Setting up your workspace
Watch your eyes
Take frequent breaks to rest your eyes. To avoid eye strain, it can help to look away from the
monitor and focus on a distant point. Make sure your room is well-lit, and wear glasses or contact
lenses if necessary.
Adjust the position of Spectrum to eliminate screen glare from windows or light sources.
Adjust the brightness and contrast settings on your monitor to enhance text and image clarity. You
can learn more about adjusting the image on page 44.
Keep your Spectrum clean from dust and stains to maintain its readability and clarity. You can
learn more about cleaning the screen on page 59.
Blue light
Visible light contains a range of wavelengths and energy. Blue light, which has the highest energy in
the visible light spectrum, can potentially harm the eyes more than other visible light.
Sunlight is the main source of blue light, but excessive exposure to artificial blue light from
computer screens can cause eye strain and discomfort, especially in dark environments.
To reduce the amount of blue light emitted from Spectrum One, you can adjust the color
temperature to warm colors or manually adjust the color balance. You can learn more about
adjusting the color temperature on page 44.
Screen flicker
The constant on-off cycling of some monitors (also called ‘flicker’) may force your eyes to work
harder to adjust to the changes in brightness.
Prolonged exposure to flickering screens may lead to loss of focus, fatigue, headaches, and blurred
vision, especially in individuals who are sensitive to such visual stimuli.
The LED backlight unit used in Spectrum One is based on technologies that do not produce flicker
during normal use, and does not rely on pulse-width modulation (PWM).
