as someone that sits at a PC for 12 hr shifts for work, they work wonders.... I ordered a pair as a deal of the day, and never looked back, got a second pair for at home use. I don't use them as much at home but i'm not reading as much text at home either vs work. I can vouch for them making a difference though. (also if you don't need a prescription the cost is reasonable)
That said it is a odd move, musta been a big pay increase or something behind the scenes.
