Are children getting nearsighted because of technology?

Took my kid to the eye doctor today.  She said something that had me scratching my head.  She said that they (the eye doctors) are seeing more children come in needing a prescription for near sightedness because of the handheld game consoles, sitting in front of a computer, etc.
It seems anecdotal to me, at best.  Is there any truth behind what she told us?

It's not closeup work per se.  But an indoors lifestyle does promote nearsightedness.

-- light at night (electric lighting) promotes eyeball growth which promotes nearsightedness

-- closer horizons (never focusing to infinity, as you would outside) promote nearsightedness

Both of those are proven in rats.

So yes, our lifestyle promotes nearsightedness, but it's not computers specifically.  Rather it's just being indoors and an artificially lengthened day.
