The ER on the 14mm Meade doesn't concern me at all - I don't need glasses and my eyesight (so far) is still pretty good, even though I stare at computer screens for 12+ hours a day.
Iceman. I read a book the other day about eyestrain while reading computer screens. You need to set an alarm that goes off about every 7 minutes. When it goes off simply look up to the ceiling or out the window and allow your eyes to focus. Otherwise you could be doing damage.
