Hi,
I have checked with my family eye specialist and he says it is OK to use the iPad or any computer screen. It does not spoil the eyes.
My sister got the Brillkids reading program, math program and
rightbraineducationlibrary.com (for her Shichida flashcard practice) a few years ago.
I don't see any problem with her daughter. In fact my sister's daughter is doing very well and that is the reason I am joining brillkids and also the right braineducationlibrary.
