experience eyestrain, blurred vision and other visual symptoms related to sustained use of the computer.
This is caused by poor lighting conditions, glare and distracting reflections, increased hours on the computer.
To prevent, always remember to blink with your eyes. Studies have shown those that work and read much at computer screens blink less, which in return dries the eyes.
