Found
here:
"Asthenopia (eye strain) – a sense of fatigue brought on by use of the eyes for prolonged close work or in persons who have uncorrected error of refraction. Symptoms are usually aching or burning of the eyes, accompanied by headache. "
Also I found something interesting
here, and the point that is relevant for the discussion would be "(c) The reading conditions":
"The brightness ratio between a book and the surrounding table surface should be 1:1 ideally, but a value of 3:1 is acceptable. Beyond 5:1 there is some impairment."
