Why is keeping a computer screen too close to the eyes wrong?

Answer and explanation

Correct answer: It can strain the eyes

Direct answer: Option D is correct. Keeping a computer screen too close can strain the eyes. Ergonomics means arranging tools and the workplace so that the body can work safely, comfortably, and efficiently. When the screen is very near, the eyes must keep focusing at a short distance. This may produce tired eyes, dryness, difficulty focusing, headache, or temporary discomfort, especially during long work. The correct practical response is to place the screen at a comfortable distance, keep it near eye level, reduce glare, and take regular short breaks. Option D works because it identifies the real health effect: eye strain. Option A is wrong because screen distance does not increase the computer’s sound. Option B is wrong because sitting close does not break the chair. Option C is wrong because the physical distance of the screen cannot make the table smaller. These options do not describe an ergonomic effect on the worker. The exact comfortable distance can vary with screen size and person, so one rigid number should not be assumed here. Memory cue: screen too close means eyes work too hard; think eye comfort, not sound or furniture.
