• numbness, or a burning or tingling sensation
• aching, soreness or tenderness
• pain, swelling or throbbing

- Adjust the display brightness and/or contrast to a comfortable level for enhanced text readability and graphics clarity.
• Eliminate glare and reflections by:
- placing your display in such a way that the side faces the window or any light source
• minimizing room light by using drapes, shades or blinds
• using a task light
• changing the display's viewing angle
• using a glare-reduction filter
• using a display visor, such as a piece of cardboard extended from the display's top front edge
- Avoid adjusting your display to an awkward viewing angle.
- Avoid looking at bright light sources, such as open windows, for extended periods of time.
Developing good work habits
