Our eyes have a protective layer of tears which cover the surface of the eye. This layer of tears serves several purposes, including maintaining proper nutrition to the eye tissue and clear vision. If this layer of tears becomes defective, it will likely lead to a burning sensation. In order to compensate for this burning, the eyes can become red very easily when the body requires more blood into the area.

Studies have shown that people tend to stare more (blink less often) when looking at computer screens. This occurs for a few different reasons, but it always leads to tear problems. Our blinking is important in maintaining our tear layer. Without it, the tears evaporate too quickly and lead to dry eye and burning conditions. I won’t be foolish enough to say, "Remember to blink", because it’s impossible to do work and think about blinking at the same time. However, you should know that blinking is important to reduce burning of the eyes. It will be easier for you to blink if your computer monitor is in a lower position on your desk (not sitting on your CPU). This allows your eyelids to be closer together, making it easier to blink.

Likewise, redness can be caused by a number of reasons. If the eyes dry or begin to burn, the body senses the need to nourish the area, and increases the call for blood to the area. However, an infection or any number of eye diseases can also cause redness of the eyes. If the redness persists for more than a few days, you should have it professionally evaluated to assure it is not a serious eye disease.
