I have a question about photo eye play and stimulation cards.
What ages are they good for? (I have a 14 month old. Is he old for this? Is it helpful for my 6 year old, too?)
How often and for how long does one use them?
If they come in a set of two (one a negative of the other), do I stay with one set? Or do I move on to a different pattern?
I’m rather new with this concept. Any other related info would also be great. :yes:
Thank y’all for always being so helpful! 
Good question! I would really like to read a response to this question as well.

With PhotoEyePlay video you can accelerate and open the centers used in after-imaging games simply by watching the videos. The rich colors on the screen activate optic centers used for seeing and holding an after-image – vital for improving your photographic memory. Basic colors and shapes make the after-images POP! Visual perception is heightened, and you may feel a “tingling” sensation within the brain by viewing this short, yet effective video.

From what I gather it’s even for adults. :yes:
