If you experience blurry or double vision, eye discomfort, or daily headaches with vision at work, you could be dealing with eye fatigue related to extensive eye use in a challenging visual environment. Contributing factors can include eye muscle or eye focussing inadequacies, dry eyes, improper computer ergonomics, eye refractive changes, over exposure to low wavelength light, and underlying health conditions. A complete eye exam that includes a good case history, testing of visual functions, ocular health assessment, and an understanding of treatment options, are all important to diagnose and manage the problem.
