You spend too much time on the computer
Yet another reason not to stay glued to the computer (or video game or Smartphone) for too long: It can cause your eyes to dry out. Why?
“Using the computer significantly decreases the blink rate and that’s how you lubricate your eyes,” says Cushing.
Blinking, which happens an average of 10 to 15 times a minute (roughly every four seconds), keeps the eyes moist with the proper balance of tears, oil, and mucus.
Blinking less often means tears evaporate more quickly. This can also occur with other activities involving intense concentration and focus such as reading, driving, or even sewing.
