What lighting consideration helps prevent visual glare on tasks?

• A. High-intensity lighting with random placement.
• B. Proper glare control through luminaire shielding, placement, and appropriate color temperature.
• C. Using only daylight without shading.
• D. Dark finishes to hide glare.

Answer: (B)

Preventing visual glare during tasks comes from controlling the light with shielding, thoughtful placement, and selecting a color temperature that supports comfort. Shielding blocks the bright source from the eyes, so you don’t see direct glare, while placement keeps light where it’s needed for the task without shining into the line of sight or reflecting off shiny surfaces. Choosing an appropriate color temperature helps maintain good contrast and reduces eye strain, making the lighting feel comfortable rather than harsh. Other approaches fail to address glare comprehensively: lighting that’s too intense or placed randomly can create bright hotspots and glare; relying on daylight alone without shading or appropriate fixtures can still produce glare or harsh contrasts; dark finishes don’t prevent glare from the light source itself and won’t control reflections from tasks.
