Here's a conclusion on fatigue in reading from visual display units (VDUs),
from Dillon (1994) - _Designing Usable Electronic Text_:

"It would seem safe to conclude that users do not find reading from VDUs
intrinsically fatiguing but that performance levels may be more difficult
to sustain over time when reading from average quality screens. As screen
standards increase over time this problem should be minimized."
