I found the below passage on Page 3 of the Ipad Manual regarding eye strain, headaches, blackouts, etc. From the below passage, Apple notes that this phenomena can occur from playing games or watching movies on the Ipad. However, I also experience dizziness and eye strain from watching the movement of words/photos/ pictures move across the Ipad screen. I hope that Apple would, in the future, place the below "Warning" on Page 1 of the Manual instead of burying it within Page 3. I question how young children are responding to this new Ipad technology, specifically those with special needs.
Page 3 Ipad Manual:
Seizures, Blackouts, and Eyestrain A small
percentage of people may be susceptible to
blackouts or seizures (even if they have never had
one before) when exposed to flashing lights or light
patterns such as when playing games or watching
video. If you have experienced seizures or blackouts
or have a family history of such occurrences, you
should consult a physician before playing games
or watching videos on your iPad. Discontinue use
of iPad and consult a physician if you experience
headaches, blackouts, seizures, convulsion, eye or
muscle twitching, loss of awareness, involuntary
movement, or disorientation. To reduce risk of
headaches, blackouts, seizures, and eyestrain,
avoid prolonged use, hold iPad some distance
from your eyes, use iPad in a well-lit room,
and take frequent breaks.
