This is a nice example of Chinese whispers at work. No proof was presented that blue light speeds up blindness, and besides that the amount of blue light in normal sunlight pales in comparison with the output of your average monitor. Sunlight is about 1 KW/sq meter, an LCD display is a very small fraction of that (which is why most displays except for e-ink are impossible to read in full sunlight).
