This is good advice, I just got my first pair and they make a huge difference in comfort, and being able to stare at a screen throughout the day. Particularly if you are nearsighted and already wear glasses, the need for computer glasses may sneak up on you. I found that by afternoon/evening my eyes were tired and having problems focusing on a screen with my regular glasses. The way my eye doctor explained it, there's two compounding problems - we start losing the ability to focus up close in our 40s, and distance-vision glasses push the near focus point further out. Eventually the near point is close to or further than the distance to your monitor/laptop, and your eye muscles have to strain to be able to focus.
