Why is good lighting important in ergonomics?

Answer and explanation

Correct answer: To reduce eye strain

The direct answer is A, reducing eye strain. Ergonomics aims to fit the workplace to human needs so that work is safer, more comfortable, and more efficient. Good lighting lets the eyes see text, tools, and surfaces clearly without excessive squinting or effort. The reasoning is: adequate, suitably directed light improves visibility; better visibility reduces unnecessary eye effort; reduced effort can lessen discomfort, headaches, and errors. Option A is correct. Option B is wrong because the purpose of workplace lighting is not to hide work. Option C is wrong because making a room appear small has nothing to do with visual comfort or safe design. Option D is wrong because lighting does not increase noise; noise is a separate environmental factor. Lighting should also avoid strong glare, deep shadows, and reflections, and should suit the task. Memory cue: clear light, comfortable sight, safer work.
