One of the things you can do is get a pair of yellow tinted glasses. Gundar makes a specific one for gamers but I prefer the ones from Oakley. They make staring at computer screens for long periods of time easier.
Another thing to be aware of is symptoms of diabetes. Are you are sitting in a chair in front of a computer for hours a day, years on end? Do you eat sugary or stachy foods, coke or energy drinks for instance? Do you not get exercise? Have you gained a lot of weight? Do you have a lot stress in your life (startups)? Depending on your body type this type of environment can lead to diabetes. One of the symptoms of that is blurred vision.
