220-1102 Practice Question: A technician is setting up a new workstation in a…
A technician is setting up a new workstation in a cubicle. The user complains of eye strain and glare from the overhead lights. Which environmental adjustment should the technician recommend first?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Rotate the monitor 90 degrees so the light hits the side of the screen.
Glare from overhead lighting is a common cause of eye strain. The simplest and most effective fix is to reposition the monitor so that the light source is perpendicular to the screen, reducing direct glare.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace the overhead fluorescent tubes with LED bulbs.
Why it's wrong here
Replacing overhead fluorescent tubes with LED bulbs is a costly and indirect solution that primarily addresses flicker, not glare. While modern LEDs produce less flicker than older fluorescent ballasts, glare is fundamentally caused by the angle and intensity of light reflecting off the screen surface into the user's eyes. This action does not directly alter the problematic reflection angle, making it an inefficient first step for glare reduction.
- ✗
Apply a matte screen filter to the monitor.
Why it's wrong here
A matte screen filter reduces glare from the monitor’s own surface reflections, but the user’s complaint specifically identifies overhead lights as the source of eye strain. The correct first adjustment is to reposition the monitor or adjust the lighting angle to eliminate direct overhead glare, which the filter does not address. This option is tempting because matte filters effectively diffuse ambient light on the screen, making them the correct choice when the glare originates from windows or desk lamps rather than ceiling fixtures.
- ✓
Rotate the monitor 90 degrees so the light hits the side of the screen.
Why this is correct
Rotating the monitor 90 degrees effectively changes the angle at which the overhead light strikes the screen, directing the reflected glare away from the user's line of sight. Glare occurs when a light source's reflection is directly visible, so repositioning the display perpendicular to the light source minimizes this direct reflection. This is a fundamental, zero-cost ergonomic adjustment that directly addresses the root cause of reflective glare.
- ✗
Increase the monitor's brightness to overpower the glare.
Why it's wrong here
Increasing the monitor's brightness attempts to make the screen content more visible by overpowering the glare, but it does not eliminate the glare itself. This approach can significantly worsen eye strain and discomfort by creating a higher contrast ratio between the bright screen and the surrounding environment. Furthermore, it can exacerbate the fatigue caused by the reflective light source, rather than resolving the underlying issue.
