Here is what I got on the explanation of Photo Eyeplay...
I got this article from the
rightbraineducationlibrary.com website (I am also subscribe to them
)
Below is their explaination...
"This training is to train your child's ability to capture and hold an image in their mind.
For example, you can take an orange coloured card with a blue circle and get your child to stare at the cards for 30 seconds. The get your child to look at a white blank page. Your child will see an afterimage in reverse. Repeat once daily until the child get the correct after image"
From what I understand, it is suppose to train the child to see an object and then capture the image visually and mentally "seeing the image".
Photo Eyeplay is part of a right brain photographic memory exercise. This methods are widely used in Shichida Method and Heguru.
